Kaolin

About Kaolin ( Potassium and Magnesium )

Also called china clay, soft white clay that is an essential ingredient in the manufacture of porcelain and is widely used in the making of paper, rubber, paint, and many other products.

The main component of kaolin, as we call it, is the mineral kaolinite. Pure kaolinite is bright white, though kaolin clay often has other minerals present that add slight coloration to the clay, most often it has a pinkish hue from iron oxide or a greenish color from decomposing plant material.

All kaolin has the same basic properties, but the color variation actually indicated different benefits of kaolin clay.

When kaolin is mixed with water in the range of 20 to 35 percent, it becomes plastic.
