Antique Nickel (Pewter) Door Knocker Selection
Sometimes called "Pewter" the surface of the casting's natural brass gold tone is machine buffed smooth and hand polished. An abrasive media is used to dull the surface and create a horizontal grain to the surface. The casting is then engraved. Following the engraving the casting is nickel plated to create the silver finish over the satin brass. The casting is then placed in an oxidizer bath to turn the surface almost black. The black oxidation is polished leaving a darkened satin finish with darkened highlights.
