Abstract

The proposed manual fabrication of decorative glass articles is characterized in that a first strand (5a, 5b) is formed from a glass strand (3) of a melting-off glass rod (2). After said first strand (5a, 5b) is processed the melting-off glass rod (2) is welded away therefrom, whereby next to it or partially or completely therein another glass strand (5a, 5b) is welded on. This second glass strand (5a, 5b) is then again welded away from the melting-off rod (2) and other glass strands (5a, 5b) are successively welded on. These glass strands (5a, 5b) are put in layers partially or completely over or next to each other until a layered formation (5, 6), optionally layered coverage (10) with aerated pockets is formed.

Description

Method of hand-making decorative glass objects

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manually producing decorative glass articles for use with a gas burner. The deposition and holding rods are used. After each working operation, remelting and subsequent cooling is carried out.

BACKGROUND OF THE INVENTION

It is known to manually wind glass from sticks or tubes on a glass burner to obtain small decorative glass objects, such as animals, dolls, and the like. Different types of enamel can be used for production, depending on the final product.

Various types of burners are used to heat the glass, whose construction varies according to the type of fuel gas used. Recently, natural gas burners have prevailed. ’

The basic tasks include preheating and cutting glass tubes or rods, edge shaping, melting and melting tubes or rods, side fusion, tube or rod bending, etc.

Small glass objects, such as figurines or beads, are obtained from glass rods. zv winding. The figures are formed by winding the glass from the heated melting rod to the holding rod. For their shaping is used on the one hand the movement of the wound glass itself when bending the holding rod and on the other hand other aids, eg glass tweezers. In the production of beads, the strand of the heated melting rod is wound, for example, in the form of a wire ball, from which the finished beads are removed after the glass has cooled.

Glass objects can also be decorated with the so-called. torn method.

For spatial objects such as figurine heads or animals with a thin strand of glass from a heated melting rod, they emboss embossing in the form of ripples that are sealed into a substrate without air cracks or air pockets, which, if accidentally occasionally appear, are considered a flaw in the technique design.

A thin strand of glass is melted onto the glass substrate

from a heated molten glass rod as follows. The substrate is rotated on the retaining rod, a heated molten glass rod is adhered thereto, and a thin strand of glass is pulled out of it, which is again adhered to the substrate, withdrawn and adhered again. The bonding points are randomly spaced from each other and joined together by glass thread. In forming some doll sleeves, a strand of glass is glued without interruption to the doll's arm at randomly spaced locations joined by the glass yarn so that the glass threads stacked in different directions form a balloon-like sleeve. After sealing, a portion of the threads are sintered, creating air pockets and depressions in the sleeve that look very decorative. In this way of working, however, it is not possible to create a precisely shaped object. The trickle of glass is glued continuously to the substrate gradually around its perimeter and winds it. Thus, it proceeds circumferentially, e.g. in a horizontal direction along the skirt, and is spaced with a single strand of respect, with the glass thread its surface. After the melting rod has cooled, the strand melts, the rod is reheated, and the process is repeated until a layer of overlapping glass yarns is applied to the substrate. Finally, the finished product is sealed in such a way that the individual strands do not become too much together. The resulting surface is embossed with a weave of glass threads. This decoration is decorative, but the applied layer may be irregular with numerous depressions and sometimes bare spots and the placement of the glass threads may be inaccurate.

It is an object of the present invention to provide a decorative glass article having a predefined shape.

SUMMARY OF THE INVENTION

These disadvantages are eliminated or substantially reduced by the method of hand-making the decorative glass articles according to the invention, which comprises forming a first strand from a strand of glass from a melting rod, after which the melting rod is melted from it. Subsequently, another glass strand is melted next to, on or into it, partially or completely, which again melts from the melting rod. Gradually, other strands of glass are melted, which overlay or overlap each other, and / or next to each other, until a layered formation is formed. · 9 · 9 · 9 · 9 Or layered cover, always with aerated pockets.

The main advantage of the present invention is to obtain a novel non-traditional decorative item formed from layers of strands of glass with air pockets or capillaries that cause decorative refraction of light. It is possible to imitate the artwork even in details, it is possible to precisely shape the design for small jewelry, where the combination of smooth and laminated glass looks very decorative. It is possible to produce flat thin objects perfectly shaped, sufficiently strong even without the underlying glass. Individual parts of the object created by this method can be glued to larger units without visible connection.

It is preferred that the strand of glass from the melting rod is adhered to the substrate, then it is pulled out of the burner flame and bent and glued back as close as possible to the original bonding point, which is repeated until the glass has cooled. During this repeated bending and pulling, t. aerated trickle of glass with air pockets and capillaries. After it has been made, the melting rod is melted from it and then, next to, on or into it, partially or completely melted another aerated strand of glass, which again melts away from the melting rod. Gradually, other strands of glass are melted and overlaid. wholly or partially on top of each other and / or side by side until a layered formation of possible layered coverage is formed, each with aerated pockets and capillaries. The aerated trickle of glass is very demanding in terms of production, is very decorative, shimmering and is suitable for spatial and very complex formations such as tree crowns, etc.

It is also advantageous if the strand of glass from the melting rod is adhered to the substrate, then it is pulled out, the melting rod is melted therefrom, thereby forming on the substrate t. simple trickle. Thereafter, a further single strand of glass is melted next to it, onto or into it, again melting away from the melting rod, and gradually melts further single strands of glass which overlap completely or partially on top of each other and / or side by side until a layered formation is formed, possibly with a layered coating, always with aerated pockets. A simple trickle of glass is not so demanding in terms of production, but it is not as decorative as compared to an aerated trickle. Simple strand is especially suitable for mostly thin flat formations or precise decoration of small jewelry and smooth cover

glass surface.

Glass strands aerated or simple can be freely combined.

The functional end of the melting rod must initially be heated to a temperature such that a glass strand can be pulled out of it. The functional part of the holding rod with the object to be formed is kept at a temperature such that the glass does not stick because it is the substrate for forming and layering other strands and at a temperature such that the formed pockets do not flow into a uniform mass with bubbles. The holding rod serves initially as a working substrate, but later only as a gripping element to guarantee a safe working distance from the burner flame. The holding rod, or even the melting rod, is rotated as needed when forming strands. Each new strand is formed on a single heating up of the melting rod and fuses with the already formed portion while maintaining the air pockets, thereby ensuring the strength of the formation or coverage while at the same time achieving visually one whole.

The substrate may be either a holding rod that is suitable for most jobs, or a glass smooth surface such as a glass rod, a ball or the like, or it may be already formed laminates or laminates to give a larger object or surface.

The layered formations may be spatial formations suitable for multidimensional objects such as tree crowns or predominantly flat formations intended for the manufacture of jewelry, tree leaves, and the like.

Examples

Example 1 (Figures 1 to 10)

In order to obtain a decorative glass spatial object, for example a tree crown, a glass holding rod 1 and a glass melting rod 2 are prepared. One end of the holding rod 1 is heated above the burner flame for further processing as the underlying working material. Next, one end of the melting rod 2 is heated over the flame of the burner, and after heating, this end is adhered to the heated surface of the holding rod 1. Subsequently, a glass strand 2 is pulled out of the melting rod 2 (Fig. 1). back to the starting point on the heated surface of the retaining bar 1 (Fig. 2). Subsequently, the heated end of the holding rod 1 is again adhered and the next strand of glass is withdrawn again, while with this new strand 3 the part of the strand 2 of the previous glass is also pulled out, which is aerated by forming air pockets 4 and air capillaries into the first aerated strand 5a. Fig. 3). This process is repeated outside the burner flame until the glass of the first aerated strand 5a has cooled to such an extent that it no longer sticks or bends (FIG. 4).

With each further bending and withdrawing of the aerated strand 5a at the same location, the number of air pockets 4, some of which are glass-filled and drawn into miniature air capillaries, increases. Air pockets on the one hand inside the aerated trickle on the other.

The obtained aerated strand 5a, its free solidified end is twisted and fused to the aerated strand 5a (Fig. 5), and the strand 2 of glass is melted together with the melting

The first finished aerated strand 5a will remain on the holding rod 1 (Fig. 7).

The melting rod 2 is reheated and proceeds as described, except that the melting rod 2 is not applied to the holding rod 1, but directly to the aeration strand 5a formed (FIG. 8),

In the same manner, a second aerated strand 5a (FIG. 9) is formed on the first aerated strand 5a (FIG. 9), which, after making it, is drawn through the flame of a glass burner so as to engage securely with the first aerated strand 5a. however, only to prevent the disposal of air pockets and capillaries.

To one of the aerated strands 5a thus formed or optionally at any point of the aerated strands 5a. further aerated strands 5a (FIG. 10) are formed by stacking side-by-side and stacked in space in all directions. The process described above is continued until the desired design of the final layered spatial formation has been formed partially and reheated, the remainder of the original rods 2 (FIG. 6) for the most part.

6, eg a tree crown (Fig. 10).

Upon completion of this layered spatial formation 6, the melting rod 2 is melted, and the spatial formation 6 on the holding rod 1 can be cooled by slow cooling. After safe cooling, the retaining rod 1 is removed. This creates a spatial tree crown with an impressive decorative look.

Example 2 (Figures 11 to 22)

In this exemplary embodiment, a part of a glass jewel in the form of a butterfly wing (FIG. 20) is described which is made on a glass massive support part 7 on which a laminated flat structure 8 of aerated strands of glass 5a is formed in a predominantly horizontal direction.

The glass strand 3 of the melting rod 2 is glued to the holding rod 1 (Fig. 11), then bent and returned (Fig. 12), again with the original strand 3 of glass is pulled out and returned (Fig. 13). so that an aerated strand of glass 5a with an air pocket 4 and air capillaries is formed. This process is repeated off the burner flame until further air pockets 4 and capillaries are formed until the aerated strand 5a cools and solidifies to a point where it is no longer possible to bend (Fig. 14), and then the melting rod melts after re-heating. 2. (Fig. 15).

A first aerated strand 5a (FIG. 15) is formed on the holding rod 1 as described above, a second aerated strand 5a (FIG. 16) is formed next to it, a third aerated strand 5a (FIG. 17) is formed next to it, and these aerated strands 5a becomes the first row of aerated strands 5a, on the outer periphery of which a further row of aerated strands 5a is formed in a fan-like manner (Fig. 18). On these finished aerated strands 5a, additional aerated strands 5a are fused as a substrate, thereby creating a fan-shaped surface of a plurality of layers of aerated strands 5a (FIG. 19), which may partially or completely overlap.

Each additional aerated strand 5a formed is carefully sealed with the already completed aerated strands 5a so that the capillary air pockets 4 are retained to a greater extent, while the individual aerated strands 5a are joined and give the impression of one piece. With this fusion, the glass tweezers can also be used to pull them into the desired shape.

Further aerated strands 5a are formed until the desired design of one butterfly wing on the holding rod 1 is achieved (FIG. 20). The finished butterfly wing is melted again so that the air pockets 4 with the capillaries are retained. On the opposite finished side of the butterfly wing, a new holding rod 1 '(FIG. 21) is melted as a gripping means and the original holding rod 1 is melted (FIG. 22) so that its remaining part forms a massive support part 7 (FIG. 22). . The first half of the butterfly wing can be cooled after careful melting, while maintaining the air pockets 4 and capillaries. By this method a thin shimmering surface can be formed without any substrate.

Example 3 (Figures 23 to 31)

The melting rod 2 is glued to the holding rod 1 and the short strand 2 of glass is pulled out (Fig. 23). The melting rod 2 is melted away from the glass strand 3, leaving a single strand 5b (Fig. 24) on the holding rod, next to which another simple strand 5b of glass (Fig. 25) is melted onto the holding rod. rod 2 (Fig. 26). The other single strands of glass 5b are fused side by side in a plane which forms the base for adhering another single strand of glass 5b (Fig. 27) so as to form a fan-shaped surface from single strands of glass 5b melted even partially over each other (Fig. 28) This results in air pockets 4. The thin single strands of glass 5b are used because the thinner the single strands 5b are thinner and the more layers are deposited, the more glittering the surface. The thin single strands of glass 5b are stacked on top of one another or side by side to form a layered substantially flat structure 8. These single strands 5b are subsequently melted to join into a single layered flat structure 8 while maintaining the air pockets 4. In this melting process the obtained layered substantially flat structure 8 can be further drawn with the glass tweezers into the desired shape. These simple strands 5b are fused by this process until one finished butterfly wing (FIG. 29) is obtained on the holding rod 1. The entire layered substantially flat structure 8 is sealed. A second retaining rod 1 'fits to the opposite side of the butterfly wing to the opposite side of the butterfly wing (fig. 30) and the original retaining rod 1 melts away (Fig. 31). The finished layered flat structure 8 is again melted gently while maintaining the air pockets 4 and can be cooled. The retaining rod 1 'is then removed.

In this way, a shimmering surface is formed without a substrate. The finished product looks very soft and fragile, but is still strong enough.

Example 4 (Fig. 32)

On the flower stem (Fig. 32) it is suitable to use the procedure described in the previous example 3, where the glass smooth surface 9 of the support rod is covered with several layers of short single strands of glass 5b side by side, partially on top of one another. without capillaries. During operation, the single strands 5b need to be melted to provide a regular coverage of the glass smooth surface 9 of the support rod while maintaining the air pockets 4. The single strand 5b can be melted at one location after each step and fill any irregularities of the smooth surface 10 Glass support rods. The result is a dense layered shimmering coverage 10 without significant holes or bare spots. Of course, the resulting layered coating 10 on the smooth surface 2 of the support rod is carefully heated due to the air pockets 4 and then cooled.

Example 5 (Fig. 33)

By the process with the aerated glass strands 5a described in the embodiment 1 and 2, a similar layered coating 10 can be obtained on the smooth surface 9 of the glass support rod (FIG. 33) described in the previous embodiment 4 but which is, in contrast to 4, capillaries. and and more decorative.

Example (Fig. 34)

By way of illustration, the directions 11 of the deposition of the deposition rod 2 in the formation of the aerated strand 5a of the laminated spatial formation 6 are shown in Fig. 34, which shows that the deposition rod 2 moves in all directions and returns as far as possible same place.

Example 7 (Fig. 35)

By way of illustration, the directions 11 of the deposition of the deposition rod 2 in the formation of the aerated strand 5a of the layered and predominantly flat formation 8 shown in FIG. 35 show that the deposition rod 2 is only partially returned and the aerated strand 5a in only one direction.

The foregoing examples do not limit other possible combinations and process variants within the scope of the claims of the invention and within the spirit of the invention.
