Art Pottery Vase, help with mark & type of glaze please

Hi,
I'm hoping someone can help me identify the mark on this vase, and if possible the type of glaze...appears to have jellyfish floating in it, at least to my eye. Thanks for looking!!

it's crystalline glaze

Thanks so much!! I very much appreciate the info:)

looks like a porcelain body so that might be the combination that will lead to a Google id

It's a style popular with Chinese manufacturers. The mark is similar to a style used by Dennis Coulden (deceased). My gut feeling is it's Chinese pretending to be studio pottery but I could be wrong.

I have seen the mark several times so I doubt it's an American potter

The poorly finished base compared to the wonderful glaze effect, together with the font of the lettering leads me to agree with Naomi's gut feeling. It looks very recent too.

Thanks so much everyone for your input:)
It is greatly appreciated!
