Kaolinwasher Posted March 15, 2017 Author Report Share Posted March 15, 2017 i am also doing a porcelain test. with 30 custer and 20 flint in the 25 25 25 25 basic porcelain . For the flint I am using Sioux quartzite because it has some nice purple Iron in it . I want to see if it crazes, or shivers the glaze off.
