What is lead glass
Lead glass is made into lead glass by adding lead oxide on the basis of ordinary glass. The raw material produced by lead glass factory is a large piece of glass. After processing, it can be made into lead glass of different sizes and shapes.
Lead glass generally refers to flint glass. A glass [GLASS] first made in England in the 7th century by George Ravenscroft, who used English flint as a source of silica (the basic ingredient of glass). The name was later used to refer to LEAD GLASS in England, although the source of silica for lead glass was not flint, but sand.
Optical glass with large lead oxide content, high refractive index and considerable dispersion value. According to the increase of lead oxide content, it can be divided into three types: light, heavy and extra heavy. It is used to make lenses, prisms, mirrors, etc. in optical instruments such as microscopes, telescopes, cameras and sights. In combination with crown glass, lens aberrations and chromatic aberrations are eliminated.
