I don't have the Heiremans book, but I do have a Scarpa book. The blue one is close to model 38 in the Scarpa book, but that piece has a foot and the ends of the bowl are folded slightly upwards as well as the sides. If it were Venini and Scarpa, it would be marked, although the acid stencil mark is often very faint.
A bollicine was made by adding potassium nitrate to the glass, which creates fine, carbon dioxide bubbles. Pulegoso had much rougher bubbles. I've read that pulegoso was made by adding kerosene, but I've also read that it was sodium carbonate that was added.
Here's an example of what I think is a Scarpa "submerged a bollicine" I have. Not great pictures but you get the idea.
