Abstract

The invention relates to the technical field of new glass materials, and in particular discloses a method for manufacturing colored glaze for glazed porcelain. The manufacturing method of colored glaze for glaze carving porcelain is to melt and homogenize bright material, white material and color material in a kiln respectively; flow to the working part through the forehearth, and cool down to make it suitable for blowing; Secondary material blow molding process, the formed colored glaze has three layers from the inside to the outside, of which the first layer is the clear material layer, the second layer is the white material layer, and the third layer is the color material layer; the obtained colored glaze products Put it into an annealing kiln for annealing, and then cool with the furnace to obtain the product. The present invention can obtain a larger molar volume by adjusting the composition and relative content of the glass, thereby improving its crack resistance, and at the same time, the hardness of the surface glass will not be significantly increased, that is, the difficulty of glaze carving will not be increased.

Description

(1) Technical field [0001] The invention relates to the technical field of new glass materials, in particular to a method for manufacturing colored glaze for glazed porcelain. (2) Background technology [0002] China's porcelain carving art enjoys a high reputation in the world. The so-called porcelain carving is to use knives made of hard materials such as natural diamonds, artificial diamonds, and alloys to carve landscapes, flowers and birds, fish and insects, animals, and figures on the glaze of porcelain with knives instead of pens. It is an art that applies or does not apply color according to different glaze colors for works of various themes such as calligraphy, portrait and calligraphy. Porcelain engraving techniques include drill knife method, double hook method and scraper method, and porcelain engraving techniques are divided into spot engraving, line engraving, surface engraving and glaze engraving. In particular, the glaze carving technique is developed on the...
