Specialty Glass and Glass Ceramics

Corning Specialty glass has a broad range of capabilities including melting and forming as well as finishing and characterization. The versatile manufacturing capabilities enable production of more than 60 glass compositions each year in many different shapes including pressings, bars, strips, blocks, rods, sheets etc.


Different melting technologies enable production of glass :

  • From 1.4 to 1.9 index
  • From clear to tinted
  • From 2.5 to 5.2 density
  • With photochromic properties, from clear to dark or from tinted to tinted dark
  • With low viscosity
  • With sharp UV cut-off
  • With low Tg

A vast majority of glass types can be produced: White Crowns, Fixed Tints, Baryums, Flint, Soda lime, Boro Silicate, Alumina Silicate, lead glass, Lithia potash borosilicate glass, Lanthanum Niobium Borate glass, phosphate and Fluo-Phosphate glass, germanium based glass, glass ceramics…
