Linseed oil and boiled linseed oil are both derived from the dried, ripened seeds of the flax plant (Linum usitatissimum). However, they are processed differently, which results in some differences in their properties and uses.Linseed oil is a raw oil that is obtained by cold pressing the flax seeds. It is a natural oil that has not been chemically modified or treated in any way. Linseed oil is used as a dietary supplement and natural remedy, as well as in the production of paints, varnishes, and other products.
Boiled linseed oil is a type of linseed oil that has been treated with chemical additives, such as metallic dryers and thinners, to make it dry faster and easier to apply. Boiled linseed oil is often used as a wood finish because it penetrates deeply into the wood and helps to protect it from moisture and damage. However, it is not as durable as some other wood finishes and may require more frequent maintenance.In general, linseed oil is considered to be a healthier and more natural choice than boiled linseed oil, due to the chemical additives used in its production. However, boiled linseed oil may be a more practical choice for certain applications, such as wood finishing, due to its faster drying time and easier application.
