Denys Stocks is an archaeologist at the University of Manchester who conducted experimental replication of ancient Egyptian stone-working techniques, demonstrating that copper tubular drills with sand abrasives can produce precise vessels from hard stones. His peer-reviewed book published by Routledge and hands-on experimental validation of ancient techniques provide solid evidence that conventional explanations adequately account for Egyptian stone work without requiring advanced or unexplained technologies.
