All of the techniques described in the above documents are intended to color a molded glass body or an unmolded glass plate without significantly changing its shape. It adopts a method of fusing colored materials. A method in which deformation and coloring of the glass body progresses at the same time while the glass body is in contact with a general metal body, and a colored part appears on the surface by peeling off the metal body from the glass body bonded to the metal body. It is not yet known how to do so.

Focusing on the above points, the present invention heats a glass body to a temperature at which viscous flow occurs, deforms the glass body that has become a viscous fluid, and adheres it to a metal body to cause a chemical phenomenon for coloring. An object of the present invention is to manufacture a shaped article having a unique shape and a clear colored layer by peeling off a metal body from a glass body that has cooled and joined with the metal body.

When the glass body is heated until it becomes a viscous fluid, the network structure of silicon dioxide (SiO ₂ ), which is the main component of the glass body, is loosened. Particles and ions ionized from the particles migrate to the glass body and enter a state of active movement (diffusing) in the network structure.

Therefore, when the metal body containing the transition metal element is heated together with the glass body and the glass body, which has become a viscous fluid, is brought into close contact with the surface of the metal body for a predetermined period of time, oxygen ions in the silicon dioxide on the glass side and A chemical reaction occurs with the transition metal ions on the metal body side to generate a metal oxide, and a phenomenon occurs in which the particles of the metal oxide and the transition metal ions contained in the metal oxide diffuse inside the glass body. it is conceivable that. In particular, the surface layer of the portion of the glass body that is in close contact with the metal body has a high distribution density of the above-mentioned particles and ions, and a unique color appears according to the wavelength range of light absorbed by these particles and ions.

In the present invention, based on the above considerations, a metal body containing a transition metal element and a glass body are placed in a kiln with a predetermined positional relationship, the kiln is heated, and the glass body becomes a viscous fluid by heating. and the metal body are brought into close contact in a high-temperature kiln. This close contact causes the phenomenon described above, and a colored layer derived from the metal oxide generated by the close contact with the metal body is formed on the surface layer of the portion of the glass body that is in close contact with the metal body.

Thus, in the present invention, the temperature of the glass body is raised to the extent that viscous flow occurs, and a portion of the glass body is brought into close contact with the metal body while the glass is deformed. Produces metal oxides. The conventional methods described in the above-mentioned Patent Documents 1 and 2 and Non-Patent Document 1 are all based on the premise that the colored layer is formed without significantly deforming the glass body, and the metal generated for coloring The oxide does not contain a component derived from glass either. In the method described in Patent Document 3, the glass body and the metal body are superimposed and heated. is not mentioned at all.

The heating in the kiln may be stopped at an appropriate timing after the temperature of the glass body reaches a predetermined temperature equal to or higher than the working point. Also, if the metal body and the glass body are supported in a superimposed state when put into the kiln, it becomes easy to bring the flowing glass body into close contact with the metal body. As long as the body can be in close contact with the metal body, any positional relationship between the two may be set.

In the present invention, the glass body having the colored layer formed thereon and the metal body are further cooled until they are bonded together while keeping the two bodies in close contact with each other, and then at least part of the metal body is removed from the glass body. Carry out the peeling process. By doing so, the part where the colored layer is formed appears on the surface and can be observed from the front. Further, if the glass body is transparent or translucent, the colored layer can be seen through from the surface of the glass body where the colored layer is not formed by removing the metal body that blocks the light. .

In order to peel off the metal body from the glass body that has hardened at a temperature lower than the glass transition point, it is necessary to bend the metal body relatively easily. From that point of view, it is desirable to make the metal body thin.

When the metal body and the glass body are arranged vertically and supported inside the kiln, either one may be on top. For example, when both are supported so that the metal body is at the bottom and the glass body is at the top, the glass body, which has been turned into a viscous fluid by heating, can be caused to flow and deform on the surface of the metal body.

Contrary to the above, when both are supported inside the kiln with the glass body at the bottom and the metal body at the top, the glass body, which has become a viscous fluid due to heating, is deformed by the pressing force of the metal body. be able to.

In the present invention, when a metal body provided with at least one through-hole penetrating through the thickness portion is used, the metal body is arranged such that the thickness portion of the metal body extends along the vertical direction, and the through-hole portion in the plane serving as the lower surface is formed. Support it at a position higher than the inner bottom of the kiln so that the opening is not blocked. Then, the glass body is arranged so as to face a predetermined range including the in-plane through portion that is the upper surface of the metal body, and the glass body that has flowed in the kiln in a high temperature state adheres to the upper surface of the metal body, and furthermore, After a portion enters the penetration, the glass body is allowed to flow until it moves into position below the penetration.

According to the above process, a colored layer is formed on the portion that was in close contact with the perimeter of the through portion of the metal body, and a modeled object (for example, the modeled object shown in FIG. 201) can be obtained.
The above-mentioned penetrating portion may be formed as a complete hole that penetrates the thickness of the metal body, or may be formed in the edge portion of the metal body as a form in which a part of the hole is missing or as a notch. There is (the same applies to the following embodiments).

When using a metal body having a penetrating portion, a second metal body containing a transition metal element is further supported at a position facing the penetrating portion in a lower height range than the metal body. The glass body may be made to flow so that the tip portion of the glass body that has entered is in close contact with the surface of the second metal body. In this way, the metal oxide produced by the close contact with the second metal body and the transition metal ions therein are not only present around the penetrating portion but also at the tip of the convex body. A colored layer can be formed by being diffused (for example, a modeled object 202 in FIG. 6, which will be described later).

The first and second metal bodies may be made of the same type of metal material, but if they are made of different types of metal material, the color of the portion in close contact with the metal can be made different depending on the type of metal.

A metal body having a bottomed hole with a curved inner surface is used, and the glass body is placed on the open end surface of the bottomed hole, or the glass body is placed at a position higher than the inner bottom surface inside the hole, You can also heat the kiln. In this case, the curved surface corresponding to the bottomed hole is formed by deforming the glass body so that the flowed glass body changes to a state in which the glass body is in close contact with the inner bottom surface of the bottomed hole along the inner surface of the bottomed hole, It is possible to obtain a modeled object with a glass body in which a colored layer is formed on the surface layer portion of the curved surface.

In the present invention, a metal body containing a transition metal element is formed into a form having a hole with at least one open end face (for example, a form having a bottomed hole or a cylindrical body as described above), and a plurality of glass bodies ( It is also possible to put a metal object containing a glass plate of a certain size, a spherical glass, a small piece of glass, etc. into the kiln and start heating. In this case, each glass body that has become a viscous fluid by heating is fused in a kiln in a high temperature state to change into a single glass body that adheres to the inner surface of the hole along the inner surface of the hole. The metal oxide produced by the contact between the body and the metal body and the transition metal ions in the metal oxide are diffused inside the glass body, and the metal is formed on the surface layer of the portion of the glass body that is in close contact with the metal body. A colored layer derived from the oxide can be formed.

In the present invention, when two kinds of metal bodies containing a transition metal element are used, one of them (the first metal body) is to be peeled off from the glass body, and the other (the second metal body) is subjected to one or more The following method can be implemented by having a through portion.

First, a second metal body is placed on the first metal body so that the penetration direction of the through part is along the vertical direction, and a predetermined range including the in-plane through part which is the upper surface of the second metal body is formed. Each metal body and glass body are supported inside the kiln and heated in the kiln.

After that, the glass body, which has become a viscous fluid by heating, is allowed to flow in a kiln at a high temperature while being in close contact with the upper surface of the second metal body, so that a part of the glass body passes through the through-hole and enters the first metal body. The glass body is deformed so that it also adheres to the surface of the As a result, the metal oxide generated by the contact between the glass body and each metal body and the transition metal ions in the metal oxide are diffused inside the glass body, and the portion of the glass body that is in close contact with each metal body is dissipated. A colored layer of metal oxide can be formed on the surface layer.

Furthermore, after the glass body and each metal body are kept in close contact with each other and cooled until the glass body is bonded to each metal body, the first metal body is peeled off from the glass body. The second metal body is held bonded to the glass body.

According to the above method, the colored layer derived from the metal oxide produced by the close contact between the glass body and the first metal body and the colored layer derived from the metal oxide produced by the close contact between the glass body and the second metal body It is possible to obtain a shaped article having a configuration in which the second metal body is integrally provided with the glass body including the colored layer. In this case as well, the first metal body and the second metal body may be made of the same kind of metal material. The colors of the colored layers can also be different.

Instead of the second metal bodies having the through-holes, a plurality of second metal bodies having a size that can be placed on the first metal bodies are provided above the first metal bodies with a predetermined interval therebetween. can be placed in In this case as well, the glass bodies are arranged so as to face the range in which the second metal bodies are distributed. The formed glass body is brought into close contact with the portion of the second metal body that is not in contact with the first metal body in a kiln in a high temperature state, and is caused to flow so that a portion of the glass body is placed between the second metal bodies. By deforming the glass body so that it also adheres to the surface of the first metal body through the gap, the surface layer of the part of the glass body that is in close contact with each metal body is formed by the contact. A colored layer derived from a metal oxide can be formed.

Furthermore, after the glass body and each metal body are kept in close contact with each other and cooled until the glass body is bonded to each metal body, the first metal body is peeled off from the glass body. As a result, it is possible to obtain a shaped object having a configuration in which a plurality of second metal bodies are provided integrally with a glass body including a colored layer based on the first metal body and a colored layer based on the second metal body.

According to the present invention, a glass body that has become a viscous fluid by heating and a metal body are brought into close contact with each other in a high-temperature environment, and the glass body is deformed by the viscous flow or the pressing force of the metal body, thereby obtaining a unique shape. A clear colored layer derived from transition metal ions can be formed on the surface layer of the glass body having

Furthermore, in the present invention, the colored layer can be seen through from various directions by peeling off the metal body, which is a light shielding body, from the glass body that has been cooled and bonded to the metal body.

FIG. 1 schematically shows an example of a modeling method according to the invention.
In this method, a plate member 1 (hereinafter referred to as "metal plate 1") containing a metal containing a transition metal element (for example, copper) and a plate glass 2 are used.

The metal plate 1 is a thin plate with a thickness up to about 1 mm. The plate glass 2 is a transparent glass body made of general soda glass, and has a thickness larger than that of the metal plate 1 but a main surface smaller than that of the metal plate 1 . The main surfaces of both the metal plate 1 and the sheet glass 2 can be of any shape, and there is no need to match the shapes of the respective surfaces.

In this embodiment, a plate glass 2 is placed on the metal plate 1, placed on a support table 4 having heat resistance, and placed in an electric kiln (hereinafter simply referred to as "kiln") not shown. (FIG. 1(A)), the temperature inside the kiln is maintained at about 700 to 800° C. and heated for a predetermined time. During this time, the plate glass 2 softens and becomes a viscous fluid, and is deformed by surface tension on the surface of the metal plate 1 (FIG. 1(B)). The surface of the metal plate 1 is also oxidized by heating and the color changes.
In addition, the kiln used for the above heat treatment need not be limited to an electric kiln.

Hereinafter, glass that has softened to become a viscous fluid will be referred to as "fluid glass" or simply "glass" and indicated by reference numeral 20 in the figures. Also, the fluid glass that has been deformed cools and hardens again is called "modeling glass" and is indicated by reference numeral 21 in the figure. When referring to the glass 2, 20, 21 in each state including the sheet glass 2 in the text, they will be referenced only when describing the figures in which they are represented.

In this embodiment, the heating is stopped when the fluid glass 20 changes into the shape shown in FIG. Then, when the fluid glass 20 cools down to form the shaped glass 21 and is bonded to the metal plate 1, the combined body is taken out of the kiln and further cooled at room temperature for a while. Then, when the temperature of the modeling glass 21 and the metal plate 1 reaches a temperature (40 to 50° C.) that can be touched by hand, the metal plate 1 is pulled from the modeling glass 21 as shown in FIG. 1(C). By peeling off, a final modeled object is obtained only by the shaping glass 21 .

In the above heating process, when the fluid glass 20 is largely deformed, the surface layer portion of the portion of the glass that is in close contact with the metal plate 1 is in a state in which the colored layer 3 with a predetermined color is included (see FIG. 1 ( B).). The colored layer 3 is also maintained on the modeling glass 21, and when the metal plate 1 is peeled off, the portion where the colored layer 3 is formed appears on the surface.

The above-mentioned colored layer 3 is made up of metal oxide particles and transition metal ions in the metal oxide generated at the interface between the glass 20 and the metal plate 1, which are viscous fluids in which particles and ions are actively moving. It is thought to be caused by the absorption of light in a specific wavelength range by these particles and ions (coloring with a color corresponding to the wavelength range that was not absorbed by the particles and ions).

In fact, the inventors placed a copper metal plate 1 with a thickness of 0.1 mm and a plate glass 2 with a thickness of 3 mm in the supporting state shown in FIG. When the temperature was maintained at around 750° C. for about 5 minutes, it was confirmed that a dark red colored layer 3 was formed at the portion of the fluid glass 20 in close contact with the metal plate 1 (copper plate). When the thickness of the colored layer 3 was measured when the fluid glass 20 cooled and became the shaped glass, the thickness was about 100 μm. The colored layer 3 in this case is believed to be derived from copper oxide.

When the same experiment as described above was performed by replacing the copper plate with a stainless steel plate (SUS430), a light green colored layer 3 was formed at the portion of the fluid glass 20 in close contact with the metal plate (stainless steel plate). This colored layer 3 was also maintained even after the fluid glass 20 became the shaped glass, and was confirmed to have a thickness of about 100 μm by measurement. The colored layer 3 in this case is considered to be mainly derived from chromium oxide.

All of the colored layers could be seen through the part of the shaped glass where the colored layer was not formed. Furthermore, when the temperature of the modeling glass and the metal plate reaches a temperature (40 to 50°C) where they can be touched by hand, the metal plate is peeled off from the modeling glass to remove the side on which the colored layer is formed. As the surface was exposed, the colored layer was also reflected on the convexly curved surface, and a glass modeled object that seemed to be colored almost entirely could be obtained.

In the basic method shown in FIG. 1, the plate glass 2 is placed on the flat surface of the metal plate 1 and both are heated in a kiln. A method is adopted in which the body 12 is placed on a support base 4 (only the upper surface is shown in this figure) with the open end facing downward, and the plate glass 2 is placed on the convex surface of the metal body 12 and heated. may In this case, only the central portion of the initial plate glass 2 contacts the metal body 12 (FIG. 2A), but the fluid glass 20 that has been changed by heating has almost the entire lower surface covered by the metal body due to the action of gravity. 12, and the colored layer 3 is formed on the surface layer of the adhered portion (FIG. 2(B)). The colored layer 3 in this case is also maintained even after the fluid glass 20 cools down to become the shaped glass 21, and when the metal body 12 is peeled off from the shaped glass 21, the part where the colored layer 3 is formed is exposed to the surface. appear (Fig. 2(C)).

In the examples of FIGS. 1 and 2, the sheet glass 2 is superimposed on the metal plate 1 and the metal body 12 and placed in the kiln. If so, the plate glass 2 may be supported at a height slightly away from the metal surface by a method such as suspension.

When the metal plate 1 or the metal body 12 and the plate glass 2 are supported with a space therebetween, contrary to the examples of FIGS. The metal body 12 may be supported (when the metal body 12 is arranged on the plate glass 2, the direction thereof is reversed from that shown in FIG. 2). Regardless of the vertical relationship, the metal body and the glass body, which face each other vertically at a predetermined interval, can be brought close to each other by placing a weight on the uppermost surface of the metal body and the glass body.
Alternatively, the metal plate 1 or the metal body 12 and the plate glass 2 may be arranged side by side on the support base 4 .

In the following, by applying the manufacturing method shown in Fig. 1, a shaped object having a unique shape and a colored layer derived from transition metal ions is manufactured by greatly deforming the fluid glass while adhering it to the metal body in a high-temperature environment. An example will be described. All of the examples are based on examples in which the inventors actually tried and succeeded in forming a colored layer.

FIG. 3 shows a modeling method corresponding to a first application.
The metal plate 10 used in this example has a thickness similar to that of the example shown in FIG. A portion of the metal plate 10 around the through hole h is placed on a pair of support stands 4a and 4b arranged facing each other inside the kiln so that the space between the support stands 4a and 4b is filled with the through hole. It is supported with h facing each other. The plate glass 2 has the same structure as in the example of FIG. 1, and is superimposed on the upper surface of the metal plate 10 supported as described above (FIG. 3(A)). However, in this example as well, the plate glass 2 may be supported at a position separated from the metal plate 10 by a predetermined distance.

When the kiln is heated after the setting described above, the glass 20, which has changed to a viscous fluid as the internal temperature of the kiln rises, adheres and flows to the surface of the metal plate 10, and the portion disposed above the through hole h. begins to descend due to the action of gravity (Fig. 3(B)). The portion around the through hole h also descends, thereby forming the fluid glass 20 into a shape having a portion 24 that stays on the surface of the metal plate 10 and a portion 25 that largely hangs down from the through hole h (Fig. 3 (C )).

Metal oxide particles generated by the close contact with the metal plate 10 and transition metal ions in the metal oxide are present in the surface layer portion on the bottom side of the portion 24 of the fluid glass 20 remaining on the surface of the metal plate 10 . , and a colored layer 3 is formed by absorption of light in a specific wavelength range. Metal oxide particles and transition metal ions are scarcely diffused in the portion 25 that flows into the hole and hangs down without adhering to the metal, so that the colored layer 3 is not formed either.

In the first application example, after the fluid glass 20 deformed to the state of FIG. A modeled object in the final form consisting only of the glass 21 is obtained.

FIG. 4 shows the shaped glass 21 corresponding to the final shaped shaped object 201 manufactured according to the first application example, viewed obliquely from below.
In this modeled object 201, the portion 24 that remained on the surface of the metal plate 10 when it was the fluid glass 20 becomes the collar portion 24a, and the portion 25 that hangs down from the through hole h is a transparent convex body having a hollow portion. 25a and is continuous with the central portion of the collar portion 24a. The bottom surface of the brim portion 24a is nearly flat, but the top surface and edges include curved surfaces and uneven surfaces that reflect the deformation of the fluid glass. The surface of the convex body 25a also becomes a curved surface reflecting the shape during flow.

The above-described colored layer 3 is formed over substantially the entire surface layer of the bottom surface of the collar portion 24a. The colored layer 3 can be seen through from above the shaping glass 21 or from an obliquely upward direction. In addition, depending on the direction of the line of sight, the colored layer 3 is also reflected on the transparent curved surface body 25a, and shines brightly like a pattern, enhancing decorativeness.

FIG. 5 shows a modeling method corresponding to a second application.
In this example as well, the metal plate 10 and the plate glass 2 having the same configuration as in the first application example are placed inside the kiln in the same relationship as in the example of FIG. 3(A). Further, a low support base 4c is arranged between a pair of support bases 4a and 4b for supporting the metal plate 10, and the second metal plate 11 is placed thereon (Fig. 5(A)). ).

The two metal plates 10 and 11 may be made of the same kind of metal material, but in this example, they are made of different metal materials. For example, the upper metal plate 10 is a stainless steel plate with a through hole h in the center, and the lower metal plate 11 is a copper plate without holes.

In the second application example, the glass 20, which has become a viscous fluid, is deformed so as to hang down from the through hole h by the same method as in the first application example (FIG. 5(B)). The flow of the glass 20 is controlled so as to continue until it reaches the lower metal plate 11 and the contact state is maintained for a predetermined time (FIG. 5(C)). As a result, in the deformed fluid glass 20, the first colored layer 3 derived from the metal oxide generated by the close contact with the metal plate 10 is formed on the surface layer of the bottom surface of the portion 24 remaining on the metal plate 10. At the same time, the second colored layer 30 derived from the metal oxide generated by the close contact with the metal plate 11 is also formed on the surface layer portion of the tip portion of the hanging portion 25 .

In this embodiment as well, after the fluid glass 20 deformed to the state shown in FIG. is peeled off, a final modeled object consisting of only the modeled glass 21 is obtained.

FIG. 6 shows a final modeled object 202 of the modeled glass 21 formed according to the second application example. The shape of this modeled object 202 is similar to the modeled object 201 shown in FIG. 4, but the surface of the tip portion of the convex body 5a (the portion joined to the metal plate 11) is flat. Also, different colors appear on the bottom surface of the flange 24a and the tip of the convex body 25a. The former color is due to the first colored layer 3 and the latter color is due to the second colored layer 30 .

In this way, the two metal plates 10 and 11 to be brought into close contact with the fluid glass 20 are made of different kinds of metals, so that the modeled object 202 colored with two kinds of colors can be obtained. The decorative effect can be further enhanced.

FIG. 7 shows a modification of the first application shown in FIG. In this example, by applying the example of FIG. 2, a bowl-shaped metal body 13 having a through hole h in the center is placed on a support base 4 (only the upper surface is shown in this figure) with the open end facing downward. ), and the plate glass 2 is placed on the range including the through hole h, and both are placed in the kiln (Fig. 7(A)).

The lower surface of the plate glass 2 is separated from the metal body 13 not only at the portion corresponding to the through hole h, but also at the edge portion. However, in the glass 20 that has become a viscous fluid by heating, the edge portion and the portion above the through hole h descend due to the action of gravity, and the portion that is in close contact with the curved surface of the metal body 13 outside the through hole h. 26 and a portion 27 hanging down from the through hole h change into a continuous shape (FIG. 7(B)). Further, the colored layer 3 derived from the metal oxide generated at the interface with the metal body 13 is formed on the surface layer portion on the bottom side of the portion 26 that is in close contact with the curved surface.

After that, the fluid glass 20 is cooled to form a shaped glass bonded to the metal body 13, and then the metal body 13 is peeled off from the shaped glass to form a convex body having a concave portion on the brim portion having the colored layer 3. can be obtained in the final form (not shown).

Further, in the example of FIG. 7, the second metal plate 11 is arranged at a place facing the through hole h of the support base 4, and the portion 27 hanging down from the through hole h of the fluid glass 20 is in close contact with the metal plate 11. By deforming the glass 20 until a predetermined time elapses, the tip of the projecting body in the final form can be flattened and the second colored layer can be included in the surface layer.

FIG. 8 shows a modeling method corresponding to a third application example.
In this example, a bowl-shaped metal body 14 (a thin body having a bottomed hole 14a with a curved inner surface) is placed on the support base 4 with the open end facing upward, and the metal body 14 is A circular plate glass 2 having a size that allows the lower edge to be caught in the upper end portion of the hole 14a is supported in a state of being caught in the same portion (FIG. 8(A)).

Heating is started in the kiln while maintaining the above support state. The glass 20, which has been turned into a viscous fluid by heating, descends in order from the central portion due to the action of gravity (FIG. 8(B)), and eventually comes into close contact with the inner surface of the hole 14a of the metal body 14 (FIG. 8 ( C)). If the flow of the glass 20 is continued for a while in this state, the metal oxide generated at the interface between the fluid glass 20 and the metal body 14 and the transition metal ions therein diffuse into the fluid glass 20, resulting in the formation of the glass 20. A colored layer 3 derived from a metal oxide is formed on the surface layer portion of the portion in close contact with the metal body 14 .

FIG. 9 shows an example of a combination of the shaped glass 21 and the metal body 14 produced by cooling the fluid glass 20 in the state of FIG. 8(C). Since the metal body 14 of this embodiment is thin, it can be peeled off from the modeling glass 21 with bare hands or a tool such as pliers to obtain a final shaped object 203 consisting only of the modeling glass 21 .

The outer peripheral surface of the shaping glass 21 exposed by peeling off the metal body 14 becomes a curved surface similar to the inner surface of the hole 14a of the metal body 14, and the colored layer 3 is formed along almost the entire curved surface. A transparent concave surface (corresponding to the portion 28 in FIG. 8(C)) is also formed on the top of the modeling glass 21 by a gently curved surface, and the colored layer 3 is also reflected on the concave surface, making it difficult for the line of sight to see. Interesting that the color tone changes depending on the direction can be obtained.

In the method according to the third application example, a plurality of finely crushed glass pieces are put under the plate glass 2 arranged in the upper part of the bottomed hole 14a of the metal body 14, and these glass pieces are converted into plate glass. 2 to obtain a shaped glass sized to fill substantially the entire space provided by the inner surface of the metal body 14 . By increasing the number of glass pieces or adding larger spherical glass, it is possible to obtain similar shaped glass by fusing a plurality of glass pieces without using the sheet glass 2. - 特許庁
In these shaped glasses as well, the colored layer 3 derived from metal oxide is formed on the surface layer portion of the outer peripheral portion in close contact with the metal body 14 .

In the space under the sheet glass 2 of the metal body 14 in the example of FIG. 8, it is also possible to put a plurality of small pieces of metal together with a plurality of glass pieces. These glass pieces and metal pieces are mixed inside the fluid glass 20, and a colored layer is also formed on the portion of the fluid glass 20 that is in close contact with each metal piece. As a result, in the shaped glass produced by cooling, the color of the colored layer 3 made of the metal body adhered to the outer peripheral portion is used as a base, and the color of the colored layer made of the small pieces of metal is distributed as a pattern in the colored layer 3, resulting in high decorativeness. can be obtained. The small pieces of metal may be made of the same kind of metal material as the metal body 14, but if they are made of a different kind of metal material from the metal body 14, a more attractive pattern can be presented.

The metal bodies used in the third application example and its modifications are not limited to those having bottomed holes. A method similar to that shown in FIG. 8 can be implemented using a combination with a thin metal plate. Alternatively, by placing the cylindrical body containing the glass on the support base without closing the open end face, with the direction of penetration of the hole facing sideways, the same method as shown in FIG. Fluid glass fused from glass pieces can also adhere to the inner surface of the hole.

FIG. 10 shows a modeling method corresponding to a fourth application example.
Also in this embodiment, two types of metal plates 101 and 102 are used as in the second application example. One metal plate 102 is smaller than the other metal plate 101 and has two through holes h1 and h2. The sheet glass 2 has a major surface of approximately the same size and shape as the metal plate 102 .

A metal plate 101 without through holes is placed directly on the support base 4, a metal plate 102 having through holes h1 and h2 is placed thereon, and a plate glass 2 is placed on the metal plate 102. (Fig. 10(A)).

The support table 4, the metal plates 101 and 102, and the plate glass 2 are placed in a kiln while maintaining the above-described positional relationship, and the kiln is heated. The portions arranged on the through-holes h1 and h2 of , enter the holes h1 and h2 and begin to descend (FIG. 10(B)). The portions around the holes h1 and h2 of the fluid glass 20 also follow and move toward the holes h1 and h2, and part of them descends. Eventually, the tip of the lowered portion reaches the metal plate 101 and comes into close contact with the metal plate 101 (FIG. 10(C)).

In the surface layer of the portion of the fluid glass 20 in close contact with the metal plate 102, the metal oxide generated by the close contact with the metal plate 102 and the transition metal ions therein are diffused. is formed. Furthermore, the metal oxide generated by the close contact with the metal plate 101 and the transition metal ions therein are also diffused into the surface layer of the portion that descends from the holes h1 and h2 and is in close contact with the metal plate 101. An accompanying second colored layer 32 is formed.

In the fourth application example, after the fluid glass 20 deformed to the state shown in FIG. By peeling off, a modeled object in the final form is obtained by combining the modeled glass 21 and the metal plate 102 .

FIG. 11(A) shows the final form of the model 204 obtained by peeling off the metal plate 101 after the method shown in FIG. (referred to as the “surface portion”) is shown as the front. FIG. 11(B) shows a portion of the modeled object 204 that is connected to the metal plate 101 (hereinafter referred to as a “rear surface portion”).

The surface portion is covered with the shaping glass 21, and from the glass surface, the first colored layer 31 generated in the portion in close contact with the metal plate 102 and the second colored layer 31 generated in the portion in close contact with the metal plate 101 are formed. Layer 32 can be seen through.

The back surface portion includes the surface of the metal plate 102 and the surfaces of the portions exposed from the through holes h1 and h2 of the modeling glass 21 (the portions in close contact with the metal plate 101). The color of the second colored layer 32 appears on the surface of the modeling glass 21 .

In the fourth application example, instead of the metal plate 102 having the through holes h1 and h2, a metal plate provided with notches at one or several locations on the edge may be used. In this case also, while the fluid glass is made to flow on the surface of the metal plate provided with the notches, part of the fluid glass descends from the notch portion and adheres to the metal plate 101, thereby making the fluid glass adhere to each metal plate. A first and a second colored layer can be formed on the surface layer of the portion to be coated. Furthermore, after the fluid glass is cooled to become the shaped glass to be bonded to each metal plate, the metal plate 101 is peeled off from the shaped glass, thereby forming the first notched metal plate having a shape corresponding to the metal plate. It has a surface part where the color of the colored layer and the second colored layer having a shape corresponding to the notched part appears, and a back part where the second colored layer appears in the notched part of the metal plate with the notch. A model can be obtained.

The metal plate 102 described above can also be changed to a thin metal body with more through-holes. For example, a metal body processed into a grid shape is placed on the metal plate 101, and a plate glass is placed on the metal plate 101 and heated. The second colored layer based on the metal plate 101 is formed in the holes of the lattice pattern by the color of the first colored layer based on the grid-shaped metal body by maintaining the contact state for a while. It is possible to obtain a modeled article having a surface portion with a color appearance. Also on the back side of this modeled object, the color of the second colored layer appears in the holes of the grid-shaped metal body.

Instead of the metal plate 102, a plurality of metal pieces may be arranged on the upper surface of the metal plate 101 with a predetermined space therebetween. In this case as well, by placing the plate glass in the range where the metal pieces are distributed and heating, the glass, which has become a viscous fluid, is adhered to each metal piece while passing through the gaps between them and is also brought into close contact with the metal plate 101 . , colored layers derived from metal oxides generated by the close contact can be formed on the portions of the fluid glass that are in close contact with the metal pieces and in the portions that are in close contact with the metal plate 101 . Furthermore, by peeling off the metal plate 101 from the shaping glass after the deformed fluid glass is cooled and changed into the shaping glass, the color of the colored layer based on the metal plate 101 is revealed on both the front surface and the back surface, A pattern formed by the distribution of a plurality of metal pieces can be formed on the back surface, and a similar pattern can be formed on the surface portion by the color distribution of the colored layer based on the metal pieces.

FIG. 12 shows a modeling method corresponding to a fifth application example.
In this embodiment, a metal body 110 shaped in a form in which rods 112 of a predetermined length are erected from a plurality of positions on the outer periphery of a circular plate portion 111, and a circular plate portion 111 having an area slightly larger than that of the plate portion 111. A plate glass 2 is used.

Each bar 112 is of equal length and approximately the same spacing between each other. The sheet glass 2 is placed on the upper end surface of the bar piece 112 of the metal body 110, thereby being supported so as to face the plate portion 111 (FIG. 12(A)).

When both are placed in a kiln while maintaining the above relationship and heated, the portion of the glass 20 facing the plate portion 111, which has turned into a viscous fluid, begins to descend, and eventually the central portion reaches the plate portion 111 and the surface thereof. becomes in close contact with The portions of the fluid glass 20 protruding outside the rods 112 are also deformed, descending while contacting the upper end surfaces of the rods 112 , and deformed so as to wrap the upper portions of the rods 112 .

According to the above method, the shaped glass 21 produced by cooling the fluid glass 20 has a vessel-like shape having a bottom portion connected to the plate portion 111 and wall portions connected to the rods 112 ( FIG. 12(B)).

The surface of the bottom of the modeling glass 21 becomes flat along with the plate portion 111 , but the outer and inner peripheral surfaces of the wall portions are curved surfaces reflecting the state when the fluid glass 20 was flowing toward the plate portion 111 . Become. In addition, on the surface layer of the portion of the fluid glass 20 in close contact with the plate portion 111 or the rod piece 112, metal oxide particles generated at the interface between that portion and the plate portion 111 or the rod piece 112, respectively, and A colored layer 33 is formed by diffusion of transition metal ions. These colored layers 33 are maintained even after the fluid glass 20 cools down to become the shaped glass 21, and can be seen through from a portion of the shaped glass 21 where no colored layer is formed.

In this embodiment, the combination of the shaped glass 21 and the metal body 110 is used as the shaped object 205 in the final form. However, the plate portion 111 and each bar piece 112 are made independent, and each bar piece 112 can be attached to and detached from the plate portion 111 by inserting each bar piece 112 into a slit provided on the end face of the plate portion 111. In the case of changing to a connected structure, the colored layers 33 formed at the portions where the rods 112 are in close contact are removed by removing the rods 112 from the plate portion 111 after cooling and then peeling them off from the modeling glass 21 as well. It can be made to appear on the outer surface of the shaping glass 21 . The plate 111 can similarly be peeled away from the shaping glass 21 but may remain bonded to the shaping glass 21 .

Various metal bodies used in each of the first to fifth application examples and modifications are metal bodies mainly composed of transition metals such as silver, cobalt, and titanium, in addition to copper and stainless steel as described above. can do. 10 and the metal body 110 in the fifth application example, all of the metal bodies peeled off from the shaping glass 21 are thin, and the surfaces to which the shaping glass 21 is bonded are thin. is larger than the bonding range, even in the peeling operation after being bonded to the shaping glass 21, it can be relatively easily peeled off by gripping the portion not bonded to the shaping glass 21 with a finger or a tool and applying force. be able to.
It should be noted that these metal bodies do not necessarily need to be completely peeled off, and a part of them may be left bonded to the modeling glass 21 .

Since the metal plate 102 of the fourth application example and the metal body 110 of the fifth application example are included in the final modeled object while being bonded to the molding glass 21, these metal bodies have thermal expansion properties due to the glass material. It is desirable to use metals with similar modulus. If the difference in coefficient of thermal expansion between the metal body and the glass material is reduced, the degree of contraction between the two during cooling is also reduced, and the two can be firmly bonded together, so that the shaping glass 21 does not separate from the metal body. can be prevented. In addition, since the distortion of the glass body due to the tensile force and pressing force from the metal part during cooling can be reduced, even if the metal body left in the final form is thick, the shaped glass can be prevented from breaking.

The coefficient of thermal expansion of soda glass, which is the raw material of the plate glass 2 used in each example, is generally in the range of 80×10 ⁻⁷ to 120×10 ⁻⁷ /°C. Stainless steel whose coefficient of thermal expansion falls within this numerical range is considered to be a metal material suitable for the metal plate 102 of the fourth application example and the metal body 111 of the fifth application example.
For example, SUS430 has a coefficient of thermal expansion of 104×10 ⁻⁷ /°C, and SUS410 has a coefficient of thermal expansion of 99×10 ⁻⁷ /°C. It can be said that it is a material.

In the embodiments described so far, the transparent glass body is heated to be deformed and colored. You can also In such a case, a mixed color of the color of the glass and the color of the colored layer 3 can appear.

In the above embodiment, the glass body is arranged on the metal body, and the glass body, which has become a viscous fluid due to heating, is made to flow and deform. can be supported with the surface facing the glass body, and both can be heated. In this case, when the state in which the metal body is in close contact with the fluid glass is maintained for a predetermined period of time, the metal body having the approximate specific gravity of 3 or more tends to enter the inside of the glass body due to the action of gravity. occurs. This force presses and deforms the fluid glass, and a colored layer derived from the metal oxide is formed on the surface layer of the contact portion. Therefore, after the fluid glass cools down to become the shaped glass bonded with the metal body, by peeling off the metal body from the shaped glass, the color based on the colored layer appears on the surface of the shape reflecting the surface shape of the metal body. It is possible to obtain a modeled object made of glass.
