TECHNICAL FIELD OF THE INVENTION
The present invention relates to a method for manufacturing and decorating decorative glass and glass bottles, such as door glass, window glass, partition glass, and other decorative glass products used in general buildings and stores, and glass decorative articles such as picture frames, cups, or interior glass products. It is about glass.
In the production of such decorative glass products, a method of processing colored glass corresponding to a pattern classified by color into individual pieces, bonding the colored glass pieces, sealing and manufacturing one piece of decorative glass, In addition, a method has been adopted in which colored glass processed into a predetermined pattern is placed on one glass plate, heated, and the colored glass and the glass plate are melted and joined.
[0002]
[Prior art]
Conventionally, as a decorative glass product, a decorative glass in which various kinds of colored glass such as stained glass are combined is known. In the production of such decorative glass products, a method of individually processing colored glass corresponding to the pattern divided for each color, joining the colored glasses, and sealing to produce one piece of decorative glass, Alternatively, a method has been adopted in which a colored glass processed into a predetermined pattern is placed on a single glass plate, heated, and the colored glass and the glass plate are melted and joined.
[0003]
[Problems to be solved by the invention]
However, the former method has a problem in that it takes time and effort to manufacture, is not suitable for mass production, and requires skill.
[0004]
In addition, the latter method has a problem that cracks and breaks occur at the joint between the glass plate and the colored glass of the finished decorative glass product due to the difference in thermal expansion between the colored glass and the plate glass.
[0005]
For this reason, it is conceivable to adjust the thermal expansion coefficients of the colored glass and the sheet glass to be the same, but it is difficult to produce a colored glass having a uniform thermal expansion coefficient, and it is difficult to use the glass. There is a problem that the limited color glass is limited.
[0006]
The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a decorative glass capable of manufacturing decorative glass products in which various color patterns are arranged without causing cracks or breakage. The purpose is to provide products and their manufacturing methods.
Also, the present invention provides a decorative glass product and a method for manufacturing the same, which can produce decorative glass products having various colored patterns arranged therein without causing cracks or breakage even when sheet glasses having different thermal expansion coefficients are stacked and heated and melted. .

[0014]
In the method of manufacturing decorative glass by overlapping and melting glass sheets having different expansion coefficients to produce a decorative glass, the glass sheets having different expansion coefficients are pulverized, and the pulverized powders are mixed at a predetermined ratio. This is a method of manufacturing decorative glass by dispersing or sticking between sheet glass layers, further attaching a cullet, and heating and melting the sheet glass.

Embodiment
It is a decorative glass in which cullet is inserted between sheet glass layers and the sheet glass is heated and melted.
In addition, the cullet is a luminous body “also referred to as a luminous body” that stores and emits a small amount of ultraviolet light emitted from waste glass, colored glass, the sun, a fluorescent lamp, and the like (for example, the luminous body is manufactured by Musaku Park). Metals, rocks, minerals, slag, and other inorganic substances may be processed into granules or powder.
The cullet to be inserted between the layers includes a method in which the cullet is randomly scattered without using an adhesive, and a method in which an arbitrary design is drawn using an adhesive, and both methods can be applied.
When heated and melted with sandwiched tempered glass sandwiched between laminated glass sheets, tempered glass plywood can be formed, and if you select the shape of the shelf laid under the glass sheet, the shape of a glass tile etc. will be obtained and it will be a building material that changes to pottery Can be manufactured.
[0023]
The surface of the sheet glass to be overlapped is washed with a degreasing agent or the like, a cullet is arranged on the surface, and the cullet is fixed with an adhesive or scattered at random, and then the sheet glass is overlapped and the sheet glass is prepared in advance on the hearth of a ceramic furnace. It is placed on the unglazed pottery and heated and melted to produce decorative glass.
[0024]
When decorative glass is manufactured by laminating and melting glass sheets having different expansion coefficients, the laminated glass sheets in order to avoid cracking and breaking of the glass, i.e., the glass sheets having different expansion coefficients are crushed in advance, and the crushed powder is used. Are mixed at a predetermined ratio. The mixing ratio of the glass material having a large expansion coefficient is large when the expansion coefficient is largely different, and may be 1: 1 when the difference between the expansion coefficients is small, for example, 2: 1. Note that if the glasses have the same composition, they need not be used because they have the same thermal expansion coefficient.
This is a method of producing decorative glass by dispersing or affixing the mixed powder between the glass layers having different coefficients of expansion, attaching a cullet thereto, charging the glass plate into a kiln, and melting by heating.
[0025]
If the upper glass sheet to be overlapped has an area larger than the thickness of the lower glass sheet, the upper extruded glass softens and melts and fuses so as to wrap the lower glass, so a rounded glass end surface is obtained. Can be
[0026]
A decorative glass having a sense of perspective can be manufactured as long as it is a decorative glass in which the cullet is inserted between multiple layers of sheet glass.
[0027]
If the thickness of the upper glass sheet is larger than that of the lower glass sheet, the weight of the upper glass sheet presses the lower glass sheet, so that even if the air between the layers expands, distortion can be suppressed.

However, if the temperature is lower than 700 ° C., the fusion may be insufficient and the joint may be detached during handling. If the temperature is higher than 800 ° C., the viscosity becomes too small to flow, which is not suitable.
Preferably, it is a method for producing decorative glass in which the temperature at which the plate glass is heated and melted is 730 to 770 ° C.
