Bronze & Pearlescent Powders
Bronze powders are a mixture of copper and zinc with the ratios changing to give different shades of “gold”.
The powders can be mixed with a suitable medium (such as Ormoline bronzing medium) to make a metallic paint or can be dusted onto (for example) an oil based gold size.
The powders will tarnish if exposed to the air so the finish should be covered with a suitable varnish such as Roberson’s Universal Lacquer to protect them.Mica powder in a range of shades is also available to achieve attractive pearlescent effects. These can be mixed with almost any medium without tarnishing or reacting in any way.
