Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for applying a colored uneven pattern to the surface of glassware such as cups and plates, or glass products such as ornaments, and to a crinkle enamel used therein.

Conventionally, designs are applied to the surface of glass products by screen printing or hand-painting using crinkle enamel oil (commonly known as jam) or ceramic paste paint, and then colored or colorless crinkle enamel (glass grains: crystal ice) is applied onto the surface of the glass product by screen printing or hand-painting. By sprinkling and adhering low-melting glass with a relatively large particle size (also referred to as glass), a baking process is performed to melt the surface of the crinkle enamel and fuse the crinkle enamel to the surface of the glass product. A decorative method that creates uneven patterns is being used.

Nowadays, it is desired to diversify designs, and the number of colors of colored crinkle enamel required for this purpose has increased, and it is necessary to prepare and stock many types of colored crinkle enamel in advance. In reality, commercially available colored crinkle enamels have a smaller number of colors compared to the number of colors for ceramic paints, and the color tone of the design is severely restricted.In addition, the necessary amount of crinkle enamel must be purchased each time this decorative treatment is performed. On the one hand, it is troublesome to have to do this, and on the other hand, it is not desirable from the standpoint of storage management, etc., to prepare and store a large number of different types and quantities in advance.

The present invention has been made to solve these problems, and one of its purposes is to easily prepare crinkle enamel in the required color and amount in the required amount prior to decorative treatment. It's all about making it possible.

That is, the present invention provides a crinkle enamel whose surface is coated with paint by mixing the crinkle enamel with a ceramic paste paint consisting of a mixture of pigment, frit (flux), and squeegee oil, and then drying the mixture. This is one of its characteristics.

Another object of the present invention is to use crinkle enamel colored with such paint,
The purpose is to form a colored uneven pattern on the surface of glass products.

That is, another feature of the present invention is that using crinkle enamel oil, squeegee oil containing frit dispersed therein, or ceramic paste paint,
To provide a method for forming a colored uneven pattern by applying a pattern to the surface of a glass product by a screen printing method, sprinkling crinkle enamel coated with the paint onto the pattern to adhere it, and then baking the pattern. There is a particular thing.

The present invention uses a generally commercially available precious metal paste liquid (basically consisting of a colloidal precious metal resin compound (noble metal balsam) and a vehicle) as a ceramic paint, and mixes this with crinkle enamel. By drying, a crinkle enamel is produced whose surface is coated with a precious metal salt, and after being sprinkled onto the surface of a glass product in the same manner as above, the crinkle enamel is baked to create the metallic luster and luster characteristic of precious metals. It should be noted that this does not exclude the formation of a colored uneven pattern.

Therefore, the gist of the present invention is to mix crinkle enamel with a ceramic paste paint (including the case of a precious metal paste liquid) consisting of a pigment frit and squeegee oil, and then dry it to form a crinkle enamel whose surface is coated with the paint. There is also oil for crinkle enamel on the surface of glass products,
drawing the desired design using either frit-containing squeegee oil or paste paint; depositing crinkle enamel on the design, the surface of which is coated with ceramic paste paint; and applying the applied crinkle enamel to glass. A method for forming a colored uneven pattern on the surface of a glass product, comprising a step of baking the product.

According to the present invention having such a configuration, conventional colored crinkle enamel (colored glass particles) has a limited variety of colors, so it can be used to create glassware such as cups, plates, etc., or ornaments. In contrast, the crinkle enamel according to the present invention has the ability to coat the crinkle enamel as colorless and transparent glass particles with an appropriate colored paint. There is an advantage that there is virtually no restriction on the type of color depending on the color, and
Because colored crinkle enamel is easy to manufacture, you can adjust and prepare just the amount you need when you need it, and it is inexpensive and has benefits in terms of storage management. is also extremely large.

In addition, the glass particles referred to as crinkle enamel in this specification mainly have a single particle size of 30 to 100 mesh, or are composed of a mixture of particle sizes of 30 to 100 mesh. say something

Hereinafter, the present invention will be explained based on embodiments shown in the drawings.

Example 1 A glass powder frit having a relatively low melting point and a mixture of a green inorganic pigment were added to squeegee oil for ceramic paints and mixed well to prepare a paste-like paint. Next, colorless glass particles 2 (crinkle enamel) were gradually added and mixed with stirring, and then heated at about 100°C for about 15 minutes to dry the paint covering the surface of the crinkle enamel, and green inorganic pigment was added. A colored crinkle enamel 1, shown in FIG. 1, coated with and frit was prepared. Note that 3 in the figure indicates a paint coating layer.

Next, in FIG. 2, on the surface of glass product G,
A pattern 4 was printed using oil for crinkle enamel by a screen printing method (FIG. 2a), and the above-described crinkle enamel 1 was sprinkled onto the pattern 4 to adhere (FIG. 2b).

Next, this was baked at about 580° C. by a conventional method to fuse the crinkle enamel 1 together with the frit to the surface of the glass product G, thereby obtaining a green uneven pattern 5 (FIG. 1c). The obtained green colored uneven pattern 5 was almost the same as seen with the naked eye compared to a similar pattern made using crinkle enamel made of green glass particles using a conventional method.

Example 2 A crinkle enamel 6 coated with a red inorganic pigment and frit was produced by the same method as in Example 1. Next, as shown in Fig. 3a, a pattern 4' of paste made by mixing frit with squeegee oil was printed on the surface of the glass product G by screen printing method, and crinkle enamel 6 was sprinkled on it to adhere it (Fig. 3a). After b), the crinkle enamel 6 was fused to the surface of the glass product G together with the frit and the pigment by baking at about 580° C. by a conventional method to obtain a red uneven pattern 7 (FIG. 3c).

The uneven pattern thus obtained differs in appearance and feel from that of Example 1, but this is because the pattern 4 of Example 1 does not include frits, but the pattern of Example 2 does not include frits. This is because 4' includes a frit. The resulting red uneven pattern did not have any particular points that could be distinguished from the use of crinkle enamel colored with paint, as in the case of Example 1.

Example 3 Colorless crinkle enamel with a relatively low melting point was gradually added to and mixed with a commercially available gold paste solution, and the mixture was dried by heating at about 200°C for about 10 minutes, so that the gold paste solution was coated in a dry state. I made crinkle enamel 8.

Next, in FIG. 4, a pattern 4'' of paste mixed with squeegee oil and frit is printed on the surface of glass product G by screen printing method (4th
After sprinkling and adhering the crinkle enamel 8 on it (Fig. 4b), approximately
By baking at 580° C., crinkle enamel 8 was fused together with gold and frit to the surface of glass product G, resulting in an uneven pattern 9 with metallic luster (FIG. 4c). The resulting uneven pattern with metallic luster exhibited an excellent decorative state not seen in conventional types.

In addition, in the present invention, in order to make the unevenness of the colored pattern rough, the ratio of flux mixed into the design oil for adhering crinkle enamel may be set low, or the number of meshes on the screen for screen printing may be set low. This can be achieved by increasing the printing thickness and making the printing thickness thinner. Also, if the unevenness of the colored pattern is to be smoothed, the above method may be reversed. Also, by mixing a different color pigment in the pattern oil for attaching the colored crinkle enamel and sprinkling the colored crinkle enamel on a part of the pattern, the colored part of the pattern is different from the part colored by the pigment. It is also possible to form a colored uneven pattern portion using crinkle enamel.

As described above, according to the present invention, crinkle enamel of any tone can be obtained by mixing pigments and coating the crinkle enamel with paint of a desired tone, and moreover, it is possible to obtain a colored uneven pattern using the crinkle enamel. In addition, since crinkle enamel of a desired color can be prepared each time it is needed, there is no need to prepare a large number of colors in advance, and there is an advantage that the area and labor required for storing colored crinkle enamel in stock can be saved. Yes, and its usefulness is extremely great.
