The photos shows an initial attempt at casting a Bronze Quatrefoil, still hot from pouring. Cast using a sand mould, each segment of the sand mould was made individually and assembled to create the final mould. It’s a complicated process which resulted in a sand mould made up of 25 parts!
This challenging project of replicating the old Quatrefoil pattern on a large scale is an interesting case of using modern manufacturing techniques such as CNC machining together with traditional and ancient processes such a bronze casting. Fun Fact: At full scale when each Quarterfoil is cast, each piece will weigh 32kg. The final project required more than 50 pieces, that’s almost 2 tons of bronze and they pieces will eventually to be mounted on the side of a listed building!
