Re: Paper negative
Loris, "Paraffin oil" or "liquid paraffin" or "mineral oil" isn't
the same thing as paraffin, that Judy was talking about, which comes
in a solid white block and is used to seal jelly jars when canning
jelly. I tried paraffin for this purpose and rejected it early on,
for a number of reasons, including that paraffin-waxed negatives were
very susceptible to scratching; mineral oil is quite different both
in application and in effect. My experience as far as stability is
that negatives oiled 15 years ago are just as the day they were made.

I'm quite confused; when I read "mineral oil", Paraffin doesn't
come into my
mind. I understand what you call "Kerosene" (Plane fuel & fuel for
in stoves... It's very good in making your car's paint shiny!) when
the words "mineral oil".
I just looked on Wikipedia because I wasn't sure I was remembering
right about the laxative part, and found a whole long list of uses
for mineral oil. One thing I hadn't known is that baby oil is just
mineral oil with added fragrance (that "baby oil" smell). No wonder
it makes my hands feel so nice.
