In the raw materials website section, I've separated "Dry Clay" from "Chemicals." If you're going to order less than a full bag of an item, look in the "Chemicals" section. Items that are typically purchased in large quantities (like Ball Clays, Kaolins, Feldspars, etc) for mixing clay, those are found in "Dry Clay." Although something like soda ash might be purchased in a 50# bag, but it's rarely purchased in anything much larger, so you'll find that in "Chemicals."
