Due to an unexpected change in material availability, Big Turtle has undergone a temporary reformulation. We feel confident in its fired performance, glaze response, and workability. However, you may notice a slight shift in feel and color, particularly in its moist form. We recommend that you test it before putting into production. This affects all batches dated after #06012601 A nice toothy, plastic stoneware body that fires a reddish brown at cone 6. Throws and hand builds well. Matures cone 5-7. Won't warp or bloat at cone 7 if slow fired through last 300F. Gives nice warmth to glazes, giving that "reduction look" in oxidation. Fine grog for tooth. Gorgeous in soda and wood firings too up to cone 8. Shrinkage 11.5% Abs at cone 6 less than 0.5% If you are interested in purchasing 300lbs + please email us directly for freight quotes Purchasing tips!
