I bought a couple of dozen glass flower corollas a few years back, but now have abandoned the intended project. Thinking of selling them, I started photographing them & musing on their origin. They are white glass flecked with burgundy, cased clear, & individually made & thus variable in shape & patterning. Basically, they weigh around 95g each & are "life size" if you think of a lily, which the corolla closely resembles. They came with some tiny threaded brass type beads, intended as flower centres but lacking anything to which they should be attached. I thought about Murano & have seen so-called chandeliers with flowers pretty much identical, dating to the 60s or 70s. I'd be very grateful if anyone with a greater knowledge of Murano than I (actually quite easy) could give an opinion. Dimensions are around 11cm max diameter & 3 deep.
