It can be used in the oven, on direct heat, and in the microwave. It's durable and can be used on direct heat, so it's an incredibly convenient pot for cooking things like stews on the stovetop, transferring them directly to the oven for cooking, serving them at the table, and storing leftovers in the refrigerator. It's old and has some stains. Size: Approximately 20cm square x 7.5cm high Materials: Glass (lid), Pyroceram (heat-resistant reinforced glass ceramic) Heat resistance: 500°C Manufacturer: Iwaki Glass (Corning, USA) What are the features of Pyroceram heat-resistant glass cookware? ■Features Because it is super heat-resistant, you can put food stored in the refrigerator directly on the heat. It is heat-resistant and allows microwaves to pass through well. It has good heat retention (cook over medium heat or lower, turn off the heat early, and you can still cook with residual heat). The smooth surface makes it easy to remove oil stains and odors. Maximum operating temperature: 1300°C / Normal operating temperature: 800°C / Heat resistance: 500°C
