About Pyrophyllite

Pirofilite é um filossilicato de alumínio muito semelhante ao talco, formando massas lamelares ou fibrosas de cor branca a verde pálido com textura gordurosa ao toque. O nome deriva do grego para fogo e folha, pela sua esfoliação sob calor. Historicamente significativa como material de escultura na China, Coreia e algumas culturas africanas. A rocha agalmatolite, usada para esculpir pedras-sabão, contém frequentemente pirofilite. Os artistas chineses usavam-na para selos e esculturas. Embora raramente reconhecida como gema, amostras polidas com cor interessante têm apelo ornamental.
