Soda Lime / AR / Flint Glass

Glass Type: Soda Lime

Description
Soda lime, also known as AR / Flint or Float glass, contains both sodium and calcium and is formed by drawing the glass over molten tin baths or redrawing into rod or tubing. Because of its chemical properties, soda lime can also be chemically strengthened to harden the surface and make it more scratch and break resistant. SGP can lap, polish, form, cut, and chemically strengthen this material to many shapes, sizes, and surface finishes.
