This collection of 60 colors has a thick cream-like consistency that is perfect for easy brushing or carving with a painting knife. Colors are mixable with traditional linseed-based oil paints and can be thinned with Da Vinci's Alkyd Paint Thinner to lower viscosity and increase transparency. More pigment and thicker consistency. The first professional Fast Dry Alkyd Oil with no compromise in pigment load and no strong alkyd smell—simply superior to any fast dry oil you've ever tried. Thin film dries to touch in 24-48 hours, depending on the pigment.
