A high-quality glaze must withstand scrubbing with cleaning tools and detergents, and sometimes contact various components in sewage. Therefore, the glaze must be non-absorbent, impermeable, and possess a certain thickness, smoothness, and lubricity, as well as adequate hardness and excellent wear resistance. Additionally, it should be crack-free and non-peeling.
Consequently, the glazing process involves numerous critical control points, with key ones listed below:
- Scientific Ingredient Ratio
The main raw materials of glaze include feldspar, kaolin, talc, quartz, etc. Tangshan, a major kaolin producing area, boasts abundant resource advantages, a long-standing ceramic industry history, a strong talent pool, and leading R&D capabilities across various fields. Rich experience has been accumulated in the R&D of glaze formulations.
- Strict Quality Management System
Weekly analysis meetings are held with technical personnel from laboratories, firing, and glazing departments to review the physical properties of glaze slurry and the quality of glazed finished products.
Weekly quality analysis meetings for green bodies and white bodies are conducted with technical personnel from molding, glazing, and firing departments.
Glazing quality control charts are compiled and posted by each work team.
All glazing processes adhere to international quality standards, ensuring the durability and reliability of ceramic sanitary ware.
