Ancient Egyptian stone artifacts display striking drill and saw marks—cone-shaped cores, concentric striations, and parallel cuts—demonstrating precision drilling and sawing techniques using tubular copper tools and abrasive minerals. The granite core published by Petrie was made by ancient Egyptians using a tubular drill, with each concentric line representing a single rotation of the drill. Long saw cuts through stone and vertical parallel saw marks next to each other are also documented in Egyptian stonework.
Tool Mark Similarities: Chinese Jade vs Egyptian Stone
Key facts
- Tubular drill marks on ancient Chinese jade resemble markings on Predynastic and Dynastic Egyptian stone vases and granite cores
- Liangzhu jade cores show concentric striations similar to Egyptian granite cores
- Both Chinese and Egyptian cores are cone-shaped, narrower at the bottom due to drilling dynamics
- The spiral concentric lines were caused by hard abrasive mineral grains during continuous rotational drilling
- Straight rigid saw marks on Chinese jade fragments resemble saw marks on ancient Egyptian stone items
- Both have straight parallel shallow marks
- Chinese used bamboo tube drills while Egyptians may have used copper tubes
