Introduction:

Linseed oil with earth-pigments was one of the most common architectural paints used in the United States until it was phased out in favor of petrochemical vehicles and plastic-based binders in the 1950s. Degummed linseed oil paints are enjoying a renaissance as a wood finish, but their suitability and performance require an understanding of their properties, behavior, and parameters for use. This talk covers the basic material science of modern linseed oils: how linseed oils are made, how they dry, how they interact with substrates, and how they weather—all properties that differ from contemporary water-borne paints.
