Introduction: Zisha is a porous material with a double pore structure, fine pores and high density. Using a purple clay pot to brew tea does not lose its original flavor, and the fragrance does not disperse, and the true fragrance and taste of tea is obtained. Zisha pots have good air permeability, and it is not easy to change the taste of tea when brewed with it, and it will not go bad the longer it stays in the summer. The more the purple clay is used, the brighter the color of the pot body will be, and the more gentle and elegant the charm will be. The body of the purple clay pot will become more and more warm and shiny due to long-term use due to stroking and wiping.
