Yi Xing (pronounced Yee-Shing) is a City in China known throughout the world for the deposits of rich clay in its surrounding landscape. Yi Xing clay absorbs and enhances the flavors of tea over time (just like a good cast iron frying pan!) Offered in a rich brown earth tone that is 100% natural - no dyes or glaze are added. For cleaning, use of strong soap is not recommended. Rinse with hot water and pat dry after each use.   Size:  12 ounces
