Blown oil

Description

A thickened vegetable or animal oil that has been processed in a stream of air or oxygen. Blown oils are partially oxidized and thus thicker and faster drying. Common blown oils castor, linseed, rapeseed, whale, and fish oils. Blown oils are used in paints and varnishes, but are not suitable for artist's uses because they have poor durability and darken on exposure to light.
