Pumice, Linseed oil, Creosote (Wallingford)

Cleaning out the paint shelves:
  Two boxes of Pumice, feel mostly full and loose: Rubbing pumice and pumice aggregate. Don't know the difference
 Two cans of linseed oil. I'm keeping a third can. Still sloshes around. What can go wrong with linseed oil?
Can od creosote, feels about half full.. Not sure if this stuff is still legal?
