Shower tiles

These tiles glow in the dark after being exposed to light. I began by making a clay prototype of the 4x8 inch tile, making a mold of it, and taking the glass to a temp where it flowed. It is great to see in the dark, the multi colored large tiles and the blue squares ones glow. I would have had the cleanest children who never needed to be asked to take a bath if I had made these when they were little. =)
