3 Pieces Of Art Glass

Wondering if anyone can help me identify these pieces.

1. Vase/jardinire, blue blown glass, measures 7 3/4" tall and 8" wide.

2. Cranberry vase, measures 6 3/4" tall and 3 1/4" wide. Stamped on the base wit wahat look like a P or B inside a dome.

3. Ruby vase, measures 5 1/2" tall and 5" wide.

 

The color of the first one, and the loose 'style' -your blue vase looks 1960s to me.
Carried on into the seventies and early eighties, afterwards too, of course.

 

Blue is from Empoli. I know that stamp on the cranberry, brain has forgotten it.

 

The 'dome' may be the opening in a glass furnace, or representation thereof. Could the thing inside be a swan? No other help, though.
Sorry.

 

It's annoying the bejaysus out of me!

 

The mark on the cranberry is Pilgrim Glass I think.

 

I should have guesses Italian on the first one, thanks. I have included better close-up of the mark on the second vase.
