The Fleur de Lys Door Knocker is sand-cast in solid brass and finished with a high polish. 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 Fleur de Lys Door Knocker was designed by Michael Healy, an accomplished Rhode Island artisan known for his truly unique Door Knockers. Contrary to popular belief, the Fleur de Lys did not originate in France, but rather was first popularized in ancient Rome. Michael, an avid history buff, was inspired to create this Fleur de Lys Door Knocker in the spirit of its original significance. The Fleur de Lys (derived from the Celtic word "li" or "lly" meaning king or ruler) is a symbol of power, life and purity and was first coined as the "flower of kings." What a uniquely elegant way to greet visitors.
