This is a very heavy, blown, Murano Glass Ashtray, 6 1/2" in diameter. It is round with 1" thick surfaces. Aqua Blue exteriors, with Emerald Green interiors, and clear glass throughout. It has 12 notched, equally spaced, on the rim. May have been designed as an ashtray, all the rage in the 1950's, but never used as such. In fact, never used at all. The base is ground so the bowl does not wobble. There are a few scratches which may buff out.
