The Sunface Door Knocker is cast in Solid Brass. 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 Sun Face Door Knocker was designed by Michael Healy, an accomplished Rhode Island artisan. While traveling in Europe, Michael was impressed by the rich variety of sculpted architectural detail. One such detail he encountered in the Alps was the Sun Face. Michael made a sketch of this happy image which years later became the subject for one of his unique Door Knockers.
