A fine-grain stone produced from the decomposition of feldspathic granite. Petuntze occurs in China, England and Wales. It primarily contains quartz, mica and fluorite. Also called China stone, petuntze was mixed with kaolin to make oriental porcelain. It is also used in glazes. Cornish stone is very similar (Mayer 1969).
