How is a ceramic mug made?

A ceramic mug is a cup made of ceramics and used for drinking wine, water, tea, etc. The so-called “ceramic” is a form of clay made of clay or other inorganic non-metallic materials, processed by molding, sintering and other processes to decorate and protect the walls and floors of buildings. After drying, it is heated to a certain degree to harden it and no longer dissolve in water.
