Handcrafted Wax Burners are made from Stoneware clay. They are glazed and fired at a high temperature of 1200C. I would recommend you place a coaster under the wax burner to keep your furniture from heating up. Please note, the wax burner dish will form a burnt mark from the candle underneath - this is perfectly normal.
Please note, as these are handmade, they are all individually unique and will vary in size and glaze application. Due to the boobs in the wax dish, it can be difficult to remove the excess. Try a toothbrush to get under the boobs and then pop in the dishwasher or hot water.
