Ultra-Heat Resistant Cookware The main features of this cookware are as follows: Excellent Thermal Shock Resistance: It has high heat resistance, so it won't break even if you put it on high heat (such as a gas stove) immediately after taking it out of the refrigerator, or if you put it in cold water immediately after heating. Versatile Heat Source Compatibility: It can be used not only on direct flames but also in microwave ovens and gas ovens. Efficient Cooking: Because it is fired at high temperatures, it has good thermal conductivity and boils quickly. Uses: Suitable for a wide variety of dishes, such as curry, gratin, and stew. We will pack it in bubble wrap and ship it in the original box.
