Grumbacher"s Max Oil Colors are identical to conventional oil colors, with one major difference ? Max Oils thin and clean up with water. With Max Oils, there is no need for special brush cleaners, turpentine, or mineral spirits. Max Grumbacher"s professional-quality, water mixable oil colors are made from the same pigments and linseed oil as Grumbacher Pre-Tested Oils, and they have comparable drying time. Max Grumbacher colors can be intermixed with any other oil colors or oil painting mediums, and they can be varnished after 6 months. Use at least 70% Max color, and no more than 30% of regular oil colors or mediums to retain the water miscible properties of Max Oil Colors.
