The Lighthouse Door Knocker is sand-cast in solid Brass with Bronze highlights. Brass and bronze are copper-based alloys. The yellow brass alloy used in many of Michael's designs contains 70% copper and produces a warm, traditional brass look. Red bronze contains almost 85% copper. This additional copper content gives the bronze alloy its rich, reddish undertone. The mirrored finish of polished brass and polished bronze is achieved through varying degrees of sanding and buffing. Michael uses these techniques to highlight or accent the raised areas on a piece.The Lighthouse Door Knocker was designed by Michael Healy, an accomplished Rhode Island artisan known for his Unique Door Knockers. Lighthouses spark feelings of security and nostalgia for Michael, who grew up on the shores of Cape Cod. These midnight beacons have been used for thousands of years to guide people to safety. A symbol of both warmth and home, the Lighthouse Door Knocker is a welcome sign on any door.
