If it's of any interest we experimented at Silverprint with glass plates (10
x 8) by coating them with Silver gelatin (liquid light or whatever you call
it).
It adheres quite easily to the glass with or without subbing. Its effective
speed is about 2 Iso and being paper emulsion is very contrasty. It is
described in Martin Reed's book "Silver Gelatin" which is in course of
being reprinted. Most archive nitrate movie film has been transferred as it
leads to the archive being blown up. It appears according to Martin that
cellulose nitrate is only used by those with a strong death-wish.
