Huh! In Akro Agate glass, when you say aventurine, you're talking green. But when I search on aventurine Murano, it's gold here.
Could I say "Black aventurine Murano bowl (AVEM, Fratelli Toso, Nason, Moretti?)" That would allow the people looking for Fratelli Toso, say, to at least find it and use their own judgement. Or do collectors hate that so-and-so with a question mark thing?
"Black aventurine Murano bowl with corkscrew"?
I've got an auction to go to (might be some good stuff, but might not, so fingers crossed), will check back on responses later this afternoon...
Okay, here are some better pictures, taken outdoors with trees shading the deck. (I'd thought that taking utdoor pictures of glass was a no-go, but now I'm seeing my problem was taking the pictures in full sun.)
I think this is the best of the new batch - you can clearly see the corkscrew, the gold swirl, and the white squiggle underneath:http://www.crosslink.net/~jlharmon/murano2h.jpg
I also got a picture of the bottom. There are four little blobs of gold - I thought at first they were just a production error, but now I'm wondering if maybe it's a very smeared maker's mark?http://www.crosslink.net/~jlharmon/murano2f.jpg
Other pix from various angles, for the completists:http://www.crosslink.net/~jlharmon/murano2d.jpghttp://www.crosslink.net/~jlharmon/murano2e.jpghttp://www.crosslink.net/~jlharmon/murano2g.jpghttp://www.crosslink.net/~jlharmon/murano2i.jpg
So - does any of this help?
