First thought was that I have seen a Per Lutken bowl from the early 50s somewhat similar - the thickened rim, the vaguely "Fionia/Selandia" shape. I have one similar but with lots less bubbles. Also the outer green seems very close to Holmegaard's "Antigron"(hope the spelling's right - but it is close".
Second thought was that Galliano Ferro were particularly good with controlled bubbles.
Third thought was what would the colours look like against a white background, away from the edge of the house(which accentuates the blues) and preferable not in direct sunlight so shadows don't confuse too much. That "smokiness" is intersting and I associate with Murano.
