Is Soda-Lime Glass Toxic?

As for daily use of glass cups, soda-lime glass cups are relatively safe and reliable, and will not cause adverse effects on the body. Soda-lime glass is a silicate glass, which has relatively good chemical stability and relatively good thermal stability. For daily use, it has no toxic side effects, will not cause adverse effects on health, and its stability is relatively good.

Is Soda-Lime Glass Toxic?

There are many types of glass cups we come into contact with in our daily lives, and different glass cups have different effects. However, recently, the State Food and Drug Administration issued an urgent notice to stop the ordinary glass packaging. Defects in packaging will directly affect the use of glass, so many people are worried about whether the use of glass will be affected. Today, I will introduce you to some knowledge about drinking water at home. Let's learn whether sodium-lime glass is toxic!

What is Soda-Lime Glass

Before understanding soda-lime glass, let us first understand what soda-lime glass is. Soda-lime glass is mainly one of the silicate glasses, which is mainly composed of silicon dioxide, calcium oxide and sodium oxide. Such as commonly used flat glass, bottles, cans, light bulbs, etc. Sodium oxide increases the thermal expansion coefficient of glass and reduces the thermal stability, chemical stability and mechanical strength of glass, so the proportion cannot be introduced too much, generally not exceeding 18%. Sodium oxide is generally introduced as pure alkali during glass production.

The main function of calcium oxide in glass is to increase the chemical stability and mechanical strength of glass, but when the content is high, it can increase the crystallization tendency of glass and make the glass brittle. The calcium oxide content in general glass does not exceed 12.5%. It is usually introduced through raw materials such as calcite, limestone, chalk, precipitated calcium carbonate, etc.

So is the glass toxic? The answer is non-toxic, because its main ingredients are melts of silicon dioxide, calcium silicate and sodium silicate. Daily necessities made from it are relatively safe products on the market. When using glass cups, we need to pay attention to the fact that glass cups are relatively hard and brittle, their strength is not very high, and their thermal conductivity is relatively poor. Therefore, when using soda-lime glass cups, first pour in a little hot water, then rinse the bottle, and then pour in hot water.
