Kaolin During the weathering of intrusive rocks a process known as "kaolinization" occurs wherein the sodium feldspar breaks down into kaolin group minerals – kaolinite and halloysite. Both are hydrated aluminosilicate minerals. Kaolinite (Al 2 Si 2 O 5 (OH) 4 ) occurs as plate-like sheets that commonly appear as "stacked books".

The mineral kaolinite primarily makes up kaolin. Depending on its source, kaolin also contains various other minerals, including muscovite, quartz, feldspar and anatase. When kaolin comes out of the earth, it's naturally bright white, but may have a yellow or rust-colored stain due to its exposure to iron oxide.
