Product Description

Product Description 

Lead glass is primarily composed of silica and lead. It has moderate electrical resistance, density, refractive index and x-ray absorption rate.

     The softening point of lead glass also tends to lower than that of soda glass. It exhibits moderate durability and is easily worked.

    Major uses are stem and exhaust tube of fluorescent and incandescent lamp. It is also used for neon signs, pilot lamp, starter lamps and electron gun for TV braun.
