This is a very complex problem, depending on the pigments and the
type and condition of the glass.  We have conducted a number of
experiments in my lab or this and I have published an article with a
summary of other treatments by other conservators and the durability
of the methods in Studies in Conservation.  If you would like a copy
send me a stamped self-addressed envelope ($2 US in postage) and
I'll send you a copy.
