The big ball of mud and kaolin porcelain which is good
Big balls are much better than kaolin. A big ball of mud is very rare only two places in the world, one is in Britain during the second world war has been mined over, one is in Chinese Hongjiang, the big ball of mud in the last century at the end of 70s has exhausted its scarce precious mining, known as the "gold mud".
The remnant of the large ball mud pegmatite is called kaolin. The ore has a big ball and a small ball. The big ball is 10-40 cm in diameter and the diameter of the ball is 3-4 cm. The size of a white mud ball, long hidden in the deep mountains and forests of Hunan Xiangxi, lived a secluded life underground". Thank you
