Scandinavian dish?

Anyone happen to know the maker of this one?
Many thanks!

 

Here is another close up

 

And the bottom of the dish

 

At first I thought it could be Treasurecraft, similar style, but now I just think it's studio pottery with glass melted into the center of the bowl as decorative glaze.

 

Thank you!
You've described it so nicely!

Ok which basis you usually decide about studio pottery origin? Because there is no known maker or?

Thank you!

 

Treasurecraft brand was typically a type of souvenir pottery cast from ceramic slip and painted. Yours is decorated much like some Treasurecraft of the mid-1900s. However, Treasurecraft is generally very well marked.

Yours was hand thrown on a potter's wheel, hence it is studio craft art, decorated in a mid-century-modern style.

It appears to be missing the lid. Do you have it?
