Paint with milk-based pigments for fast-drying, velvety finishes with unique matte charm

creativecrafty$$ medium1 hourdifficulty 2/5

Casein paint, made from milk protein, offers a unique medium between watercolor and acrylic with exceptional handling qualities. It dries quickly to a distinctive matte velvety finish, water-soluble while wet but waterproof when dry. Casein allows layering, glazing, and scumbling techniques while maintaining crisp edges and luminous colors. Used by American Regionalist painters and contemporary artists, casein creates a warm, sophisticated aesthetic. The medium is affordable, non-toxic, and perfect for artists seeking a vintage or nostalgic aesthetic.
