Novel color china

Abstract

The new type of famille-rose porcelain has glaze surface decorated with water color pigment and oil color pigment, which is prepared with no-lead glaze pigment and coloring oxide in weight ratio of 9 and through fine grinding in mill, and is baked at 780-850 deg.c. The present invention replaces glaze for traditional lead flux of overglaze color, resulting in no toxic matter, safe use and rich colors. The present invention is suitable for overglaze decoration of various kinds of artistic porcelain, furnishing porcelain and daily use porcelain.

Description

technical field [0001] The invention belongs to the technical field of porcelain surface decoration, and relates to a new famille rose porcelain, which is suitable for various types of overglaze decorations such as transparent ancient paint, oil paint, pastel paint, etc. on artistic porcelain, display porcelain and daily-use porcelain. Background technique [0002] Pastel porcelain, also known as soft-color porcelain, was created in the late Kangxi period of the Qing Dynasty. It is a kind of glaze color and is one of the four famous porcelains in China. The traditional craft is to draw a pattern on the glaze of white porcelain first, then fill in a layer of "glass white" (a painting material containing lead, silicon, and arsenic, which mainly acts as a flux), and then paint with color material. It is baked in a color oven. Because the overglaze decorative color material of traditional famille rose porcelain uses lead-containing compounds as fluxes, excessi...

AI Technical Summary

Problems solved by technology

In order to reduce the dissolution of lead and cadmium, people try to use underglaze color and glaze color to replace overglaze pastel, but because the firing temperature is as high as 1300 ℃ and 1200 ℃ respectively, the range of pigment selection is small, and the range of hue is too narrow. It is inferior to overglaze colors in terms of hue and type, and has problems in terms of manufacturability and cost, making it difficult to be accepted by the market. Therefore, overglaze colors with relatively low firing temperatures are still the main decoration method for daily-use porcelain.
