Cold Wax is an oil painting medium which is a buttery soft paste made of wax mixed with a small amount of solvent and resin. The cold wax paste is mixed with the oil paint on the palette. Cold wax adds body, transparency, and depth to the oil paint. It also speeds up drying time, increases the paint’s workability, and does not require the special ventilation of encaustic. Cold wax medium also combines readily with other mediums such as dry pigment, powdered charcoal, marble dust, chalk pastel, graphite, and oils sticks.
