Some small knowledge about ceramic tableware

1. Appearance quality standards

The current ceramic product standards are divided into three categories: superior products, first-class products, and qualified products. The appearance quality of high-quality products basically meets the requirements of "five no's and one small", that is, no spots, no falling slag, no colorless dirt, no pinholes, and no glaze scratches; First grade and qualified products have a greater tolerance for defects than superior products.

2. Thermal stability standards

The thermal stability standard refers to the absence of cracks or damage to a product during alternating hot and cold cycles. The quality of thermal stability can reflect the service life of ceramics, and the larger the temperature difference between hot and cold alternation, the longer its service life.
