The Jianzhan teacup originated in the Jianyang District of Nanping City, Northern Fujian Province. Its popularity peaked sometime around the Song dynasty in China, then waned in the Ming dynasty. Fortunately, the tradition was carried on in Japan and Korea for many years after.
Although Jianzhan glazes are all basically the same, due to different firing temperatures and positioning within the kiln, each cup's fired glazing pattern becomes totally unique from any other.
These teacups are high in iron content. The insulative thickness helps retain the tea temperature without burning your hand.
