High borosilicate glass (also known as hard glass), takes advantage of the electrical conductivity of glass at high temperatures. It is created by passing an electric current through the glass at a high temperature.

Internal heating is used to melt the glass, which is then processed through advanced manufacturing techniques. Due to its coefficient of linear thermal expansion of (3.3±0.1)×10^-6/K, it is also known as 'Borosilicate Glass 3.3'. This type of glass has low expansion rates, high resistance to high temperatures, and is highly resistant to chemical corrosion.

High-intensity, high-hardness, high-transparency, and high-chemical-stability special glass materials, due to their excellent performance, are widely

Widely applied in industries such as solar energy, chemical, pharmaceutical packaging, light sources, and craft jewelry.
