Oh it helps. I think anyone with labelled glass should have an obligation to post it, lol.
Like the Kunsthandwerk vase i posted, if it weren't for the label I'd be non the wiser & wouldn't have posted it or even bought it come to that. But if it helps one person its worth it. I posted the kunsthandwerk vase on another site & it taught someone, who had no idea beforehand, that the same company made glass as well as pottery. They thought the label had added from something else at first.
