Activ-Low Fire Clay 

Activ-Low Fire Clay (formerly Blackjack Low Fire Clay) is a blend of several natural clays and minerals that produces a smooth white talc body with good plasticity. This earthenware clay is a light gray color when wet yet fires to white. It is great for hand modeling, hand building, slab rolling and can be thrown on a potter’s wheel. This clay is excellent for all skill levels from beginners to professionals, and is non-toxic certified.

This earthenware clay fires in a kiln to maturity at cone 06 and bisque fires at cone 04.

The clay will be shipped on a pallet in the form of filter cakes, for a total weight of around 2,480 lbs. Your order can be picked up at the plant in Marshall, TX or shipped.
