JPH0632043A - Forming method of colored uneven pattern on surface of glass product - Google Patents

Abstract

PURPOSE:To form efficiently an uneven pattern which is close to a decorative method by clinker enamel, by a method wherein after a necessary pattern is drawn on the surface of a glass product by making use of paints, transparent flux is printed over the stuck paints and glazed. CONSTITUTION:A desirous colored pattern 2 is printed on the surface of a glass product G by paints on the market by a screen printing method. Then after transparent flux 1 which has turned into a grain or insect eye pattern is printed by a mesh screen having a fixed size, glazing is performed at a fixed temperature. Consequently, though the same is fused to the product G and a colored uneven pattern is obtained, in the obtained uneven pattern, the uneven pattern close to a decorative method of the clinker enamel comprised of conventional glass grains can be formed. When compared with the decorative method of the clinker enamel, though swelling of the uneven pattern is low, the decorative pattern is clear. Then mass-production is possible and the colored uneven pattern can be expressed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for providing a colored uneven pattern on the surface of glassware such as cups and dishes or glassware such as figurines.

[0002]

2. Description of the Related Art Conventionally, a crinkle enamel oil (commonly known as jam) 4 or ceramic paste paint has been used on the surface of a glass product G to make a design by screen printing or by hand-drawing, and then a colored or colorless crinkle After sprinkling and adhering a low-melting glass 3 having a relatively large particle size called enamel (glass particles: also called crystal ice), baking treatment is performed to melt the surface of the crinkle enamel, and then to the surface of the glass product. A decoration method is used to form an uneven pattern by fusing the crinkle enamel.

By the way, in recent years when it is desired to diversify designs, the number of colors of colored crinkle enamel required for this purpose increases, and it is necessary to prepare and hold various kinds of colored crinkle enamel in advance. However, in reality, commercially available colored crinkle enamel has a smaller number of colors than the number of colors of ceramics paint, and the color tone of the design is greatly restricted, and the required crinkle is regenerated every time this decoration process is performed. On the other hand, it is complicated to buy enamel, but on the other hand, it is not preferable from the standpoint of storage management to prepare and hold various kinds and large quantities of enamel in advance.

Further, in the work, there is no dedicated crinkle enamel sprinkling device, and the work by hand is required. In the case of dampness, the crinkle enamel adheres to the part other than the decorative pattern, and it is very difficult to remove during work.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object thereof is to form a concavo-convex pattern similar to the decoration method of a crinkle enamel and to provide a method with good workability. To provide.

[0006]

The present invention comprises a step of drawing a desired pattern on a surface of a glass product with a paint and a step of printing a transparent flux on the adhered paint and baking it. This is a method for forming a colored uneven pattern on the surface of a glass product.

[0007]

The transparent flux can be used to form an uneven pattern by changing the size of the screen mesh or making the pattern of the screen grainy or worm-like.

[0008]

Example 1 A desired colored pattern 2 was printed on the surface of a glass product G by a screen printing method with a commercially available paint, and a transparent flux 1 S having a grain pattern or an insect pattern on the pattern was printed.
-7000 (Okuno Pharmaceutical Co., Ltd.) 100 or 120
After printing with a mesh screen, bake at about 600 ° C. It was fused to a glass product to obtain a colored uneven pattern. The obtained colored unevenness pattern had an unevenness pattern similar to that of a conventional crinkle enamel decoration method composed of glass particles. Compared to the crinkle enamel decoration method, the uneven pattern rises less.

As the screen, a 100 or 120 mesh screen was used, but an MS-50 film (manufactured by Murakami Screen Co., Ltd.) having an emulsion thickness of 80 μm or 100 μm was attached by the emulsion attaching bucket method to 150 mesh. A screen may be used.

In the present invention, when the unevenness of the colored pattern is roughened, it is achieved by lowering the mesh number of the screen for screen printing, using a grained screen, and increasing the printing thickness. It Further, in order to smooth the unevenness of the colored pattern, it is sufficient to use an insect screen to reverse the above.

[0011]

As described above, according to the method of the present invention, as compared with the conventional decoration method of the crinkle enamel, the protrusion of the uneven pattern is small, but the decorative pattern is clear. Also,
It can be mass-produced and can represent colored uneven patterns.
