This is a hand blown vase, but in the style of early Pittsburgh pillar molded pieces. This does have some age as I can see the wear on the base. This is very heavy, thick, and solid glass. Like the ribbed stem ball. Measuring about 12" tall and 5 1/2" diameter. Ive had this some time, but do not know who made it. It has numbers etched into the pontil. A nice color too......sort of in between a teal and aqua. This is a uranium glass as the last photo shows it glowing under black light.
