Re: [ATM] Does exposed Pyrex lose polish over time?

[Mark Cowan <toolontop@yahoo.com>]

What I'm thinking is the chemical properties of
freshly exposed glass after polishing are different
from those properties after it's had a chance to
interact with the atmosphere and/or whatever else it
comes into contact with.  But I can't quantify it. :(
