This is a thick and heavy disk of clear glass with a dome shaped bottom. It is so cool looking and would make a great paper weight or shelf display piece to add interest. I suspect it may be a pillar candle holder with the flat side up. The domed side has a indented circle that could hold a votive candle or a tealight. It has the look of a Fire and Ice piece of glass. Very good preowned condition. 1 1/4" high x 5" in diameter. Weighs 1 lb 5 oz before packaging.
