The two vases look very much alike to me in that they have the same overall shape, and have been worked using the same techniques: a ruffled top, where some of of the lips have been left more upright and others pulled down or out, a tool has been used to push the glass near the top, there's a slightly different shaped push at the bottom, and another tool created mark on the main part of the body. I'm also allowing for the variation that's inherent in the process. Shannon's picture is better and has more light in it which shows off the colour and the bubbles, as well as making it look like a better quality vase. It's the bubbles in the first vase that make me think that it could be Chinese, as I haven't seen bubbles like that in any European vases.
What I get from Shannon's recent contribution is that we have to add China to the list of place where these vases are/were made. It's relatively easy to identify the Czech Skrdlovice pieces because of the colours, the workmanship, and the use of the compressed air to soften the pulled and pushed sections. Yet there were (probably still are) other factories in Czechoslovakia and the Czech Republic doing pieces not unlike this. Marcus suggests Chribska, for example. Add Murano, and Sweden (apparently Aseda produced very similar looking vases), and Chalet in Canada and it often becomes difficult to identify a specific location as the origin of any vase.
I suppose my personal view is that it doesn't particularly matter at that point. I don't think a Murano vase is any better than a Czech vase (certainly not a Skrdlovice, obviously my favourite), and Aseda vase, or a Chalet. From the look of Shannon's vase, I'd put the Chinese vase in last place, but not by that much. For fairly generic pieces, which these are, I think, some times I feel we'd be better off focusing on the virtues of the piece itself, more than trying to tie it to a specific location. Would I like or value (aesthetically not monetarily) Shannon's original vase more if it were proven to be Murano? Of course, that's a very specific collector's (me) point of view. I'm sure sellers and other collectors would have a different viewpoint.
There was another thread on a similar type of vase, but with a very plain mouth, that you might find interesting.
