How is it done?

The short answer is ..very well, but in reality, the patented GLASS Art process utilizes lasers more powerful than conventionally used in the engraving industry. Stone is melted into glass, and then color is injected into the stone. Finally, the image is chemically vitrified encasing it in a self-healing UV resistant layer of glass.

HOW LONG WILL IT LAST?

The four main enemies of outdoor imaging on granite are UV, oxygen, acid rain, and moisture. Each of these conditions have been countered with an appropriate strategy to minimize their detrimental impact..

Melting the stone to glass prevents moisture from causing failure from within the stone. Injecting the pigment into the stone creates a pit of pigment encircled by stone. The stone must erode away before the elemental pigment is removed. Encasing the image in glass seals it from O2, acids, and UV. The glass seal uses a self-healing formula, allowing the greatest longevity possible.

Finally, elemental pigment is applied roughly 4000-6000 times thicker than conventionally produced. The traditional method of color imaging on stone only lasts about 5 years outdoors. Our goal was to develop a method that would survive at least 100 years or more. Our test samples show no degradation, while samples produced later by conventional methods have already significantly deteriorated. The images are produced in such a way that they can always be restored, allowing an indefinite lifespan.

Traditional methods cannot achieve the bold color and detail that the patented GLASS Art process produces. The images do not disappear in the rain, and any granite type or color stone can be used. Lettering is sharp, clear and bold, and large or small size font is acceptable.
