Hand Made High Fired Pottery, by David Brown. Mr. Brown mainly uses a pale firing stoneware clay body. Occasionally, he uses a porcelain clay. His larger, hand (slab or coil) built pieces are made with clay, which he modified by the addition of sand, grog or grit and occasionally, he has impressed small shards of fired ceramic or glass into the surface. All my work is fired in an electric kiln, first biscuited to 1000C then to cone 8 about 1250C. See more of his pieces here.
