The nickel silver whaletail is cast in Solid nickel silver. Nickel Silver is an alloy that has a warm silver color which is attained by adding nickel to bronze. Michael combines a high polished finish with brushed accents to generate a contemporary look. A stainless steel brush on a high speed lathe is used to create the brushed effects. The mirrored finish of polished nickel silver is achieved through varying degrees of sanding and buffing. Michael uses these techniques to highlight or accent the raised areas on a piece. Each Doorknocker is hand polished and then the knocker is then coated with a clear lacquer to protect the original polished finish. Michael Healy has signed this Lobster Doorknocker in the mold, confirming its authenticity and quality craftsmanship.
