Pearl Ex Powdered Pigments are an extremely versatile product! They can be mixed into any media and applied to any surface! And the variety of finishes Pearl Ex can produce is nearly endlessβfrom metallic sheens to pearlescent shimmers to all manner of faux finishes. Pearl Ex creates a metallic look without being a metal. The particles are flat platelets with two surfaces, therefore it lays down beautifully like a thin coating of metal. The different particle sizes produce different looksβfrom a fine, smooth, pearly luster to a highly metallic sheen. It is a safe, non-toxic, inert powdered pigment with a neutral pH. It is extremely color fast and stableβit will not tarnish or fade and is therefore ideal for archival applications.
