Flecked Stoneware 1150-1290C - 2kg Clay Block

A 2kg pack of clay, perfect for testing before purchasing larger quantities Recommended Firing Range 1150-1290C / Cone 3 to 11 Indicative texture 4 (Smooth 1-Coarse 10). Shrinkage: 1100C = 9%; 1200C = 12% Attractively flecked stoneware body based on a ball clays and fireclay deposits mined from our site in South Staffordshire, near Walsall. Superb throwing properties for small or large pieces. Flecking burns nicely through covering glazes giving a reduction fired appearance under oxidising conditions. An extremely good body for thrown domestic stoneware. A note regarding fleck variation: The fleck size/density in our flecked bodies is variable from batch to batch due to the nature of the raw material supplied to us. The user must sample/batch test in their own application before proceeding. Potclays cannot accept any liability for fleck variations batch-to-batch which are outside of our control. Can I use items made from your flecked clays in the microwave? Yes - the fleck in our clays is created by an iron-bearing compound which is not metallic therefore will not reflect the microwaves. Tester size 2kg
