Workers used a technique involving dolerite balls, which are small, hard stones that are more durable than granite. These dolerite balls were likely used to chip away at the granite’s surface slowly, leaving characteristic marks that are still visible on the rock. The painstaking process of chiseling the rock away required both skill and endurance, as workers carved along the desired shape of the obelisk using repeated, controlled strikes.
The Egyptians also employed ingenious methods to separate the obelisk from the bedrock. After carving it almost entirely out of the granite bed, workers would create small cavities along the line where they wanted the rock to split. They filled these cavities with dry wooden wedges, which were then soaked with water. The wood would expand as it absorbed the water, generating enough pressure to fracture the rock along the line of the cavities. This natural technique allowed the stone to detach cleanly from its base, a testament to the Egyptians’ resourcefulness and understanding of materials.
