First of all, the glass used to hold water, of course, is transparent without impurities, can not have cracks, bubbles and other bad phenomena, such a glass is the best. Secondly, the cup must be strong, can not have scratches, damage and other situations. If it is the glass that holds the drink, it also has a lid, which can prevent the flavor of the drink from flowing into the cup. Moreover, it is best that there is no odor in the glass. The main reason why glasses can not have odor is that glasses are made of glass materials with high lead content in the production process. We also know that lead is very toxic, and it is very harmful to human body to drink water from glasses with lead content for a long time. If you pour hot water into the glass or pour boiling water directly into it, small pores will appear on the glass wall to help dissipate heat, which can easily lead to the release of harmful substances in the food. Therefore, for the health of you and your family, we'd better not pour hot water into it. Finally, one more thing to note: never microwave a glass! Many people put ice in the glass or put the glass in the microwave. This is because glass is not directly heated material, if hot water is poured into it, it will lead to many small cracks or bubbles on the surface of the cup. Therefore, if you want to drink water from a glass or heat coffee or tea, be careful not to pour boiling water directly into it. Although glass products are more common in life and easy to use, low cost and other advantages make it more common in life, but we must pay attention to its quality and safety problems when choosing.
