Re: Paper negative
My comment refers to "paraffin" in its US usage, not "paraffin" as
the same thing as kerosene, of course. Would be nice if we all
called things by the same name.

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 I see
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.
