Pottery, ice cream bowl, soup bowl, ceramic chili mug, stoneware cereal bowl. More Blue Parrot cups and mugs: http://www.etsy.com/shop/BlueParrotPots?section_id=6797001 Will hold up to approx. 26 ounces. Food, dishwasher, and microwave safe, as is all of my work. For tea, warm the cup with very hot tap water before filling with boiled water. Doing so will ensure better tasting era and extend the life of the cup.
