Oil used to make oil paints comes from several sources; the most common used is linseed oil, made by boiling the seed of the flax plant. The oil is then mixed with pigments to attain color. Common pigment bases include lead bases and cadmium bases. In recent times, synthetic pigments have become popular; however many are not tested well for their lightfastness.

  2. Wash your hands well and avoid unventilated rooms when painting.
  3. Paper or rags soaked in pure linseed oil are known to spontaneously ignite. Be sure to soak the rag in water or seal it in a bag of water or metal can.
  4. Although synthetic pigments are popular, there are no good synthetic pigments to replace the cadmium colors.
