As we known, we need to drink at least 8 cups of water, so drinking water is very important for us at daily life. Everyone need to drink water to keep replenishing water and metabolism. And water cups, as the carrier for drinking water, also is very important existence for us. Now water cups at market normally are glass water cups with many different designs, so how to choose a high temperature resistance glass cups for avoiding broken is which we concerned about.
Actually here have a very easy method, if glass cups with high temperature resistance, once we put hot water at glass cups with high temperature resistance, it will not be hot. If glass cups without high temperature resistance, it will be hot. Some glass cups with double wall then can keep temperature and will not be harmful to hand.
High temperature resistance glass cups normally is made by high borosilicate glassware, they with a very low expansion of factor with this special material. Not only can bear 400°c high temperature but also can bear temperature difference 150°C around. If you only have normal soda lime glassware at your home, no need to discard, this normal soda lime glassware can bear 5°C-70°C liquid. The reason it will be broken is because of quenching heat to make glass cups with big temperature difference. So when you want to put hot water at glass cups, it’s better to put some warm water then add the hot one.
When you are purchasing high temperature resistance glassware, normally it will have marks at products to mention the using. Please must remember that can not purchase the cheaper one with high temperature resistance but actually not.
