Um, it did have some ashes in it when I got it. I just thought that maybe someone used it as an ashtray. I hope they were only cigarette ashes because I washed them down my kitchen drain.
Lustrousstone, it isn't really coffee colored. It's the exact color of a green olive. But I do think that it is opaline. It looks like opaline glass.
Thanks to everyone for all their suggestions and attention to this item. I'm so glad I found this forum!! I'm learning so much about glass from these boards!! I didn't think I 'collected' glass. But as I took a good look around my house, it's amazing how many glass items I've surrounded myself with. I guess I am a collector after all
I'll be here a lot. I may not post much because I don't know a lot. But I'll be around reading other people's posts and learning from them.
