Stunning Patinated Copper Jewelry Collections
San Francisco jewelry designer John S. Brana introduces his new patinated handmade copper jewelry collection Muir Woods that premiers at Bloomingdale’s – Stanford, October 3rd & 4th from noon to 5 p.m. – Palo Alto, CA.
Patination, or chemical coloring is an art that encompasses both craftsmanship and experience. Coloring strategies of copper depend upon time, temperature level, area preparation, moisture and various other variables. Pre-patinated copper sheets are generated by makers under controlled environments utilizing patented chemical procedures. Environment-friendly patina finishes are mainly developed using acid chloride or acid sulfate. Treatment solutions with ammonium chloride (sal ammoniac), cuprous chloride/hydrochloric acid, and ammonium sulfate are somewhat successful.
As in the jewelry featured in the above video, surfaces can be produced in light, medium, and dark brown shades, along with greens and blues, relying primarily on number of tinting applications and chemicals used.
