[Woodcarver] refining linseed oil

[Ed Ertel]

Linseed oil is a natural oil pressed from flax seeds. 
By itself, it will take possibly months to dry.

While boiling linseed oil could change it's chemical
properties and make it dry quicker, the "boiled"
linseed oil you buy actually has chemical additives
added to make it dry more quickly.  Usually, these
additives contain heavy metals, so "boiled" linseed
oil is not suitable for anything that will come in
contact with food.

You can purchase commercial dryers to add to oil based
paint.  One readily available in small quantities
should be "Japan Dryer", which used to be available in
art supply stores.  (The oil paint used by artists is
simply pigment blended into a linseed oil binder. 
Earth colors will dry more quickly, but lighter
colors, like white, have more dryer added to the paint
at time of manufacture.)

I haven't painted in years, but a good art supply
store should have "Japan Dryer" or a more contemporary
equivalent.
