Problems solved by technology

[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

Description

technical field [0001] The invention belongs to the field of ceramics, and in particular relates to a method for preparing a green gold star chestnut tea kiln variable-glazed 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 ...
