  Let me introduce a word here:  "Significant".  It may be true that
lead has a vapour pressure.  Ice has a vapour pressure; you can sublime
it under vacuum, a process used with great benefit to campers
(preserving food by freeze-drying).  You'd be a long time subliming lead
in a vacuum!

  The point here is that the vapour pressure of lead is very, very low;
it is not *significant*.

  This anxisty about lead presumably, largely results from concern
about lead pollution from volatile lead compounds, most notably tetra-
ethyl lead, and that mostly from its use in petrol and discharge in
car exhausts.

  Is that rapeseed oil?  Just curious.  I should have thought there were
many compounds more soluble in mineral oil than vegetable oil (rubber is
an obvious example).  OTOH, Eucalyptus oil mentioned in another thread,
behaves like mineral oil.

  If you burn it and are exposed to the fumes, it would rather defeat
the purpose ;-)  I doubt it contains lead.
