I made this single coaster using a deep turquoise glass with green streaks running through it. That is complimented by clear turquoise glass and iridescent glass with a greenish hue. It is a stunning piece to look at, but equally practical as a coaster to place hot and cold drinks on it. I fused 4 pieces of glass together in my kiln, then placed bumper stops onto the bottom to stop it sliding. This would be a lovely gift if you can stand to give it away.

The coaster is 10 cm square.
It weighs 149 gm.
