Sometime last year, the beard on King Tut’s famous mask came off broken off and then was quickly repaired using “a quick drying, irreversible material”. Apparently, some sort of epoxy.
Jackie Rodriguez, a tourist who witnessed the repair work on the beard in late August, provided a photo to The Associated Press showing a museum employee holding it in place as the glue sets. “The whole job did look slapstick,” she said. “It was disconcerting given the procedure occurred in front of a large crowd and seemingly without the proper tools.”
Update Sat Jan 24 11:58:55 PST 2015: German restorer, Christian Eckmann, said in a press conference today, that the mask can properly be restored.
