What is the heat resistance temperature of glassware made of borosilicate glass for microwave ovens and electric ovens?

 　Generally speaking, the heat-resistant temperature of microwave oven and electric oven glassware made of borosilicate glass is higher, usually able to withstand high temperatures of about 400℃ - 500℃.

 It should be noted that different manufacturers of borosilicate glassware, due to differences in formulation and production processes, the specific heat-resistant temperature may vary. Some of the better quality borosilicate glassware, the upper limit of its heat-resistant temperature can reach 500 ℃ or even higher; while some products may be about 400 ℃ to reach its limit of resistance. In use, be sure to carefully check the product instructions identified in the heat-resistant temperature range to ensure safe use. In addition, although borosilicate glass thermal stability is good, but also to avoid instantaneous changes in the temperature difference, such as just removed from the high-temperature environment of the utensils do not immediately contact with cold water and so on.
