Grumbacher Max is one of the first water-mixable oils. A professional line of 57 colors, Grumbacher Max water-mixable oil colors are solvent free and thin and clean up with water, but maintain the chroma, workability and lightfastness like a traditional oil color. There is no need for special brush cleaners, turpentine, or mineral spirits. Max oils employ the same finely ground pigments and superior quality linseed oil as our renown Pre-tested paints and dry at a comparable rate. Max colors will retain water miscible properties when intermixed with traditional oil colors or oil painting mediums, as long as the artists uses at least 70% Max color and no more than 30% of regular oil colors or mediums. This paint formula eliminates the use of harsh solvents and is ideal for those sensitive to chemical fumes. Made in the USA.
