Kaolin is better known as white china clay. The clay is used to create porcelain as well as a drug that treats diarrhea. Kaolin is used to mix with paper fibers to produce glossy paper used for magazines. Kaolin is an ingredient in paint and rubber.
Georgia is a major producer of kaolin. When I was a kid, we would go to what we called the chalk mine to get chalk to draw on the asphalt road. The chalk mine was where kaolin was naturally found on the surface. Below is a picture of a kaolin deposit.
