Hello,
The "Fake Laliques" are not intentionally manufactured to be fake Lalique, but Barolac pieces identified as Lalique either perpetuating a mis-attribution they have stumbled across, or called Lalique to in an attempt to deceive less knowledgeable buyers. There are actually quite a few pieces of Barolac glass on that page, several of which I own.
If one goes to the trouble of actually producing a "fake or forged" Lalique piece, they at least bother to produce, usually poorly, a known Lalique piece, and those pieces are also out there and shown on the Lalique site I referred you to. I do not use the term forged to indicate another manufacturer's piece of glass with a spurious signature put on it.
I think attributing your vase to Barolac is pretty much a sure bet, especially if the details are well defined, and cewrtainly in light of the fact that the color is among those mentioned in the literature.
For what it is worth, I also think that an assumption that glass purchased in France, is more likely to be from France, is a hypothesis, that if used as a starting place for ID of items, will make attributions quite difficult....
As an example, I am in the US, and if I started with that assumption, I would have a difficult time attributing much of the Czech, Italian and Scandinavian glass I own. To follow your hypothesis would mean that I should assume to start that the glass I buy here in the US is more likely to be from the US, and that people in Scotland, England, Italy, etc. should all make that assumption to start....
A much better position to start from when identifying a iece of glass is the position of "I have no idea what this is or where it is from. Let's see if we can figure it out." In some cases your location, or the location of purchase can "aid" in the attribution, but it is generally not a good assumed initial position.
As an example, I have a piece of Victorian era art glass in a very organic form. I started with the "assumption" it was from the Stourbridge region of England based on it's form. I looked for over 5 years to identify it. It turns out, when I dropped that false assumption, and sent a picture to a good friend of mine, a resource I had known the whole time I owned the vase, he informed me it was Czech, by Kralik, and sent me an image of a known vase to confirm the identification. Had I simply started from scratch 5 years ago I would have sent him the image and saved myself a bunch of research time....
Simply stated, starting with false assumptions will, more times than not, lead to incorrect results.....
Maybe your Barolac vase was a post war souvenir taken home by a French soldier or tourist....
In today's world, glass from everywhere is everywhere..... the older it is, the further it has had time to travel.... I also own a pair of late 16th / early 17th Century German Roemers... I purchased them in Seattle....
