This is because as long as the ceramic products, all need to be fired at high temperatures, ceramic mugs are naturally no exception, the main components of ceramic mugs are clay, porcelain clay, kaolin, coloring agents, lime glaze, etc.
The process of making ceramic mugs is very complex.
Need to practice clay, billet, printing adobe, billet, sun billet, engraving, glaze, kiln, color glaze, where the kiln is a very critical step, only after high-temperature firing, in order to extend the life of the ceramic mug.
This is also the advantage of ceramic mugs.
When buying ceramic mugs can be selected according to the following points.
