For added strength and durability it is high-fired to 2400°. On the bottom is Tama's inscribed signature and date. Like everything at Prairie Fire Pottery it is handmade, lead-free, microwaveable, and food & dishwasher-safe. All the pieces in this offering are from the same kiln firing and have been carefully matched in size, shape, color, and glaze pattern. However small variations do naturally occur.
