Hi Christine
It was confirmed as Olympia and it also is a well documented Loetz shape. I'll find a ref for it on here in a mo.
I have had one other also a Loetz shape, in the same finish/colour exactly, that I sold, and I have yet another large vase here that is also Loetz Olympia but doesn't have that crackle finish iirc...I'm going to dig it out in a minute but I'm fairly sure it doesn't. That one is uranium glass whereas this one isn't and they are different to each other, ref the colours and iridescent highlights too .
