Problems solved by technology

In this method, the treatment agent on the surface of the pottery needs to be treated without glaze first, and then fired. Due to the low firing temperature and long firing time, not only the coloring effect is not stable enough, but also affects the quality of the pottery itself, and the process is long. ,low efficiency

Abstract

The invention discloses a process for making chromatic color on crockery and pottery surface with no glaze luster, including the steps of, high temperature burning hand finishing greenware, polishing the blank surface, first roasting the greenware coated by coloring agent, applying multicolor pattern onto the greenware, second forming by baking, spraying a layer of heatproof coloring agent onto the greenware, after baking, coating the impression-transfer glue brush onto the transfer paper and plastering it onto the greenware with coloring agent, placing it into the hot transfer press baking oven for baking, tearing the transfer paper for formation.

Description

Technical field: [0001] The invention relates to a pottery surface treatment process, in particular to a treatment process with unglazed luster on the pottery surface. Background technique: [0002] At present, there are many techniques for coloring the surface of pottery, but generally all adopt the method of secondary firing, which makes the combination of color and pottery surface unsatisfactory and easy to decolorize. A Chinese patent discloses an invention entitled "Surface Treatment Method for Advanced Ceramic Technology", and its patent application number is: 99108073.4. The method described in this patent application technology includes: pottery blanks entering the factory, washing and polishing, grilling, applying surface treatment agents, first firing, pattern decoration, second firing, quality inspection, and delivery. In this method, the treatment agent on the surface of the pottery needs to be treated without glaze first, and then fired. Due to the low firing t...
