This is a set of 4 handmade, colorful stoneware dessert plates with special effects. The paint used is food-safe. Stoneware is a clay-based material that is fired in the range of 1100-1300 degrees Celsius to produce plates and dishes. It is more durable than ceramic and is less absorbent. Due to being fired at a higher temperature, it can be safely used in the microwave, oven, and dishwasher for many years.
