I think there is a sort of "cult following" of these quirky Poliarte designs
they were established in 1968 by Albano Poli
recently I purchased a huge chandelier that is almost certainly from Poliarte and is 25kg+ of hammered Murano glass and brass
I posted photos of it on my Instagram but not here yet
Ardy, your advice about buying all pendants is "spot on", you get much more glass for the money as opposed to buying vases etc and it is probably easier to identify these pieces for a newbie like me
