It's useful to know there is a fake Baccarat mark around. I don't know how good it (the mark) is, or if I'd recognise Baccarat anyway, but I certainly know what these bits of (yellowy) glass are!
I had a large plate with the purple flowers in it - it had quite a nice blue rim applied. I got £15 in Oxfam for it whan I was working there, I thought we were doing well!
Pretty enough sort of thing for use if you like it - and doesn't matter if it comes to grief!
