Boiled oil

Description

A type of Linseed oil processed with heat and metallic driers to produce a faster drying product. Boiled linseed oil is not actually boiled but heated to about 130-150C with small amounts of soluble driers (organic salts of manganese, lead or cobalt). This treatment accelerates the drying process and makes the oil thicker. Boiled linseed oil is not suitable for artists use because it darkens when exposed to sunlight (Mayer 1969). Boiled oils have been used for industrial paints, varnishes, enamels, waterproofing, and patent leathers.
