This is a great 4-in-1 appliance that can cook, boil, steam, and bake! Please try it out! (Please try it once) Used a few times. - Features - ● Passed a 1000°C rapid cooling/heating test at a public testing facility, using "ultra-heat-resistant ceramic" that is resistant to cracking even when dry-heated! ● Can be used directly on a flame or in a microwave! ● Safe, as the amount of lead and cadmium leaching during heating is 0mg per 1L, which is impossible with metal pots! ● Good thermal efficiency and heat retention, saving cooking time and gas costs! ● The surface is treated to prevent sticking, making it ideal for simmered dishes like curry and stew! Seal part is deteriorated. See image. Material: Ultra-heat-resistant ceramic
