Hi Lynne,
Yes, I know that French manufacturers did this type of "opaline" glass with hand painted designs also.
As I think has been said, this style was fashionable for quite a while, & widely made, in the Victorian era.
The quality varies a lot, but this vase looks very good.
I feel that this one is a Bohemian though, due to some very similar items pictured in Truitt's "Collectible Bohemian Glass 1880-1940".
