Woolley employed an ingenious technique to lift fragile artifacts, like these skulls, out of the ground. He would pour molten wax over them and then overlay strips of waxed fabric to stabilize the objects. Once these had hardened, he would lift the object and its surrounding soil as a block and move it to a workroom where it could be carefully exposed. As a result, we have an excellent record of the objects he recovered from the Royal Cemetery.
