Purple Sand Tea Mug is calles as “ Zisha “ in Chinese . This is a special kind of clay that is used to make Tea Pots/ Mugs in China for over a thousand years. The history dates back to the early Song Dynasty. The purple sand mug is said to absorb a tiny amount of tea and flavour while brewing the Tea. Hence it preserves the flavour and taste of the Tea.
