Due to an unexpected change in material availability, Speckled 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 #06242605 Speckled Turtle ^5-6 A warm brown speckled plastic clay good for all forming techniques. Offers nice warmth tones at cone 6 and gives a reduction look to glazes. Contains granular manganese. (Shr 11.5%, absorption cone 6 less than 0.5%) If you are interested in purchasing 300lbs + please email us directly for freight quotes Purchasing tips!
