Lead glass, also known as lead crystal or flint glass, is usually used in optical work.

It is a type of glass that contains a high percentage of lead oxide (PbO) which gives the glass a higher refractive index and lower dispersion than normal soda-lime glass, which makes it useful for optical lenses and other optical components.

Lead glass has a higher refractive index which means that it bends light more than other types of glass, and a lower dispersion which means that it doesn't spread out different colors of light as much. This makes it ideal for use in lenses and other optical components where clarity and precision are important.

Lead glass is also used for creating beautiful glassware, because of its brilliant optical clarity, high refractive index, and high dispersion. It is also a good thermal insulator and has a high electrical resistance.
