Definitely not Murano and I don't think it's 1970s Italian airtrap. My guess would be 1880s ish Bohemian air trap

see above and
perhaps whoever made it was influenced by seeing alabaster zoomorphic antiquities?

Anik, even if this doesn't help, you might be interested in this article anyway - some interesting information on Czech glass 20th century history and artists in here

Having gone through Jindrich's list of artists for the B's I couldn't see any other maker that might be relevant.

Right - I'm just adding this thought.  Most likely a complete red herring and I cannot find anything that might remotely make a link to the style of your sculpture apart from the initials.
But, for the initials Jaroslava Brychtová came to mind.  For the style, nothing I can find.  However, this is 1970 so maybe, just maybe, it was an experimental piece perhaps?
Then I found this book with her signature in it

and this is the signature page signed by her

and that J and the kind of wobbly type B well maybe not the B so much, but the J reminded me, so meant I  had to say something ... just in case iykwim?  Anyway, probably a complete red herring as I said, particularly given the style of the glass.

Lovely bowl,  but not Skrdlovice.  The base would be highly polished and flat, and the edge of the base would be slightly shaven.

Thanks Fred I was thinking Burtles and Tate, the only other piece I have seen in this colour was a swan by them.
