Good heat resistance, beautiful, easy to make materials, clean, easy to wash, not easy to corrode. The other side is production: ceramics are made of clay, and the physical properties of clay before becoming ceramics are: plasticity (paradigm) is large, easy to make. Therefore, most of the bowls and plates we use in daily life are made of ceramics. First, the clay paradigm (plasticity) before production is large, and after firing into ceramics, it has high wear resistance, hardness, high fracture toughness, and high melting point, making it practical.
