Are there any toxic side effects of glassware?

The main component of glass is silica, but there are other components thought to add and change the properties of glass, such as lead, chromium and uranium. This kind of glass is not suitable for storing food, etc. Although these highly toxic elements exist in a chemical state, they will inevitably cause harm to the human body. Fortunately, glass containing these elements is colored and easy to distinguish.

Also: Glass is directly used in the production of mineral raw materials, such as limestone, quartz sand (99% content of silica, an important part of glass), soda ash (sodium carbonate), etc., because it is a natural mineral, it will inevitably bring in some impurity elements, so when buying glass products, especially when holding food containers, pay attention to choosing crystal clear and regular products. Do not choose a color consultant! Cutlery is also recommended not to choose plates with patterns printed on the glass.

Because those patterns are easy to crack under high temperature conditions, producing toxic substances. Of course, manufacturers can still buy with confidence, and they cannot be killed with one stick. Plexiglass can hold food, but not overheating, which can poison or damage the container.
