I'm a glass failure!

I've got a Barolac vase (flared top + roses, frosted) in the shed, and realised the base was different...but I was so sure this butterfly vase was class that I overlooked it.
I still can't quite get my head round the fact that this is probably a mass-produced piece of glass. It's so darned heavy and well made, and I haven't seen another like it. :cry:

I guess you live and learn, thanks for your help Mosquito. x
