Problems solved by technology

[0004] The traditional Venus glaze is only suitable for flat ceramic products due to its good fluidity, not suitable for vertical ceramic containers such as cylinders, which is prone to sticking defects, and is only suitable for slow firing, high firing temperature and long firing cycle , need more than ten hours, such as rapid sintering, there will be defects such as small crystals and small quantities, which are only suitable for small batch production, and the production cost is relatively high

Abstract

The invention relates to a preparation method of a fast-fired colorful starry-sky bright glaze ceramic container. The preparation method comprises the following steps: (1) preparation of a blank; (2) biscuiting; (3) preparation of a glaze; (4) glazing; (5) glaze firing; and (6) inspecting. According to the invention, a glaze surface is good in quality, unique in color and texture, short in a firing period and integrally environment-friendly and safe.

Description

technical field [0001] The invention belongs to the field of ceramics, and in particular relates to a method for preparing a colorful starry sky bright glaze ceramic container. Background technique [0002] Ceramic products are calcined at a temperature above 500 ° C from the embryo body made of traditional mud formula, which has many shortcomings. The ceramic products made have low density, high water absorption, and are prone to leakage, deformation, glazed surface, and Defects such as pinholes, thin glaze, and shrinkage glaze, and most of the properties of the current billet are not suitable for mechanized assembly line production, resulting in low quality and high production costs. [0003] In recent years, with the changes in the market environment, it is very difficult for domestic ceramic enterprises to survive and develop under the environment of rising production costs and vigorously advocating a low-carbon economy in today's society. Increasingly demanding. In ad...
