Permanent (Stain) Colored Glass

The permanent color is the result of a high temperature, chemical bonding process, which puts the metal coloring agents directly into the molecular structure of the glass at its surface. The coloring ions penetrate into the glass approximately 10-50 microns deep. The color is the result of a complex relationship of time, temperature, chemicals and physical properties of the glass substrate. The finished product is a layer of color in the glass at the surface. The advantage of this color layer in the glass will not degrade when exposed to high heat, UV energy or abrasion. We are the only company in North America that uses this coloring process on a commercial scale.
