This striking pink bowl is made with a special production glass called Sapphirine Striker. If held at 1225 degrees during firing, it develops a somewhat opalescent shadow. This piece was intentionally not held for that opalescent color development. This fused glass piece measures 10” across and 2 1/2” deep. While this bowl is food safe, please no microwave, dishwasher or oven. Sudden changes involving higher temperatures (oven, microwave, dishwasher) can cause thermal shock.
