I have heated the lens to it's softening point, taking out the curve, so it functions as a platter. My firings are so subtle & precise, that all of the facets are still in tact.
This platter really sparkles in the light.
During the past few year, the local utility companies have been upgrading traffic lights, with new, energy efficient LED lights, that contain their own color. Lots of lenses went to the landfill, but many have been rescued by me & other similarly like-minded recycling artists.
Great for the Eco-minded,& the Car/Traffic Obsessed!
