To investigate the tarnishing of a silver-gilt buckle, the nondestructive technique of x-ray diffraction was used on one of its three parts and on a replica of it in nitrocellulose. The decomposition products of the niello were removed with the replica, restoring to the gold surface its original brilliance.
