Pigment in Resin, this technique is not reproducible.  The effect is difficult to obtain when considering the liquid nature of the resin and the dry time.  Having these mixed colors controlled in any way is a long shot and wishful thinking, but this one came out.  Of many attempts, as messy as the process has been, this one finally did come out.  This one of a kind beauty has metallic and other pigments throughout which sparkle ever so gracefully across the entire huge 2 foot of surface.  This is an inspired piece by a full time artist that normally works with oils.
