The glass mosaic tile Delphinus is a glow in the dark glass mosaic tile.
The Fosfo Collection is even better with the lights off. These tiles are treated with a specially designed colorant that gives off a phosphorescent light.
They charge up from the sun during the day and emit light during the night.
Delphinus has a combination of:
Blue Iris (4%)
Azur (42%)
Ocean (40%)
Zafiro (14%)
