The Scallop Shell Door Knocker was designed by Michael Healy, an accomplished Rhode Island artisan. The Solid Nickel Silver Sea Scallop is cast in 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. Michael grew up on Cape Cod and has happy memories of his youth spent combing the shoreline. A shell as large and pristine as your Scallop Door Knocker would have been quite a find.
