These spatter glass, multi-coloured hand vases are often referred to as Murano and were probably produced in the later 1900's (perhaps in Romania according to Marinka Bozzec - hand vase expert) and were popular in England. They seem to be similar in shape/mold to the "chunky" hand vases produced in the Victorian era.
We purchased this unusual green vase at an antiques fair in London, England.
This pair of blue vases (below) were a find here in Canada at the Aberfoyle Antiques Market south of Guelph, Ontario.
Murano or not, I love them!
