Hand-built from Grolleg porcelain. Each bowl is uniquely textured. Available colors are blue celadon, amber, creme or charcoal. The form is based on the Japanese winter tea bowl, and is useful for tea, ice cream, soup or as a serving bowl. Food, dishwasher and microwave safe. Do not place directly from fridge to microwave or oven or vice versa as it will shock the porcelain and may create stress cracks.
