These striking products are made using molten Bronze flowing into cavities within a sand mould.  This casting process leaves light surface indentations to bestow a rustic appearance.   A light patina coating is applied by hand on the cast bronze. creating a country-style appearance. Over time the bronze colour will lighten on surfaces which are regularly touched creating a naturally aged appearance. When left untouched the finish may darken as the bronze oxidizes. As this is a living finish the products will not be identical. There will be a slight variation in hue and tone. These mortice knobs are un sprung and will need to be installed with a  3 inch heavy duty latch.
