[0002] As an important material for arts and crafts, ceramics have a long history and rich cultural connotations. Although traditional ceramic handicrafts are excellent in aesthetics and artistry, they often lack in wear resistance. Ordinary ceramic materials are brittle and hard, and their surfaces are prone to scratches and abrasions, which not only affect the appearance of ceramic handicrafts but also reduce their service life and collection value.

The difficulty of the product lies in the balanced improvement of performance. At the same time, the light and weather resistance stability of the product is poor, which limits the use efficiency of the product. Summary of the Invention
