Vanessas 32 cm presentation plate is made from stoneware. Stoneware is a clay-based material used in the production of plates and dishes, which is fired and baked at 1100-1300 degrees. It is much more durable than ceramics and absorbs less water compared to ceramics. Being fired at higher temperatures, it can be safely used in the microwave, oven, and dishwasher for many years.
