Hi all,
I know there was a thread about this pretty recently, but I can't find it.
Is there a way to quickly and easily determine whether a mirror is Pyrex, without resorting to density measurements? The one I'm looking at has a greenish tinge, but it is very faint. IIRC plate glass has a rather strong green tint. Is that always the case? Will it only be a completely reliable determination if I measure density?
Thanks,
Mike
