the shape of your bowl looks like a Daum shape (see link),however I'm sorry I don't know anything about Daum glass and was thinking that if it were Daum it would be signed in the making of it? But I can't say that for sure. Also I can't be sure it's the same shape but it does look so.
Also your bowl is slightly smaller than the one linked to, however again, I don't know anything about Daum so I'm not sure whether these were made in various sizes. I have three Daum bowl two are similar sizes but not identical and the third is much larger. All are from the Daum Jades range but only the large one is signed.http://www.liveauctioneers.com/item/4351883
Also try looking up Daum vitreous glass perhaps? I think they did a matt uncased mottled glass that was called this. You might be able to find a colours match maybe.
Sorry I can't be more helpful.
Lovely bowl and gorgeous colours
