In this business era of pursuing quality of life, even a glass water bottle can be played with many tricks. As a result, many people are concerned about such questions as "can the glass water bottle be put in the microwave oven", "can the glass water bottle be heated?". This is because in our daily life, many people who use microwave oven want to directly heat the milk, boiling water, coffee and other items in the glass water bottle before drinking. However, there are also concerns that there will be varying degrees of trouble in heating the glass water bottle.
Can the glass water bottle be heated in the microwave oven?
Ordinary glass water bottle. Ordinary glass water bottle can not be used in oven or microwave oven. The heat resistance of ordinary glass water bottle is not better than that, and the temperature difference it can bear is only about 60 ℃. Either rapid heating or rapid cooling can cause the glass water bottle to burst. So don't put the ordinary glass water bottle into the microwave oven.
Toughened glass water bottle. Toughened glass water bottle without homogenization treatment, if used in oven or microwave oven, has the risk of self explosion injury. Tempered glass water bottle should not be put into the microwave oven for heating. On the one hand, it contains metal components and is fragile when heated. On the other hand, toxins will be released during heating, which is harmful to health.
Heat resistant glass water bottle. The heat-resistant glass water bottle can be heated in the microwave oven. Compared with ordinary glass water bottle and tempered glass water bottle, heat-resistant glass water bottle has smaller expansion coefficient and better high-temperature resistance. At the same time, it can withstand extremely cold and hot changes, so it can also be put into the oven. So if you want to heat milk and other drinks, you can pour it into a heat-resistant glass water bottle and then put it into the microwave oven.
Special glassware for microwave oven. At present, there are some special glassware that can be microwave oven, most of them are lunch boxes, and the bottom of them is marked with "microwave available". At the same time, the heat-resistant glass products are obtained by annealing and cooling, and their thermal stability is good.
Finally, it should be noted that the temperature difference that the glass can withstand is only about 60 degrees Celsius. For example, the room temperature is 20 ℃, so the water temperature should not exceed 80 ℃. If you want to install boiling water, you'd better preheat the glass water bottle with hot water. In addition, before putting the glass water bottle into the microwave oven, check whether the product is marked with the word "suitable for microwave oven". If not, it is not recommended to use it in the microwave oven.
