Hi Dave,

Funny you should ask!  Eric Tulsky and I are both on the UC Berkeley
campus, and I mentioned the glass issue as the single first topic that
lured me into the APD a month ago.  By then this had become a passe topic,
but still oh-so fascinating to me.  From his interested reply and the fact
that he appears to be a chemist of some sort (am I right Eric?), I think he
may investigate the film on my glass.  This is a very interdisciplinary
collaboration!  I'm sure if he makes any determinations they will be shared
with all.

I'll reiterate my position that the deposits are within the pores of the
glass, hence impossible to remove by non-invasive scraping and scrubbing.
