Replication of an Anglo-Saxon brooch
Conservation Technologies made a replica of an Anglo-Saxon great square-headed brooch (approximately 160 mm x 90 mm) for visitors to examine and handle at the Weston Discovery Centre|, World Museum. The surface of the gilded bronze brooch was too fragile to mould and so a non-contact approach| was used. The object was laser scanned| and a master pattern produced from the resulting computer model using a 3D printing process. A replica was then cast from the master pattern in a copper alloy. The replica brooch was gilded and finished by hand and a new clasp fitted to its back.
