Boiled Linseed Oil

Linseed oil is something that is available in every grocery store but is hated by many people for its strong odor and flavor. But the very reason it's kept in stores because it has a great utility value. There are number of uses of boiled linseed oil from oil painting to wood finish and from varnishes to inks, all of them need boiled linseed oil to get the desired output. Linseed oil, also known as flaxseed oil, is a natural vegetable oil collected from flaxseed that are crushed between heavy steel rollers. The crushed paste is then heated with steamers and then made to go through screw expellers or hydraulic presses that separate the rich linseed oil from the solid paste. The solid by-product is one of the high protein substance that is used as food for farm animals. The obtained oil is later processed or heated and such oil is known as boiled linseed oil. To know more about its uses, read on.

Linseed oil is essentially a drying oil as it polymerizes into a solid form. Due to this quick drying quality, it is used extensively for many chemical and furnishing works.

Wood Finish: Due to its polymer forming properties, linseed oil is used to polish the wood furniture. Traditionally, raw and cold linseed oil, which was slow drying, was used to polish wood furniture but that process was time-consuming. But, boiled linseed oil dries quickly and hence makes the polishing process less time-consuming. This oil also makes the furniture resistant to dents and scratches and it's very easy to repair such a polish. It gives a shining look to the wooden pieces. But, with the rise of synthetic chemicals the practice of boiled linseed oil wood finish is declining.

Paint Binding: Boiled linseed oil is used in oil paintings. This oil is mixed with basic paint, thinner, and a dryer. It provides oils paints with more fluidity that allows them to form level when applied on the surface. It also makes the paint more transparent and glossy. After the paint is applied, the thinner is evaporated leaving the oil to react with oxygen which results in the formation of a tough film that gives a shiny appearance to the surface.

Putty: Putty is like a special cement that resembles clay or dough, used in domestic construction. It is used to repair the sealant or fillers, such as, filling holes and cracks etc. If the putty is getting hard or stiff, a little amount of boiled linseed oil can impart some fluidity to the putty making it easier to apply and serve the purpose effectively. Linseed oil also adds the glaze to the putty that makes the glossy putty which is generally used in modern furniture to get the desired shining look for caulking areas.

Other Uses: Linseed oil is also used in linoleum, wood preservation processes, varnishes, enamels, resins, leather treatments, oilcloth, concrete, printing inks, liniments, soaps, and industrial lubricants, animal feeds, caulking compounds, earthen floors, polishes, textiles, animal care products, etc. It is also used to harden papers and fabrics for their further multiple uses.

These were some of the boiled linseed oil uses. Boiled linseed oil should not be used for consumption unless it is mentioned as "food grade". Only raw, unprocessed, and natural linseed oil should be consumed as it is a great nutritional supplement containing essential omega-3 essential fatty acids that reduce the risk of heart diseases.

Boiled linseed oil cannot be used solo but it is an important ingredient for many products that are extensively used by humans.
