Fragment with working traces
New Kingdom, Amarna Period
This amorphous fragment from the statuary dump outside the Great Aten Temple has two hammered faces, one of which is considerably smoothed. It also has what appear to be the remains of drill channels. One drilled partly open channel holds in its lower end the remains of a bronze tubular drill and the corundum-containing abrasive used with it.
