It is said that if you use a Yixing tepot for many years, you can brew tea just by pouring water into the empty pot. Yixing (pronounced yeeshing) teapots date back to the Sung Dynasty (960-1279). This special purple clay contains iron, quartz and mica. It is superior to all other types of brewing vessels. Its porous nature absorbs the flavor of the tea and enhances its flavor each time. Recommended for premium high-grown tea.
