Old unknown signed vase

Hello all, i got this vase from the estate of my grandmother. It is signed and i tried to find it online but i found nothing. Maybe someone know the producer or has some Others information, would be nice thanks a lot.

 

Welcome, Aigi! Very nice studio pottery. I think the initials on the bottom are read GB (turn the last picture 90 degrees clockwise to see that.) I have no idea who that person might be but studio pottery often stays close to "home" so you might want to ask around in the area where your grandmother lived in the 70s.

 

Salt glazed, if that helps. It's a nice lump.

 

I see FB turned 90 degrees counterclockwise.

 

She travelled around the world for many years so she could get it from everywhere, i allready asked friends who lived there. And no one has an idea. She gave me about 7 vases and they are really hard to designate but it is very interesting to check the history behind.
But now i know it is salt glazed and from the 70s that helps a lot! Thank you

 

Nice piece. Sorry I can’t help you .

 

could be Gillian bliss.

 

I watched many Gilliam bliss signatures and they are different but im not really an expert and btw thanks all who helped me so far
