I picked up a very interesting Loetz vase. I believe, but am not positive, that it's from their Metallin line. It's a very interesting color, and aside from the Loetz Octopus pieces, is the only other Loetz piece I've seen marked with a reference to a Patent.
I'd be interested in comments from other Loetz collectors/dealers. I've posted several pictures and other details here: http://www.glasscollector.net/Loetz/LoetzPaperweightStyleVase.html
