How to choose a glass? Here comes the lightning protection guide
Glass with color/pattern
Most of them are sprayed/decaled, and are used to hold hot water or acidic drinks for a long time, which has heavy metal hazards.
If you want to buy a safe glass, choose a transparent water cup without a pattern, and the carafe and glass bowl are the same.
When buying glasses, look at the material clearly
Soda-lime glass: It is thicker and heavier, but it is only suitable for cold water, and it may explode when exposed to hot water.
Crystal glass: lead-containing low temperature resistance is easy to cause poisoning, and lead-free low temperature resistance is poor.
High borosilicate glass: strong hardness, high temperature resistance, cold and hot will not burst and relatively safe.
If you're looking for a good glass, get started.
