Pair Small Mold Blown Blue Glass Asian Themed Vases

Any suggestions on the origin and maker?
Thanks

 

Maybe Bristol glass?

 

The mark on the bottom is a Peacock's head and shoulders. Its from Sowerby, Gateshead on Tyne. Late 19th century, they did arguably the best mold work of any pressed glass house.

 

Thanks a bunch!!!

 

the pattern is found in Sowerby 1880 pattern book as vitro-porcelain #1188; tho' I thought Sowerby quality was much better... Sowerby called this color turquoise

 

Yep, that little mark on the bottom is Sowerby's, you can see it on this page

So, are these pressed or mold blown?

 

I like to ask the question. "If this is pressed, how'd they get the plunger out. In this case, I don't think they could [get the plunger out]. Some pressed pieces can be tooled shut, or closed, but this square top doesn't lend itself to that. I'd suggest the process involved blowing with compressed air to get that kind of detail.
