Pearl Excreates 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 looks — from 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 stable — it will not tarnish or fade and is therefore ideal for archival applications.
But the most exciting thing about Pearl Ex, besides its beauty, is its incredible flexibility. It can be mixed into any viscous medium and applied to any surface. Mix it into oil, acrylic, gouache, varnish, clay, melted wax and so on. It can also be spread dry on porous surfaces. Use it on clay, glass, metal, wood, paper, fabric, just about anything.
Note: you must buy Gum Arabic to mix with the PearlEx which canbe used with the Shimmering Resist tech in the Aug/Sept Tech Junkies issue. ISC does not carry Perfect Pearls and Pat said this can be a subsitute.
