Next, scrape the upper end of the wet brick molded in the molding machine to a depth of 0.5 ~ 1mm with a wire brush.

Next, spread the dry oil on top of the body of the wet brick scraped with a wire brush.

Spread is made with vertical vibrating body. When the powder composition of the dry oil is put into the vertical vibrating body and the vertical vibrating body is operated, the dry oil powder composition falls in the vertical direction by the vertical vibration of the vertical vibrating body and is uniformly distributed in the horizontal direction on the upper end of the body.

Next, a method of displaying a pattern on the upper end of the wet brick by lubricating dry oil will be described.

One method is to spread the entire surface on top of the body with a vertical vibrating body based on one kind of color drying oil, and then put another type of color drying oil, for example, gold dry oil inside the vertical vibrating body. Unlike oil-based oils, when a vertical vibrating body is momentarily operated, gold dry oil gradually spreads evenly on the base oil, and a pattern like sprinkled with gold powder appears.

Alternatively, as in silk screen printing, a part of the gold mesh of the vertical vibrating body is masked with paper, a resin film, or a photosensitive material to match the pattern to be displayed, and then color dried oil. By simulating and repeating, we can express various colors and various patterns.

1A and 1B show that the gold mesh of the vertical vibrating body is masked.

The gold mesh of FIG. 1A is masked on the left side and the gold mesh of FIG. 1B is masked on the right side.

If you want to make a second degree color, apply the color dry oil of one color to the top of the wet brick with the gold mesh of FIG. 1A, and then the color dry oil of the other color with the gold mesh of FIG. 1b. In FIG. 1C, two colors appear.

2A, 2B and 2C show that the gold mesh of the vertical vibrating body is masked.

The gold mesh of FIG. 2A is masked on the left side, the gold mesh of FIG. 2B is masked on the center, and the gold mesh of FIG. 2C is masked on the right side.

When the third degree color is to be manifested, the color drying oil of one color is applied to the upper surface of the wet brick with the gold mesh of FIG. 2a, and the color drying oil of the other color is applied with the gold mesh of FIG. When the color dry oil of another color is applied, three colors are displayed on the upper surface of the wet brick as shown in FIG. 2D.

In this way, various patterns of various colors can also be displayed.

Next, the frit or cullet pulverized on the upper end of the base of the wet brick finished seeding is spread thinly in the front with a vertical vibrating body.

Next, the wet brick in which the upper end of the substrate is spread by frit or cullet is pressed by a roller heated at 80 ° to 90 ° C so as not to deform the substrate.

When pressed with a roller that is not heated, the substrate sticks to the roller and destroys the substrate.

If the second degree or third degree color is to be manifested, it may be pressed with a heated roller after every application of color dry oil.

Next, the body is dried for 1 to 3 days, and then calcined at a temperature of 1100 to 1150 ° C. for 30 to 40 hours in a reducing atmosphere in a calcination furnace to obtain a clay brick having a multicolored pattern.

Example 1 Patterned Clay Bricks Scattered with Gold Powder

The upper surface of the wet brick formed from the molding machine was scraped with a wire brush to a depth of 0.7 mm, and then mixed with 40 parts by weight of iron oxide of 20 mesh or less, 40 parts by weight of Hampyeong clay, 20 parts by weight of borax and 5 parts by weight of alumina. Uniformly spread gray-gray dry oil in a vertical vibrating body, and then, pink mica, 55 parts by weight of released clay, 25 parts by weight of manganese phosphate and 75 parts by weight of aluminum hydroxide were calcined at an temperature of 1160 ° C. in an oxidizing atmosphere. Instantly scatter a small amount of gold dry oil mixed with 10 parts by weight and 5 parts by weight of borax with a vertical vibrating body, and then spread the thin powder of frit thinly on the front with a vertical vibrating body, and then heat the upper end of the wet brick to 85 ° C. Press the press to a degree that the body is not deformed and then press it to dry for 2 days, and then fire it for 36 hours at a temperature of 1150 ° C. in a reducing atmosphere in a kiln. The gold powder turn got the clay brick pattern scattered on the grayish blue background.

Example 2 Clay Brick of 2nd Degree Color and Pattern

The upper surface of the wet brick formed from the molding machine was scraped with a wire brush to a depth of 0.7 mm, and then mixed with 40 parts by weight of iron oxide of 20 mesh or less, 40 parts by weight of Hampyeong clay, 20 parts by weight of borax and 5 parts by weight of alumina. The gray-blue dry oil is uniformly scattered only on the right side with a vertical vibrating body masked on the left side as shown in FIG. 1A, and there are 35 parts by weight of Chinese clay, 20 parts by weight of Jeongeup clay, 25 parts by weight of feldspar and 5 parts of borax on it. Yellow dry oil mixed with the parts is uniformly scattered on the left side with a vertical vibrating body masked on the right side as shown in FIG. Press the substrate to the extent that it is not deformed by using a heated roller and then press it to dry it for 2 days. Then, in the kiln, reduce the temperature to 1150 ℃ for 36 hours. To the left, the right, to obtain a grayish blue yellow this saliency clay.

Example 3 Clay Brick of 3 Degree Color and Pattern

The upper part of the wet brick formed by the molding machine was scraped with a wire brush to a depth of 0.7 mm, and then 35 parts by weight of Chinese clay, 20 parts by weight of Jeongeup clay, 25 parts by weight of feldspar and 5 parts by weight of borax on it. The mixed yellow dry oil is uniformly scattered on the left side by a vertical vibrating body masked on the right side as shown in FIG. 2A, and then 40 parts by weight of iron oxide having 20 mesh or less, 40 parts by weight of Hampyeong clay, 20 parts by weight of borax and 5 parts of alumina thereon. 2 parts of the gray-blue dry oil mixed with the parts are uniformly distributed only in the center with the vertical vibrating body masked on both sides as shown in FIG. 2B. Vertical vibration with a left side masked pink dry oil mixed with 20 parts by weight of pink pigment and 5 parts by weight of borax, calcined at an temperature of 1160 ° C. in an oxidizing atmosphere. Evenly spread on the right side of the furnace, and spread the fine powder of frit thinly on the front with a vertical vibrating body, and press the upper end of the wet brick so that the body is not deformed with a roller heated to 85 ℃. After drying, the resultant was calcined for 36 hours at a temperature of 1150 ° C. under a reducing atmosphere in a kiln to obtain clay bricks with yellow on the left, gray-blue on the center, and pink on the right.

Instead of applying wet oil to the dried body, dry oil was applied to the wet body to obtain clay bricks of various colors and patterns, and to prevent tissue destruction by applying the wet oil to the dried body. Yield could be increased, and even in tone, the surface became a matte mat, so that a clay brick having a rustic texture, which is the life of clay brick, could be obtained.
