Powdered frit decorative porcelain

Abstract

The invention relates to a glaze famille-rose porcelain which adopts glaze pigment without lead and coloring oxide according to weight portion ratio of 9:1, and water color pigment and oil color pigment which are made by fine grinding the glaze pigment without lead and the coloring oxide in a mill is used for the porcelain glaze decoration, and the product is manufactured by firing under the temperature of 780 DEG C to 850 DEG C. The glaze famille-rose porcelain which replaces a lead flux of the traditional glaze coloring with the glaze and reduces all poisonous substances is characterized in that the glaze famille-rose porcelain is environment-friendly and safe in use and colorful in hue. The glaze famille-rose porcelain is suitable for various glaze decoration of transparent ancient color, grease paint, and mixed glaze, etc., on art porcelains, furnishing porcelains and domestic porcelains..

Description

technical field [0001] The invention belongs to the technical field of porcelain surface decoration, and relates to glaze pastel porcelain, which is suitable for various types of overglaze decorations such as transparent ancient paint, oil paint and pastel paint 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, excessive amoun...

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.
