When working with solid rocks, ancient Egyptian artists and artisans used stone tools, including the number of silicon, and copper. Since the era of the New Kingdom (around 1550 BC) they began to make bronze instruments, and later – iron. The stones were processed using copper drills and saws as well as abrasives (e.g. silica sand) in huge quantities. During the extraction of granite in quarries of Aswan and its processing to create ancient building blocks, obelisks and sarcophagi stonecutters used dolerite balls (dolerite – natural igneous stone rocks, the main component of which is basalt).
