A beautiful and unusual vase David
Thanks for showing it to us - there seem to be a lot more companies out there that did the handkerchief vase than I at first thought.
I have a few with old labels saying Foreign to base which are attributed to Chinese or Czech 1970s
I wonder about your vase though - I am interested in pieces made by Chance while they were making the transition from the old 'Aqualux' glass which was thicker than 'Fiestaware' - I don't know if Chance made handkerchief vases pre 1951 (Fiestaware), I do know they continued to use Aqualux for vases (rolled, ribbed) along side the thinner glass for some time.
Sources tell me that Chance made 'Aqualux' handkerchief vases right up until the late 1960s while they had phased it out for other products?
Your vase looks like red 'Aqualux' with a thinner opaque glass outer, gilded rim - I think it looks so Chance in shape and form.
It could be a pre 1951 piece, late 1940s - 1950
It is very intriguing
