Pyrophyllite
Pyrophyllite is named from Greek pyr - fire, plus phyllon - a leaf, alluding to its exfoliation when strongly heated.
Pyrophyllite forms white, pale blue, yellow, green, brown, translucent or opaque, compact spherulitic aggregates of acicular radiating crystals or foliated laminae.
Pyrophyllite is used for ornamental carvings. The similarity to Soapstone increases ornamental interest in pyrophyllite.
