Abstract

PROBLEM TO BE SOLVED: To attain an excellent effect in varieties as a mosaic by an arrangement of glass pieces of which the shapes and the colors are different by a method wherein on the total surfaces or one surface of an irregular glass piece, a glaze which melts at the melting temperature or lower of the corner parts is applied, and after heating the glass piece to the melting temperature, the glass piece is cooled. SOLUTION: On the total surfaces or one surface of an irregular glass piece 1, a glaze which melts at the melting temperature or lower of the corner parts of the glass piece 1, is applied, and after heating the glass piece 1 to the melting temperature, the glass piece 1 is cooled. Thus, the glass piece 1 is placed under a state wherein only the corner parts are molten and rounded while keeping the overall shape, and it is safe even when being touched by hand, and at the same time, glass pieces of various shapes can be formed, and also, by using various glazes of which the color developments are different, there is an effect wherein by an arrangement of the glass pieces 1 with different shapes and colors, the interest as a mosaic is excellent. Also, mosaic pieces for which desired colorings are applied, and which have transparent feel, and a beautiful appearance different from mosaic pieces made of ceramic can be manufactured.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing glass mosaic pieces for decorating floors and walls of buildings using broken glass such as broken beer bottles.

[0002]

2. Description of the Related Art
Most of the glass waste is landfilled as waste, and some of it is used as mosaic pieces.However, the manufacturing method is to crush the glass waste into powder, mix it with other raw materials, and press-mold. The post-firing process not only complicates the process and increases the cost, but also has a problem that the arrangement as a mosaic is not interesting because the shape is fixed.

[0003]

Means for Solving the Problems, Means and Effects As a means for solving such problems, the invention of claim 1 is directed to a method of forming a glass piece having an irregular shape on the entire surface or on one surface thereof at a melting temperature of a corner of the glass piece. A glaze that melts at the following temperature is applied, and the glass piece is heated to the melting temperature and then cooled, and only the corners are melted while maintaining the shape of the glass piece as a whole. Because it is rounded, it is safe to touch with your hands, it can be made in various shapes, and by using various glazes with different colors, the arrangement of glass pieces with different shapes and colors There is an effect that the mosaic is interesting, and the invention of claim 2 heats the glass pieces by placing them in a sagger covered with powder that does not melt at the melting temperature of glass such as alumina. Ik pieces not only there is no fear of fusing the sagger, there is an effect that can be stuck firmly to the substrate becomes lower surface rough surface corresponding to the sagger mosaic pieces.

Further, according to the present invention, it is possible to produce a mosaic piece having a desired appearance and a transparent feeling, which has a different appearance from a ceramic mosaic piece.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an irregularly broken glass piece.
It has sharp and sharp corners.

FIG. 2 shows a state where the glaze 2 is applied to one surface of the glass piece 1 with a brush a.

The glaze 2 needs to be melted at a temperature lower than the temperature at which only the corners of the glass piece 1 melt and become round (about 850 to 900 ° C., depending on the components of the glass piece 1).

In FIG. 2, one side of the glass piece 1 is coated with a glaze by brushing to leave a peripheral portion thereof, thereby obtaining a mosaic piece with a border.
Glaze may be applied to the entire surface by spray coating, or glaze may be applied to the entire surface of the glass piece.

FIG. 3 shows a state before heating, in which a glass piece 1 coated with glaze is placed in a sagger b before heating, and alumina powder 3 is spread on the bottom of the sagger b.

FIGS. 4 and 5 show a mosaic piece 4 produced by placing the container in a furnace (not shown) together with the sagger b and then heating and cooling the glass. It is in a baked state.

In the present embodiment, since the alumina powder is spread on the sagger b, welding is prevented, and
The back surface is rough and can be firmly attached to the substrate during construction.

[Brief description of the drawings]

FIG. 1 is a perspective view of an example of a glass piece used for carrying out the present invention.

FIG. 2 is a perspective view of a state in which glaze is applied to the glass piece.

FIG. 3 is a cross-sectional view of a state in which a glass piece coated with glaze is placed in a sagger.

FIG. 4 is an enlarged sectional view of a mosaic piece manufactured in a sagger, heated and cooled.

FIG. 5 is a perspective view of the mosaic piece.
