My vases are created by a layering technique similar to Japanese Urushi. Chinese call it lacquer carving, but without color.
I use a granulation method in many of my jewelry designs that call for fusing of precious mestals. This retains the crisp detail and imagery in tact rather than attachment using solders.
My patinated copper and brass cuffs are water proof, completely sealed from any moisture: Salt water, hot-tubing or showering..
