My fused glass artwork is coated with precious metals Gold, Silver, Titanium, Chromium, and Zirconium. A laser is shot at these precious metals to vaporize them. This vapor raises and condenses on the surface of the fused glass to create a crystal gemstone coating. The coating splits light into the color spectrum you see. It will change colors based on the distance and angles you stand from the piece. An Opulent effect is achieved.
