Among all types of Zhuni clay, Zhuni Da Hong Pao is the highest grade, and it is rare for the bright and gorgeous red color. Zhuni Da Hong Pao has a very high shrinkage rate while firing, more than 30% at 1080ºC, which is trice more than Zini clay. For that reason, wrinkle, crack, collapse, and deform happen frequently in the kiln with low yield, so that it was only used for color decoration on normal Zhuni clay in ancient times, due to the lower skill that had in the past time.
 
This Gao Zhi pot is elegant for the vintage shape. The slick surface is very refined and has a lovely sandy texture, with the raw ore particles visible.

Suitable for all kinds of Oolong, Puerh, Heicha etc, especially ideal for the teas of large leaves, due to the roomy inner space.
