The Kelly Group, Inc. uses a variety of glass to create its Lighting products. Predominantly the following types of glass are used:

  • Borosilicate.
  • Soda-Lime.
The Kelly Group's capabilities include:
  • Sand Blasting.
  • Blowing.
  • Pressing.
  • Tempering.


Borosilicate glass:

     Offers excellent thermal properties. It is highly resistant to water, alkalis, acidic and saline solutions, as well as to chlorine, bromine, iodine and organic substances. Even over long periods of time and at high temperatures that exceed 100 degrees Celsius, borosilicate glass exceeds the chemical resistance of most metals and other materials.

Soda-Lime:

     Is a popular industrial glass made from large amounts of silica with smaller amounts of soda and lime. This glass is not particularly resistant to heat and is used in windows and bottles.

Sand blasting:

     Produces glass with a generally rough, non-transparent surface. The glass surface is blown with fine sand under high pressure.

Blowing:

     Is a technique by which molten glass is blown into various shapes and then cooled to a solid state. Products such as cylinders and drums result from the blowing process.

Pressing:

     Refers to the process used to form the inside shape of glassware. This process results in such products as the Fresnel lense. Since its invention in 1822, the Fresnel lense has been adapted for use in many lighting applications to increase the volume and quality of light without increasing heat or energy usage.

Tempering:

     Makes glass stronger and safer. Typically when an untempered piece of glass breaks it shatters into sharp shards that can be dangerous. When tempered glass breaks, which it does more reluctantly, it breaks into small cubes. Although still dangerous it is much less so than the sharp shards of untempered glass.
