Just want you to know that I'm not being rude in answering your comments on this piece of glass, I just find it really hard to log on sometimes. Don't know what it is, but sometimes if I reboot my computer and go directly to this site, I'm able to log on. So, enough of me whining....
I was thinking that this piece is probably Chinese made, they are getting better and better in their glass houses over there that it is getting harder and harder to identify. In fact I was at WalMart today and saw some really pretty vases that looked very close to being Murano pieces, except they had a label on it saying made in China. But if there wasn't a label on it, sometimes you can't tell the difference.
Thanks for the info on how to shoot dark colored glass, I'm going to be experimenting today with your suggestions.
