A customer suggested doing a black design on white and it is now one of my favorites.  Black glass is cut into small petal shapes and arranged in this classic repeating design on white glass.  The black glass is solid and the white glass glows around it.  This nightlight It is melted in a kiln up to 1445 degrees, fusing it together. I melt the glass at this temperature because it creates texture, so when you run your hand over this nightlight, you will feel each black piece rise off the white.
