Glass selection skills by material
Jul 06, 2022
More than 4000 years ago, glass was widely used.
With the progress of the new era and the rapid change of application technology, glass with various functions and unique materials appeared on the market.
The most common thing in daily life is a glass.
However, few people will consider the material of the glass when using it, whether it is safe and healthy, etc.
In fact, glass is just a general term. It still has many kinds of materials and common categories: crystal glass, high borosilicate glass, etc.
Glass is different from thermos cup. The quality of glass material directly affects the quality of glass.

Compared with other glasses, the basic materials and manufacturing process of high borosilicate glass are more expensive
But its safety factor is relatively high, even if it is suddenly cold and hot, it will not burst, and its high temperature resistance is particularly good.

Crystal glass is made of silicon and lead oxide. Its material is crystal clear and shiny, so it is named crystal glass.
Solid glass is also divided into lead-free crystal glass and leaded crystal glass
Lead free crystal glass has better refraction, slightly lighter than leaded crystal glass, and its sound is crisp and distant

Lead containing glass is recommended not to be used as far as possible, because its lead oxide content reaches 24%.
Long term use of items with large lead content will cause great harm to human nerves, hematopoietic system, kidneys and other organs.
Therefore, if conditions permit, you can give priority to practical high borosilicate and shiny and safe lead-free crystal glass, and never choose leaded glass.
