Technology for embedding metal into blue and white porcelain

Abstract

The invention discloses a technology for embedding metal into blue and white porcelain. The technology comprises the following steps: (1) sketching blue and white patterns and metal patterns on a manufactured porcelain body, digging ink mark slots along the ink marks of the metal patterns, then putting the porcelain body into a kiln and firing for the first time; (2) coloring the blue and white patterns, then putting the porcelain body into the kiln and firing for the second time; (3) enabling the bottom surfaces and the walls of the ink mark slots to be evenly coated with white vaseline, enabling the metal to be melted, pouring the melted metal into the ink mark slots, enabling the melted metal to be solidified, grinding and leveling; and (4) spraying clear glaze onto the porcelain body, then putting the porcelain body into the kiln and firing for the third time. According to the technology, the porcelain body is fired for three times, so that the blue and white patterns can fully present colors, and better metallic luster is realized; the metal and the porcelain are combined into a whole, so that the product not only has the freshness and beauty of the blue and white porcelain, but also is endowed with the grave and deep feeling of the metal; and therefore, the artistic value and the commercial value of the product are greatly improved.

Description

technical field [0001] The invention relates to a manufacturing process of ceramics, in particular to a process of inlaying metal in blue and white porcelain. Background technique [0002] Blue and white porcelain refers to the underglaze color that draws the outline of the blue and white pattern on the surface of the porcelain body, then uses the blue and white cobalt material as a colorant, and then applies a transparent glaze. Blue and white porcelain is famous for its freshness and beauty, innocence, crispness, tranquility and elegance, and is deeply loved by people. The process of inlaying tin, gold, silver, copper and other precious metal materials on porcelain is generally to draw the line outline of the metal pattern on the porcelain body, and dig out the ink groove along the line outline, then put it in the kiln for bisque firing, and then Molten metal is poured into the ink tank to solidify into shape. Porcelain inlaid with metal presents a solemn and vigorous ch...

Problems solved by technology

At present, the combination of blue and white porcelain and metal inlaid on porcelain has not yet appeared in the market, and the integration of these two processes has the following technical difficulties: First, due to the different expansion coefficients of blue and white porcelain and metal, when firing During the production process, either over-firing will cause bubbles, discoloration, and cracking of the blue and white pattern, or under-firing will cause the metal pattern to have poor luster and gray patterns; second, there is a lack of affinity between the metal and the porcelain body, and the metal pattern and the porcelain body There are gaps between them, and they will fall off after a long time
