هل يمكن تسخين الكوب الزجاجي في الميكروويف؟?
في هذا العصر من السعي لجودة الحياة, even a small glass cup can be used in many ways. This has led to a heated debate: “Can glass cup be heated in a microwave?” Many people use microwaves to heat milk, water, قهوة, and other beverages directly before drinking, but they worry about the hassle of heating a glass cup. With this in mind, let’s discuss whether glass cup can be heated in a microwave.
- Soda-lime Glass cup
Soda-lime glass cup should not be used in ovens or microwaves. It has poor heat resistance and can only withstand temperature fluctuations of around 60°C. It is very susceptible to cracking when heated or cooled rapidly. Therefore, please note that soda-lime glass cup should not be heated in a microwave.
- Tempered Glass cup
Using unhomogenized tempered glass cup in ovens or microwaves increases the risk of spontaneous explosion and injury. Tempered glass cup should not be heated in microwaves. Firstly, because it contains metal, it is easily brittle when heated. Secondly, heating can precipitate toxins, which can be harmful to health.
Heat-resistant glass cup can be heated in a microwave. Compared to regular glass cup and tempered glass cup, heat-resistant glass cup has a lower coefficient of expansion. It also offers excellent high-temperature resistance. Furthermore, it can withstand extreme heat and cold, making it oven-safe. So, if you want to heat a beverage like milk, pour it into a heat-resistant glass cup and microwave it.
- Microwaveable Glassware
Currently, some specialized glassware that can be heated in microwaves has appeared on the market, most of which are lunch boxes. These items typically have a “microwave safe” logo on the bottom. Heat-resistant glass products, which are annealed and cooled, have excellent thermal stability. When purchasing products, consumers should be aware of the authenticity of inexpensive products labeled as heat-resistant glass.
Here are some tips for you:
Glass can withstand temperature fluctuations of at least 60°C. على سبيل المثال, if the room temperature is 20°C, keep the water in the glass below 80°C. If boiling water is needed, preheat it. Also, before placing glass in the microwave, check if the product is labeled “Microwave Safe.” If not, avoid microwave use. Safety comes first.
