Jasart Byron Iridescent Medium adds a pearlescent effect to your artwork and acrylic paints. Paint over your dried artwork for an overall pearlescent effect, add to acrylic paint to create custom pearlescent colours or use as a iridescent impasto medium to build texture when applied thickly. Simply use a paint brush, pallet knife or sponge roller to apply. The end result is intensified based on the volume of medium used to the ratio of acrylic paint. Dry time depends on the volume of medium used. Suitable for use on canvas, paper and wood surfaces. Available in 250ml.
