Ball clay is not a clay mineral in itself, but contains other minerals, primarily kaolinite (but also montmorillonite, halloysite, and illite). Mica and quartz are also present in substantial amounts (e.g. 10-20% for Tennessee ball clays). Ball clays are very plastic and much finer-grained than kaolins.Web

One is using air-dry clay, which I have shown you. The other method uses red potter's clay powder and the process of making seed balls is a little different. You can visit my personal garden blog to see how to make seed balls using this alternative method and a very cool way to package them using toilet paper rolls here.Web

Josh, I am very interested to hear how you make out with your ball mill. I also have been planning to make one. I dig my own clay and have been using the slaking method. It does work, but, during a residency i did recently, I had access to a ball mill. I found you just cant beat it for making dry material for glazes and slips.Web

Ball Clay - Mined ball clay, which typically has a moisture content of approximately 28 percent, first is stored in drying sheds until the moisture content decreases to 20 to 24 percent. The clay then is shredded in a disintegrator into small pieces 1.3 to 2.5 centimeters (cm) (0.5 to 1 in.) in thickness.Web

First, its particles are typically very small. Second, it absorbs water. A 10% or greater addition of kaolin or ball clay is typical in many glazes. That amount suspends most glaze ingredients.
