This handmade one-of-a-kind Trinket / ring / votive dish measures 3 ½" square by ½" deep. It isa pale grey powdered bamboo on an iridescent base glass. I cut two pieces of glass for this, so it measures 6 mm thick. It was fired in a kiln to 1460o. It was then returned to the kiln a second time and fired in a mold to get its shape. This little dish is great for keeping your rings in, I have one by every sink. Can also be used for a votive, paper clips, bobby pins...any small objects. Not recommended for the dishwasher. Hand signed on the bottom.
