Lampworking can be done with many types of glass, but the most common are soda-lime glass and lead glass, both called "soft glass", and borosilicate glass, often called "hard glass". Leaded glass tubing was commonly used in the manufacture of neon signs, and many US lampworkers used it in making blown work.
Borosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10 −6 K −1 at 20 °C), making them more resistant to thermal shock than any other common glass.

(Photo by Connor McHugh/PYROSCOPIC) Bob Snodgrass is an American lampworker known for his contributions to the art of glass pipe-making and glass art. He began lampworking in 1971 while learning from and working ...
Typical mercury-vapor lamps with an outer envelope made of soda lime or borosilicate glass still allow a relatively large amount of 365 nm UV radiation to escape the lamp. This can cause the accelerated aging of some plastics used in the construction of luminaires, leaving them significantly discolored after only a few years' service.
His rapid exhaustion of any given subject matter and his sudden interest in a new field have given him the reputation of impetuosity in the field of torch-worked glass art. His unusual precision at the torch, developed through the rigor of the master craftsman system of Germany, has earned him the nickname "Machine Hands." [citation needed ...
While blowing air is effective, blowing oxygen produces higher temperatures, and it is also practical to invert the roles of the gasses and blow fuel through air. Contemporary blowtorches and oxy-fuel welding and cutting torches can be considered to be modern developments of the blowpipe. Kit for blowpipe analysis Carl Osterland, Freiberg, c. 1870
Single-ended self-starting lamps are insulated with a mica disc and contained in a borosilicate glass gas discharge tube (arc tube) and a metal cap. [1] [2] They include the sodium-vapor lamp that is the gas-discharge lamp in street lighting. [3] [4] [1] [2]
Optical glass refers to a quality of glass suitable for the manufacture of optical systems such as optical lenses, prisms or mirrors.Unlike window glass or crystal, whose formula is adapted to the desired aesthetic effect, optical glass contains additives designed to modify certain optical or mechanical properties of the glass: refractive index, dispersion, transmittance, thermal expansion and ...
