After people's living standards have improved, various advanced electrical appliances have already appeared in our lives, such as microwave ovens, which are almost equipped in every household. Using a microwave to heat food is very convenient and simple, but there are also many requirements for using a microwave. Some consumers are curious whether glass cups and tea sets can be heated in the microwave.
Ordinary glass cups and tea sets cannot be used in ovens or microwaves. Uneven tempered glass, if used in ovens or microwaves, carries a risk of self explosion and injury. Tempered glass is not easy to heat in a microwave. On the one hand, it contains metal components that are fragile when heated, and on the other hand, toxins can precipitate during heating, which is harmful to health. At present, there are some specialized glassware on the market that can be heated by microwaves, most of which are lunch boxes. They often have a special label at the bottom that says "microwaves are available". At the same time, heat-resistant glass products are obtained through annealing and cooling, and their thermal stability is good. When consumers choose and purchase products that are labeled as heat-resistant glass but have a very low price, they should consider their authenticity.
Glass should be able to withstand changes between water temperature and ambient temperature of 60 ℃. For example, if the room temperature is 20 ℃, it is best not to pour more than 80 ℃ water. If you want to boil water, it is best to preheat it with hot water first.
In addition, before putting the glass cup tea set into the microwave, check if this type of product is labeled as "suitable for microwave". If not, it is recommended not to use it in the microwave, as safety is the first priority. Of course, in general, it is still safe to use.
Glass cup manufacturers will indicate whether the glass cup tea set has heat resistance based on the type of glass used and the production process. Glass itself is a very healthy material, so as long as the temperature is not too high, the glass cup tea set can be used well.
