Hi Cat,
My vase has exactly the same finish to the rim: smoothed but not actually ground very smooth. It's the same height as yours : 15.5 cms or a tad over 6 inches. The base is also the same as yours. I imagine the two vases will weigh the same as well.
I think we are looking at decent quality, individually made vases, but made in some bulk. I was intending to sell mine, but I've grown rather fond of it now even though it's completely the wrong colour and not at all my usual taste!
Before the thread got lost in the ether, I think someone suggested they are of Czech origin, using old moulds from some 50 or so years ago, and I rather suspect that's about right. When I'm buying beads and I just want basic good quality ones, I go for Czech fire polished beads. This vase has the same sort of feel to it: good decent quality with no frills.
Or does one of the more experienced glass boarders know better? .........
