This round shaped kettle with a flat bottom is crafted of fireproof clay and has an inner heat-resistant covering. You may safely put it on a gas or electric burner as well as on a spirit stove. Boil the water slowly on a low fire until smoke comes out from the spout. The smooth glaze won’t give off a metallic taste that spoils the natural flavor of the tea and thick walls will keep the liquid hot for long. The kettle has a tight-fitting lid and a heat resistant bamboo handle that won't burn your hands. To maintain the temperature the vessel can be placed on a special teapot warmer with a candle inside.
