Featured French Rococo Wine Glass... possibly?

Hej.
I'm not the strongest in antique glass, but this one seems like a good one. I was told it was french from the 1700's, but never one to take a seller on his word I though I might swing it by you clever people just to be sure. It got all the pointers I know for a good piece of old glass, but again, not my strongest side. Any help would be apreciated.
Also, I got a ton of pictures of it but they are all too big to post aparently? It would only allow me to put that one picture in my post..

 

Maybe you could list the observations you have made already so we don't have to go over it again? We can't tell how it sounds when tapped, for instance. Imagine you have done this. What was the result?

 

What capacity is it? That's often a clue. Base? Pontil? Is that a folde rim? Does it look grey or clear in light?

 

Sure.
The glass have a gentle ring when tapped, like a silver bell almost. Its rather thin glass, the bottom of the foot is folded in under itself. The glass have many subtle bubles and impurities, particularely in the stem and foot. The glass is not even, as in, the rim at the top is not perfect and the stem is slightly off. The engravings are rather primitively made, I do engraving myself with a diamond tipped rotation carver, and these engravings are very obviously not made this way.

 

I'm afraid my english glass terminology is not the strongest as its not my first language, so I'm not entirely sure what you mean by pontil. But its more grey than modern glassware, a tiny bit cloudy but not much. The foot is folded in on itself if thats what you mean by folde rim?

 

More grey usually means earlier and yes, if the foot is folded in that's a good sign. The pontil is the area on the base where the glass blower broke off the rod.

 

Oh then yes the pontil is very visible, it havent been grinded down but seems like they padded it (?) or something, so there are no sharp angles on it

 

I took the pictures with my camera, my phone couldn't really capture the glass properly, so almost all the pictures are close to 2 mb

 

ahh there we go, well I've never been good with computers either

 

I have no way to guess it's nationality, my loss, but it's older than 1850, possibly older than 1800.
The pontil may have been fire polished, or touched with a hot iron rod to smooth it out.

 

I'd agree it may well be early 19th. It looks a bit too big for 18th. That cut looks more Bohemian than French.
