The raw linseed oilwill definitely soak in better and not produce as much shine. Hard to find except in art supply stores in small quantities for outrageous prices. (US only, other countries it's naot as big a drama.)
Non-toxic to boot!
Ooorr...in the health food section of some grocery stores for a somewhat better price with a fancy name. (linseed oilis made from flax seed):
It's actually quite tasty. I like it on Southern -style cooked down green beans. Less artery clogging than the lard...
Keeping it in the 'fridge does prolong shelf life- if it doesn't get eaten! The last of the Grumbacher's linseed oil has started to thicken, but the Whole Foods linseed oil is still good. (Did have to buy a bigger bottle for kitchen use, as this test bottle was draining quickly...)
