How much do you know about the functional classification of glassware?

[Ordinary Glassware]

The chemical composition of common glassware is mainly based on sodium-lime silicate glass system. Soda lime glass is easy to melt processing, low price, so there is no special requirements for heat resistance and chemical stability, so it is widely used in ordinary glassware products.

[Crystal Glassware]

Crystal GLASS IS a kind of high-grade art glass, smooth and transparent, just like natural crystal, so it is also called crystal glass. Crystal glass can be divided into 3 kinds by lead content, such as low lead crystal glass, middle lead crystal glass, high lead crystal glass. According to the lead or not can be divided into lead-free crystal glass and lead crystal glass two categories.

[Heat resistant Glassware]

The so-called Pyrex glass, it is required that the glass has a certain thermal stability. For glassware, the heat and cold resistance of glass should be satisfied first. The chemical composition of such glassware generally depends on the choice of borate glass system.

[Microcrystalline Glassware]

The so-called glass ceramics, is in the specific base glass to add a certain nucleating agent composition, according to the conventional method of melting, formation, and then heat treatment at a certain temperature, glass into microcrystals and glass. Uniformly distributed composite materials are called glass ceramics, also known as glass ceramics or crystalline glass.

[Tempered Glassware]

Toughened glassware is a kind of product which is made of ordinary glass and processed by toughening to improve the mechanical strength of glass. Tempered glassware can be divided into air-cooled tempered and liquid-cooled tempered according to the different tempering processes. And chemically toughened glassware.
