The collection is made with heavy stoneware and topped with a beautiful heavy application of reactive glaze making each piece substantial and very well made. The reactive glaze makes for a stunning array of colors likely found on hand-painted one of a kind ceramics. Each piece is slightly unique due to the reactive glaze giving you a handcrafted feel. These pieces are all dishwasher safe, oven safe up to 300f degrees, and microwave safe (they will get warm). Each platter can be used for serving both hot or cold dishes. Feel free to pre ahead and keep cool in the refrigerator or warm in the oven going from the kitchen to the table in style.
