Purple clay: The purple clay (Zi Sha) has the characteristics of fast heat transmission and good heat preservation. Teapots made by this material are specifically designed to retain the aroma and flavors of the tea. It is better to use a certain Zi Sha Teapot only for one kind of tea.
This clay is porous when fired and is ideal for the making of teapots. Over time, the clay absorbs the flavors from the tea and releases them later. The teapots have become popular in China since the North Song Dynasty and were traded to many countries.
