Featured midcentury Glass bubble bowls

These bowls are about 5.5" at widest and have polished bottoms. Controlled bubble is an understatement. These have extremely tiny uniform bubbles. I'm assuming Italian. Any specific ideas? Thanks

 

Bullicante is the word you seek. I'd think Italian.

 

What a nice $et!

 

Owned, you are in rare form today!!

 

I will NEVER understand how they do the 'controlled bubbles' thing......

 

Ashtray set.

 

If I remember, those bowls have a wire mesh imprint, not controlled bubbles.

Picture a pad of small nails, point up, one every quarter inch. The glass blower lowers a gob of hot glass on the pad, imprinting the points of the nails into the glass. He then lifts the gob off the nails (it's got lots of tiny depressions in it) and gathers another layer of hot glass over the gob, trapping the air inside the nail point holes. The pattern is "controlled" by the arrangement of the nails.

Thank you!

A little more history I looked up from Glass of Venice
The bullicante technique became famous during the 1930’s thanks to Archimede Seguso. Parting from his famous sommerso technique, Seguso took it to another level by taking advantage of the thickness of the glass. By using a more viscous composition, he found a way to leave small incisions unaltered and empty, in spite of covering them with another layer of glass. And while working on other light artworks like lamps, he figured the spiky tool he used on those lamps could also be helpful for the creation of dents. Seguso therefore figured out it was the size and shape of the metallic spikes that determined the position and depth of the pattern impressed on glass. He started experimenting with up to six layers of glass, trapping “bollicine” (bubbles) of air inside every layer. These bubbles reminded him of the bubbles in boiling water, thus calling this technique “bullicante” which literally means “boiling”. After mastering the technique, he went as far as decorating the inside layers with gold leaf and other colors, making each piece even more valuable and unique.

 

So, they aren't bullicante?

 

WOW!!! Thanks @Cherryhill!!!......ALWAYS something to learn here, and ALWAYS someone to teach it!!!!! BEST SPOT to land to learn stuff!!!!!

 

Yes, they're bullicante.

 

My error, I thought I'd seen some that were wire grid indentations. Still think so, just not these.

 

Hey, I'm no total expert, they just look it to me, rather than the mesh method.

 

The mesh ends up looking like a waffle?
