Coasters are created from salvaged glass shelving and vitreous enamels. After applying the enamels, they are fired in a kiln, bonding the enamel to the glass and polishing the edges.
Coasters would be perfect for drinks, to hold a smaller candle or even as a spoon rest. I strongly recommend that you hand-wash. There are clear silicone feet on the bottom, I did not use a permanent glue to attach them in case you would like to mount them to display as art (or in a back splash, etc.) If you would like to make the feet more permanent, I suggest peeling them off and putting a dab of e6000 or silicone caulk on them and reapplying.
Hand-cut tiles, range from 3 1/2" - 4" square - all are big enough to hold a can.
