What is Boiled Linseed Oil?

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.

It is a popular choice for wood finishing because it penetrates deeply into the wood and helps to protect it from moisture and damage. Boiled linseed oil is made by heating raw linseed oil, which causes it to polymerize, or cross-link, resulting in a thicker and more viscous oil. The chemical additives in boiled linseed oil help to accelerate the drying process and make the oil easier to apply. Boiled linseed oil is typically applied to wood surfaces using a cloth or brush and may require multiple coats to achieve the desired finish. It is a relatively inexpensive wood finish, but it is not as durable as some other finishes and may require more frequent maintenance.Boiled linseed oil has a number of potential uses, including wood finishing, leather conditioning, and rust inhibition. However, it is not as healthy or environmentally friendly as some other wood finishes, due to the chemical additives used in its production. Raw linseed oil is generally considered to be a healthier and more natural choice.
