Introduction to the knowledge of clay practice in ceramics!

Craftsmanship: Refining the soul of porcelain clay with ingenuity

As the cornerstone of the quality of mid to high end ceramic tableware, Zhongqiang Porcelain Industry inherits the essence of ancient clay practice and combines modern intelligent technology to create high-density, defect free ultimate clay materials, laying an excellent foundation for subsequent shaping and firing.

1. Raw material selection: Carefully select high-quality natural kaolin, undergo mineral composition testing and impurity screening to ensure the purity and plasticity of the mud material.

2. Vacuum Mud Training: Using a fully automatic vacuum mud training machine, the mud material is subjected to strong kneading, pressing, and exhaust to eliminate internal bubbles and stress, thereby improving density and ductility.

3. Constant temperature aging: Mud materials naturally age in a constant temperature and humidity environment for more than 30 days, with fully fused molecules and uniform and delicate texture, avoiding the risk of cracking in the later stage.

4. Refining and shaping: Secondary refining and refining of clay particles, precise adjustment of softness and hardness according to the requirements of the device, achieving smoothness and stability in casting and injection molding.

Quality commitment of clay:

·The moisture content error of the mud material is ≤ 0.5%, and the density meets the first level standard of the national standard

·Each batch of mud material undergoes X-ray inspection to ensure no hidden defects

·Adapt to different glazes and firing processes, resulting in a 20% increase in finished product transparency and strength
