Oh -- just that regular glass probably blocks "a lot" of ultraviolet, but probably blocks none of it completely. Just like a decent set of earplugs can block out sound, but not entirely. So, people commonly say that glass blocks ultraviolet. Certainly, it's bound to pass a bit of it (a tenth of a percent? I don't know). Perhaps what John's describing is that enough does get through that folks have found it worthwhile to modify the glass to block more than it already does, I think. -Greg ------------------------------------------------------------------- Unsubscribe? mailto:type3-request@vwtype3.org, Subject: unsubscribe
