Bristol Glass Vase - Age

This vase is one of a pair. Hand Blown glass, white with lavender decoration, clear base. measurements 6" High, 5.5" opening diameter, base 3.25" diameter. I know nothing about it - age, country of origin, is the building an unusual decoration.
TIA Sue

 

I cannot get the bottom photo to upload. Keep getting a message that it is too large. I keep resizing it, same message. will take another photo.

 

I thought Bristol glass was that translucent white throughout. Yours seems to have a clear glass bottom, which suggests that the interior white is a flashed coating. Don't know if that's true or if it makes a difference.

 

Thank you Moreotherstuff. Not Bristol, the bottom is clear.

 

Arg. Bristol is a massively misused term, just like MAry Gregory. This is cased milk glass.

 

Thanks OwnedbyBear ! New Keywords to use in search. Is this vase old and what country of origin.

 

I'd think late 19th into early 20th. The house looks maybe German, so perhaps Bohemia.

 

OwnedbyBear. Thanks again.. Other than mistaken them for Bristol Glass, my hunch that they might be European and Victorian was correct. Have a great week.
