New evidence has emerged that provides a smoking gun for the ancient practice of granite machining on Elephantine Island. Elephantine Island is an archaeological site located in southern Egypt that has long been associated with granite quarrying and carving activities. This new discovery supports the theory that advanced stonecutting techniques were used by ancient Egyptians to shape granite.
The evidence was found in the form of "waste" granite fragments, or slurry, that had been left behind by ancient stonecutters. The slurry was found in a rock-cut basin near the quarry, which suggests that it was used as a site for granite processing. This basin contains traces of quartz and feldspar, which are common minerals found in granite.
