Featured Fancy Raspberry Red & Clear Sommerso Vase with Flipped Ends

Okay, probably not good terminology but I'm trying to figure out who made this heavy, hand-blown (mouth blown?) vase. It's almost 9" high (23 cm) and the clear base and sides are solid. There are no marks, bottom is polished.

Image search brought up Italian and Swedish designs. Does this seem to be the work of a particular maker? And would sommerso be a correct term? Or only IF this is Italian.

Many thanks!

 

I found the same vase in different colors attributed to Luigi Onesto; pieces attributed to him do come on the pink/clear sommerso style. The listing does not show any signature.

Yes to Sommerso meaning sunken or submerged - my first thought was Chalet glass from Canada but Cusioser is probably correct about Onesto. Some Chalet was signed - but I have come across numerous pieces that were not.

 

Oh, thank you! I'm not familiar with Chalet so I will look. Sommerso sounds good, so I'll use that in my search!
