Put this hand-thrown bowl safely in the microwave or diswasher. Made by Normandy Park potter Don Schindler. The bowl is 10" in diameter, 2" high, white inside with wax resist decoration in the center, dark blue outside, wheel-thrown porcelain clay, lead-free glazes, dishwasher and oven safe. However, do not put in oven right out of the refrigerator. The artist suggests also that you not put this casserole in a hot oven - let it warm up with the oven.
