I made this coaster with pieces of pretty blue and green glass, with a green-tinged piece of iridescent glass in the middle. The iridescence is hard to show in the photos, but when viewed at the right angle, it has a golden-greenish sheen. I fused 4 pieces of glass together to make this coaster, which is lovely to look at or practical to place hot and cold drinks on.
The coaster is 10cm by 10 cm square.
It weighs 152 gm.
