If you're looking to purchase milk paint already colored, check out our 56 different milk paint colors. Unlike Milk Paint, Pigment Powders do not contain binding agents; these powders are pigment only and are mainly composed of non-toxic iron oxides, natural earth powder and milled minerals. Use this colorant additive to add to concrete, Pure Tung Oil, viscous mediums or others to transfer color to your world. Pigment powders provide color, texture, opacity and depth to your paints and coatings. The higher the pigment concentration in a paint or coating, the greater its durability, coverage, hiding power and ability to resist fading over time. Pigment Powders are packaged in a jar. You will receive 16 oz. by weight of the powder in a 20 oz. by volume jar, because the specific densities/weights vary by color pigments.
