Conservation technologies
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 Liverpool. 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.
