Canary Yellow -- Murano Art Glass Bowl

Really bright yellow Murano Bowl (or Ashtray at one time) with controlled bubbles. The bubbles do vary in Size. Base has very good wear. Heavy, and not sure how you would call the shape....maybe like a Disc shape (?). If it was an Ashtray, it has no cig slots. Maybe it was for a Pipe?????

It is:

~ 2.75 inches Tall
~ 7 inches wide (AT the widest point-middle)
~ Opening is only 5 inches wide at the top
~ Weight is 2.14 pounds

Not sure if this is true or not -- but heard that the Color yellow in Art glass is more Rarer. Anyone else know? This does not have a label, but I did find a blue one exactly like this with a BLUE and GOLD round label like this one here (except in Blue). Generic label...see last pic posted here

It is simple, bright....and beautiful I think. Thanks for looking!
