A drying oil used in artist paints that is obtained from the seeds of the common flax (''Linum usitatissimum'') plant. Linseed oil contains the following fatty acids: [http://cameo.mfa.org/materials/fullrecord.asp?name=linolenic acid linolenic] (48-60%), [http://cameo.mfa.org/materials/fullrecord.asp?name=oleic acid oleic] (14-24%), [http://cameo.mfa.org/materials/fullrecord.asp?name=linoleic acid linoleic] (14-19%), [http://cameo.mfa.org/materials/fullrecord.asp?name=palmitic acid palmitic] (6-7%), and [http://cameo.mfa.org/materials/fullrecord.asp?name=stearic acid stearic] (3-6%) (Serpico and White 2000). The drying property is due to the unsaturated bonds in the linoleic and linolenic groups. Linseed oil is the most important and largely used oil for paints and varnishes. It produces a hard, insoluble film when it dries. The yellow-gold color oil is commercially extracted by various methods. The seeds can be crushed in hydraulic or screw-type presses to produce cold-pressed oil. The same process performed on steam-heated seeds produces hot-pressed oil. Cold-pressing is a less efficient manner for extraction, but it produces a higher quality artist paint. Many types of aging, refining, and bleaching procedures have been used to purify the oil and make it dry faster. Linseed oil is used in [http://cameo.mfa.org/materials/fullrecord.asp?name=paint paints], [http://cameo.mfa.org/materials/fullrecord.asp?name=varnish varnishes], [http://cameo.mfa.org/materials/fullrecord.asp?name=printing ink printing inks], [http://cameo.mfa.org/materials/fullrecord.asp?name=synthetic resin synthetic resins], [http://cameo.mfa.org/materials/fullrecord.asp?name=oilcloth oilcloth], [http://cameo.mfa.org/materials/fullrecord.asp?name=linoleum linoleum], and [http://cameo.mfa.org/materials/fullrecord.asp?name=soap soaps].

Description

A drying oil used in artist paints that is obtained from the seeds of the common flax (Linum usitatissimum) plant. Linseed oil contains the following fatty acids: linolenic (48-60%), oleic (14-24%), linoleic (14-19%), palmitic (6-7%), and stearic (3-6%) (Serpico and White 2000). The drying property is due to the unsaturated bonds in the linoleic and linolenic groups. Linseed oil is the most important and largely used oil for paints and varnishes. It produces a hard, insoluble film when it dries. The yellow-gold color oil is commercially extracted by various methods. The seeds can be crushed in hydraulic or screw-type presses to produce cold-pressed oil. The same process performed on steam-heated seeds produces hot-pressed oil. Cold-pressing is a less efficient manner for extraction, but it produces a higher quality artist paint. Many types of aging, refining, and bleaching procedures have been used to purify the oil and make it dry faster. Linseed oil is used in paints, varnishes, printing inks, synthetic resins, oilcloth, linoleum, and soaps.
