Ik las op Wikipedia net trouwens ook nog dat je met lijnzaadolie echt voorzichtig moet zijn wanneer je er bijv. stukken keukenpapier mee verzadigd hebt, omdat dat dan spontaan in brand kan vliegen:
Rags, cloth, and paper saturated with drying oils may combust spontaneously (ignite) due to heat released during the curing process. This hazard is greater when oil-soaked materials are folded, bunched, or piled together, which allows heat to accumulate and accelerate the reaction. Precautions include: wetting rags with water and spreading them away from direct sunlight; closing them off completely in water inside air-tight metal containers designed for such applications; or storing them immersed in solvents in suitable closed containers. Linseed oil-soaked rags were the cause of the large fire in the One Meridian Plaza 38-story office building resulting in severe structural damage, after which a decision was made to demolish the building.
