Black earthenware pot made of heat-resistant ceramic, compatible with far-infrared heating. - Material: Willceram (heat-resistant ceramic) - Type: Earthenware pot - Heating Method: Far-infrared (infrared heating) - Lid Type: Glass lid Size: Outer diameter (measured at the bottom) approx. 18cm Depth: 12cm I received this as a gift, but I already have a similar pot, so it has been stored at home for a long time. It is particularly suitable for roasting sweet potatoes and cooking black beans. The box is slightly deteriorated. Thank you for your understanding.
