This is a HARIO earthenware pot. A whistle is attached to the top of the lid to let you know when the rice is done. When the whistle sounds, turn off the heat and let it steam for about 15 minutes. The rice continues to cook slowly during the steaming process, using the heat stored in the pot to bring out its deliciousness. The key feature is the glass lid. You can check the contents of the pot without opening the lid while the rice is cooking. - Type: Earthenware pot - Material: Ceramic and glass - Color: Black - Lid shape: Dome Size: For 2-3 go (rice measure): Width 270mm, Depth 230mm, Height 210mm, Diameter 200mm I've used it for about a year.
