Abstract
A metallurgical analysis of a bronze needle with a screw is presented. This analysis sheds light on the process which led to the invention of the screw. We also present one of the first examples of hardening bronze by mechanical deformation. We offer a simple method for detecting small amounts of some impurities which were present in the original metal ores, which can serve for identification of the ores.
