This very fine clay is used in the making of the popular Yixing Tea Pots and for high quality bonsai pots that meet the needs of the bonsai professionals in Japan and around the world. The use of this clay for bonsai pots was popularized by Hirata Atsumi of the Begei Kiln in the Tokoname region of Japan Yixing is the pottery capital of China. According to historical evidence the ceramic production in this area can be traced back 7,000 to 8,000 years. The purple sand (zisha) clay for which this area is famous is mined in the Yellow Dragon Mountains at Dingshu Town. Contrary to its name this clay comes in a brownish purple, a yellow and a red clay. This is the same area in which many of the antique Chinese pots so revered in Japan were produced.
