Description

Linseed oil that is expressed from steam-heated seeds using a screw-type or hydraulic press. This method extracts the oil more efficiently than cold-pressing, but it produces a lower quality paint. Hot-pressed linseed oil is a light brown liquid that is slightly turbid due to the presence of moisture and proteins. It is usually refined to remove the impurities. Most of the commercially produced linseed is hot-pressed. It is used in industrial paints and furniture varnishes.
