Iridescent paint is a thin transparent coating, usually on glass, plastic, or metal, that produces brilliant reflecting and diffusing effects in changing light. It is similar to glaze on pottery but much thinner. It may be applied to the surface of a material, or sprayed onto glass and then fired in a kiln.
Iridescence is caused by interference, which is dependent on the thickness of the coat. Thin coatings (one-sixth of a wavelength) produce iridescence; thick coatings (one-fifth wavelength or more) produce other optical effects such as structural color and nonlinear optics.
How Does iridescent Paint work?
Iridescent paint is supposed to have the shimmer, while it also has a deep color that gives the surface depth and the shimmer look.
It is a paint that is mixed with metallic flakes and provides a shimmering effect. It will provide the glimmer look while accenting the color of the paint.
An iridescent medium gives a smooth iridescent appearance that will make the paint “pop”
It extends the color life of the paint. It will also slow drying times to blend color better. It also maintains paint adhesion and durability.
