Notes

(Richard Willis)

A clay-making mineral of a sub-group (including its rarer forms, dickite and nacrite, halloysite, and allophane, which are chemically similar to kaolinite but amorphous) within the group kaolin-serpentine (halloysite, lizardite, chrysolite), of the ideal form 2SiO₂ Al₂O₃ 2H₂0 (or, Al₄[(OH)₈, Si₄O₁₀]) with a typical empirical analysis of Al₂O₃ 39.5%; SiO₂ 46.5%; H₂O 14%
Hardness: 1 Density: 2.6 Soluble in H₂SO₄ Principal mineral of kaolin clay.
