Linseed oil has a number of uses in oil painting. It can be used as a paint binder ingredient when mixing colors from powdered pigments, in oil painting medium recipes, and added directly to oil paints to make colors glossy and fluid. Made from the finest quality purified alkali-refined linseed oil. Linseed oil can be pre-diluted with Turpentine, Grumtine, or Pre-tested Odorless Paint Thinner. Made in the USA.
