Sorry if this is a repeat, Folks, but I'm a bit new to glass...I have a demijohn that I've carted around for years, and just recently decided to look into its history. I'll post a pic if I can figure out how, but the details are this: hand blown, no seams, aqua (I think it's called) glass. Pontial, tapered added lip, about 18 - 20 inches tall, lots of bubbles in the glass, really bulbous shape - it's gorgeous, in other words, and I'd love to know what I'm dealing with. Should I stick in the garage sale pile, or hang on to it? Thanks for any help you can offer with identifying it!
