Subject: [pure-silver] old kodak paper identification
I have this box of 11x14 Kodak paper that is marked exp in
1966 and I
wonder what type of paper it was.
It is called AD-Type A•1 light weight paper (single weight)
It has a very beautiful smooth natural white paper backing
and a nice
very lightly textured gloss surface.
I don't have any hopes of printing silver on it, however I
am finding I
can coat the back of it pretty well with platinum/palladium.
Also it
makes a very nice drawing paper. I have been fixing it out
and washing
it before doing anything with it.
thanks for any help or your time

Ad type was made for making mailable material like
advertising and greeting cards. It is coated without a
baryta layer so that it can be folded without cracking. I
don't know what sort of sizing was used in place of the
baryta. The emulsion was similar to Azo and came in 6
contrast grades.
A indicates the Ad Type surface and 1 is the contrast
grade.
