Hello everyone, I would appreciate assistance in identifying this item. I am new to the forum, I normally like to contribute before asking for help, but I'm afraid I don't have much to offer. This was an attic find. It is roughly 8"(20 cm) diameter (wide), 10"(25 cm) tall, with a 1 1/4" id 1 1/2" od(3.2/3.8 cm) opening. I can't get an accurate weight, but it is over 3 lb (~1.5 Kg), thick glass and heavy. There are no markings on the bottom, just a blob as seen in the images. Thank you all in advance.
