The Sunface Door Knocker is cast in Solid Brass- Brass and bronze are copperbased alloys- The yellow brass alloy used in many of Michaels 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-Specifications- Material Brass- Mounting screw center to center distance 2 58- Dimensions 6-5 H x 2 W x 6-5 L SKU: MCHD049
