Beginning Directions (you need a demo from Louis first)

Do not roll clay barrels outside. Wear a dust mask when using powdered ingredients and stay out of the dust. Mix Clay with the back doors closed. Clay that is mixed wet and then dried out works better (more plastic) than clay that starts with too little water. Do not mix clay with long skirts, aprons or dangling or loose jewelry or clothing.

  2. Add 2 scoops of FireClay, One Scoop Ball
