Method of handmade small decorative glass objects, mostly flat

Technical field

The invention relates to a method of hand-making small decorative glass articles, predominantly flat, e.g., jewelry, flower and tree leaves, and decorative flat edges.

A gas burner and two glass rods are used for the work, one of which is always used for holding and the other for melting. After each working step, the formed article is uniformly heated and after each several steps of remelting the added strands. Possible cooling of the final product depends on its size.

BACKGROUND OF THE INVENTION

X

In the manufacture of small decorative objects from glass rods, glass burners of various designs are used, especially in the combination of natural gas - air or so-called oxygen burners.

The basic types of glass rods sold for this production vary according to the amount of lead oxide the glass contains.

Flat objects are formed from the heated rod in various ways:

• They are shaped by pressing glass tweezers - eg ears of glass animals.

• It is formed by a spirally melted thin rod - eg hollow skirts of glass dolls.

• Squeeze out molds made for this purpose - eg. petals of flowers.

• It is formed by a regularly bent, monolithic “intertwined” strand of glass, eg a boat.

Czech Patent 291 079 discloses a method of manufacture by the laminated glass method of the same Applicant and Applicant as in the present invention.

Gradually, a single strand of glass or so-called aerated strands of glass melts side-by-side, side-by-side or side-by-side, which overlaps wholly or partially on top of each other and / or side by side until a predominantly spatial laminate is formed. pockets and capillaries.

X

X) (

Czech patent d. 291 079 describes in detail a method of manually manufacturing decorative glass articles intended for working with a gas burner and a melting and holding rod, in which remelting and subsequent cooling are carried out after each working operation. The first strand is formed from the glass strand from the 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 is again melted from the melting rod. Gradually, other strands of glass are melted, which overlap completely or partially on top of each other and / or side by side until a layered formation or layered coating is formed, each with aerated pockets.

A strand of glass from the melting rod can be adhered to the substrate, then it is pulled out and bent back off the flame of the gas burner, which is repeated until the glass has cooled. An aerated glass strand with air pockets and capillaries is formed during repeated bending and extraction. 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 aerated glass strands are melted, which are completely or partially superimposed on each other and / or adjacent to each other until a laminate or layered coating is formed, each with aerated pockets.

The glass strand from the melting rod can also be pulled out after being glued to the substrate and the melting rod melted therefrom, thereby forming a single strand on the substrate. Subsequently, another simple strand of glass is melted next to, on or into it, partially or completely, which is again melted from the melting rod. Gradually, other simple strands of glass are melted, which overlap completely or partially on top of each other and / or side by side until a layered formation or layered coating is formed, each with aerated pockets.

The base is a holding rod, possibly a glass smooth surface, or already formed layered formations or layered covering.

The layered formations may be spatial formations or predominantly flat formations.

Each new additional strand of glass may be sealed with the preceding portion while maintaining air pockets or capillaries.

Production of these shapes according to the Czech patent. 291 079 is very decorative, but the intentional layering of strands so that the resulting shape is full of air pockets or aerated capillaries is very demanding on the amount of repetitive movements required

«<

The artist and thus the physical work as well as the consumption of time and material for production. Accurately attaching such laminated glass to small objects, such as the creation of decorative edges of jewelry, is difficult, because if this formation contains a large number of air pockets, capillaries or aerated strands of glass, it gains a volume in which it is difficult to accurately connect to smooth base small formation.

SUMMARY OF THE INVENTION

The above-mentioned disadvantages are overcome or substantially reduced by the method according to the invention, which consists in the fact that the production of a predominantly flat small glass article is carried out by the granular glass method. SUMMARY OF THE INVENTION The present invention is characterized in that non-sealed glass strands are melted onto a smooth glass center or holding rod successively into a planar formation and subsequently melted into sealed glass strands to form a base of sealed glass strands. Next to them, or partially into them, other non-sealed strands of glass melt, which melts from the melting rod. Subsequent melting will result in further sealed glass strands, onto which other non-sealed strands of glass are melted side by side or partially onto and into each other. These further non-sealed glass strands are subsequently sealed again, thereby forming additional sealed glass strands. The gradual melting of other non-sealed glass strands and their subsequent sealing into other sealed glass strands is carried out until they are sufficiently bonded, while maintaining a granular structure, and is repeatedly carried out in a largely general sense until forming a predominantly flat granular glass formation in which the glass strands are sealed separated by clear visual boundaries between the individual grains of the glass and possibly also the spaces between the grains. A thin, open-grained, predominantly flat formation is formed, but it is sufficiently strong and in which the completely non-molten boundaries between individual grains of glass reflect decorative refractions of light.

This gives a decorative flat shape with a predefined shape and a grainy appearance, with the majority of the obtained surface not having aerated pockets. The decorative appearance is sufficiently ensured even without air pockets by reflecting light from individual melted parts which are not sealed into a monolayer, but only so as to maintain as clearly as possible a clearly visible boundary between the parts to be joined.

The final shape is made up of molten strands of glass, sometimes with gaps.

By the method of the present invention, a tiny glass article, predominantly flat, of predetermined arbitrary shape, can be obtained which, by its decorative nature, competes with laminated articles, but is simpler, faster and less

t * demanding on physical work and material. The surfaces thus obtained look more fragile and better and, with greater accuracy, connect to any other piece of jewelry, sheet, etc.

The thus obtained predominantly small glass sheet allows greater accuracy in shaping and connection to small glass objects than laminated glass and is less material, time and physically demanding. It can be combined with smooth or laminated glass to create an impressive decorative effect. For example, instead of bonding the surface to the smooth object, the glass is used for maximum accuracy and the glass in the central part of the flat object then gives the impression of fragility of the object, while the outer edges of the surface are thickened and covered with aerated laminated glass pockets.

The decorative object gives a softer and more delicate impression than if only the laminated glass method was used from the beginning.

It is also possible to combine strands of glass of different colors in this production by means of a grain glass method, thereby obtaining interesting color effects in the final product, and the individual parts of the object created by this method can also be glued into larger units without visible joint.

X The holding and melting rods are used in the production, when a glass formation (eg smooth jewelry center) is glued to the holding rod or the holding rod serves as a glass base itself, from which the grained glass surfaces are created (eg center line during sheet production) .

The functional end of the holding rod should be kept away from the burner flame or its mouth at a distance such that the glass still adheres, but at the same time the individual strands being added to each other only adhere to one another and do not glow into a uniform surface.

The functional end of the melting rod must be heated to a temperature such that a thin strand of glass can be pulled out of the rod and adhered to the heated formation on the holding rod or to the heated end of the holding rod itself. The melting rod is heated, with the heated end attached to the heated base on the holding rod (the base may be a surface of already glued or partially alloyed strands of glass or the center of a jewel or sheet). On this foundation, the rod is glued and drawn back to pull out a thin strand of glass, one end of which remains glued to the foundation and the other end melts away from the melting rod. For each new strand to be formed, the melting rod must be reheated.

The formed flat formation on the retaining rod is constantly heated during the work

X by rotating the retaining rod at an appropriate distance from the burner flame. After several repetitive gluing of other strands, the formation is always resealed, ie it becomes so warm that the glued strands are partially sealed, but only so that they do not fully adhere and their boundaries remain as clear as possible. When sealed, the newly created surface can be bent or pulled with glass tweezers as needed.

For a perfectly decorative appearance of the surface to be formed, it is advantageous that the melting bar used is first pulled out and adequately thinned. From the reasonably thin melting rod the drawn strands are smaller, then they are more numerous on the created area and the area is more granular and thus more decorative.

From too thin a melting rod, the thin strands make the surface too brittle and, when subsequently melted, easily blend into a uniform surface from which the desired decorative light refractions disappear. The wider strands of glass formed by the bulk melting rod give the impression of an unforgiving impression in the surface and the resulting decorative effect is lower.

For a better decorative appearance of the article it is also advantageous if the strands shrink in the direction from the center of the formation to its edges.

The finished, predominantly flat beverage is reheated evenly and slowly cooled.

Larger units without visible and disturbing joints can be glued from such obtained formations.

Examples of the embodiment of the invention

Example 1 (Figures 1 to 8)

In order to obtain a decorative surface of the granular glass 5, the following procedure is followed. A glass holding rod 2 is prepared from a glass melting rod 2. The melting rod 2 should be reasonably thin, since the thinner the smaller the non-fused glass strands 3 are drawn out of it and the surface of the grain glass 5 formed by melting them into the fused glass strands 4 is more granular and decorative. If, however, the non-sealed glass strands 3 are too thin, they are sealed to form a uniform surface which does not contain the desired decorative light refractions. If the diameter of the melting rod 2 is too large, the strands A jb of the non-sealed glass formed are larger and, after melting, the grain glass surface 5 is awkward and the overall decorative impression is less.

The functional end of the holding rod, even with a rotating motion about its longitudinal axis in the burner flame, only warms up evenly so that the glass begins to stick. The functional end of the melting rod 2 must be heated before each withdrawal of the non-sealed glass strand 3 so that its glass can change shape and adhere to the holding rod 7 (Fig. 1). A non-sealed strand 3 of glass is pulled from the melting rod 2 and melted, which remains adhered to the holding rod 1 (FIG. 2) and is then sealed to form a sealed glass strand 4 on the holding rod 1 (FIG. 3).

Further non-sealed glass strands 3 are glued, drawn and melted from the melting rod 2 to the molten glass strand 4 on the holding rod 1 in a largely planar direction, which is then melted into the molten glass strands 4 so that they do not completely blend together /giant. 5). Again, these non-sealed glass strands 3 are adhered to the sealed glass strands 4 in the predominantly planar direction from the melting rod 2, drawn and melted (FIG. 6). These non-sealed glass strands 3 are then remelted into the sealed glass strands 4 so that the non-sealed glass strands 3 merely partially blend with the already sealed glass strands 4, and the boundaries between the individual grains formed remain as clear as possible.

In this way, the surface of the granular glass 5 (FIG. 7) is gradually formed until the desired shape of the predominantly flat granular glass structure 5 (FIG. 8) is achieved. In this grain glass formation 5 there may be gaps between the sealed strands 4 of the grain forming glass. Most of the grain structure contains no air pockets and capillaries. If there are occasionally some aerated pockets or capillaries, it is the result of inattention, not intention.

The functional end of the holding rod, even with the predominantly flat grain glass structure 5, is uniformly heated throughout the work. The resulting predominantly flat grain glass structure 5 can be bent and extracted after heating, and the melting rods 2 of different colors can be combined to form interesting decorative effects. The resulting product is evenly heated and then slowly cooled.

Example 2 (Figures 9 to 24)

In this exemplary embodiment, a smooth glass jewelry 6 made of smooth glass and a decorative edge combined of granular glass 5 and laminated glass 10 (Figs. 23, 24) is described using a smooth glass holding bar 6 and a melting bar 2. made of glass. The smooth center 6 of the glass on the holding rod 1 is always heated between the steps by rotating the holding rod 1 about its longitudinal axis and is maintained at a temperature at which the glass begins to adhere. The same rules as in Example 1 above apply to the heating and volume of the melting rod.

The heated melting rod 2 is adhered to the smooth center 6 of the glass (FIG. 9). A non-sealed strand 3 of glass is pulled out and melted from the melting rod 2 (Fig. 10). On the opposite side of the smooth glass center 6, another non-sealed glass strand 3 is glued (Fig. 11) and continue until the free end of the smooth glass center 6 is longitudinally circled by the non-sealed glass.

2) strands 3 of glass. There may or may not be a gap between the individual non-sealed glass strands 3. Non-sealed glass strands 3 are remelted to form an unfinished row of 7 sealed glass strands 4 (FIG. 12).

Another holding rod 8 (FIG. 13) is melted to the free end of the smooth glass center 6 with the sealed strands 4 of the glass and the original holding rod I is melted (FIG. 14). The loose end f and the smooth center 6 of the formation is encircled by non-sealed strands 3 of glass which are remelted to form a finished row 9 of sealed strands 4 of glass (Fig. 15). A non-sealed strand 3 of glass is melted from the melting rod 2 to the finished row 9 of sealed glass strands 4 (Fig. // 16). - Further non-sealed strands 3 of glass are melted in a predominantly flat direction to the finished row 9 sealed strands of glass. which is remelted to sealed strands 4 of glass

3 $ were only partially cast and the boundaries between the individual glass grains remained as clear as possible (Fig. 18). This process is repeated until the predominantly flat granular glass structure 5 of the desired final shape is obtained at the free end of the smooth center 6 (FIG. 19) by melting more and more strands. For a better final appearance of the jewel, it is preferable that the strands decrease from the smooth center 6 of the formation to its edge. To achieve

of the desired shape of the flat granular glass structure 5, it is necessary to fuse the retaining rod 6 to the free end of the smooth center 6 with the finished grain glass edge 5 and to melt another retaining rod 8 (Fig. 20) thereby freeing the other end of the smooth center 6 of glass 5 (Fig. 21). The strands of laminated glass 10 (Fig. 22) with aerated pockets are gradually melted into the peripheral portion of this grain glass surface 5 by means of a melting rod 2 to form a smooth center piece 6 and an edge combined from the surface of grain glass 5 and laminated glass 10 ( 23 and 24).

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.

Industrial applicability

Grain glass can be used primarily as a decorative accessory to studio glass and in commercial glass production such as stylized decorative cards, flowers, jewelry and Christmas decorations, etc.
