I've just gone through over 1000 patterns on a website and have done google searches too countless to mention. The closest match I've found is hobstar but that's not it. Any help would be greatly appreciated.
I see several pattrns that are very close in the collectors encyclopedia of depression glass, but none exactly like that. Can you take more pics ? Its a beautiful piece whatever the case is. The mystery continues ? Daisy number 620 by indiana glass company is close but not quite. Could be a modern reprduction of No.618, pineapple & floral indiana glass company, 1932-1937. Cant quite seem to get an exact match.
It is iridized -- the flash has somehow hidden it. I've looked further but have gotten nowhere. When I get home after the holidays I hope to be able to search more thoroughly.
Possible good news was the the makers of carnival glass used a process of iridescence to simulate Tiffany glass.
Wouldn't that be nice. Tiffany should have a mark on the bottom.
