I couldnt resist this in cabinet of charity shop, i knew it would glow brightly under u/v,
and does it

(glows in daylight/flash also!)
Probably Murano, but put it on general Glass board first. Perfect condition,
A blob of dark blue glass in base, surrounde by inch of bubbles. 2" tall, 4" wide, sort of 3 sided/oval,
maker anyone?
Cheers
Andy

(if opinion is Murano, please move to Murano board,thx)
