Anne, thank you for letting me (and everyone else) know.
I personally feel the point of attribution's reliability and spreading only correct information in general is very important and certainly cannot see anything rude in taking up this example as it as such was a good one. This is a global forum and for many of us this is only about glass, nothing personal.
In case you feel it is okay to leave this thread as it is (i.e. with your above message included) although future readers do not have the possibility to evaluate themselves if I really was rude or not, I don't mind. For me this is about glass.
PS. Really sorry, Pamela, if I hurt your feelings, nothing personal. I still feel I had a point.
