Linseed Oil is extracted from the seeds of the flax plant, which are pressed and lighty toasted. Linseed Oil creates a very good paint film which is hard, resistant and flexible. Linseed Oil also reacts well with additives and is by far the easiest oil to make oil colors with when combined with pigment.

The disadvantage is that it will slightly yellow. One strange phenomenon of Linseed Oil is that in the dark the oil darkens quite a bit but when exposed to sunlight it will lighten.
