A propos of oiling paper, my tests of every single "oil" in this house,
about 12 of them, from kitchen and cellar, from olive & sunflower to
castor and lemon (for furniture) changed density as it dried, which
started as a rule by the next day. That is, the paper lost translucency &
began wending its way back to opaque (as measured by densitometer).
I described this in P-F #8. The only relatively permanent way of
transparentizing paper I found was with bee's wax. Parrafin wax was
nearly impossible to apply without mottling. Kate mentions parrafin oil,
but as I recall that's a term (originally I think English) for something
other else, not parrafin, but I recall not what...
