Mr Denys Stocks, an old policeman, has just been given a prize for 12 years' research into ancient Egyptian industrial methods. People often wondered how the Egyptians were able to cut such hard stone and how they produced such fine jewellery. Mr Stocks has shown that the Egyptians used saws (锯) and drills (钻). The saws and drills were made of copper (铜), which is very soft. But the Egyptains turned them into very powerful tools. First, an Egyptian made a cut in the stone with a soft saw. Then the Egyptian put some sand into the cut. The hard sand got into the teeth of the saw and did the cutting. In this way, a worker could cut one of the hardest rocks. The sand he used turned into a very fine powder. The powder was then used by jewellers to cut valuable stones to make good jewellery.
