THE TECHNICAL PART
Bronze is an alloy of 95% copper, 4% silicon and 1% manganese with traces of other elements such as iron. Silicon bronze has been the bronze of choice for fine art castings since its development in the 1920s. It is corrosion-resistant, strong, resilient, formable and weldable. Also known as “hot-cast” bronze, a fine art “lost-wax” casting of silicon bronze is created through many labor-intensive steps.
FRP (Reinforced Polyester Resin) is an extremely viable alternative to bronze at times, as it is also suitable for outdoors and can be finished to look like many other natural materials including metal, stone, wood, and pre-cast cement. It can also receive a polychromed finish. It is extremely lightweight in comparison and can be cast and completed in shorter time-frames. FRP is also commonly used in architectural and ornamental elements, whether new or a replication.
