Pyrophyllite - Wikipedia
The compact variety of pyrophyllite is used for slate pencils and tailors chalk (French chalk), and is carved by the Chinese into small images and ornaments of various kinds. Other soft compact minerals (steatite and pinite) used for these Chinese carvings are included with pyrophyllite under the terms agalmatolite and pagodite. Pyrophyllite is easily machineable and has excellent thermal stability, so it is added to clay to reduce th…
