How did Ctesibius of Alexandria achieve the necessary elasticity in the bronze alloy used for crafting springs?
Answer
By hammering the bronze alloy after it was cast
Ctesibius of Alexandria devised a specific method for working with bronze alloys intended for spring creation during the early metalworking periods. The key step involved physically manipulating the material subsequent to its casting. By hammering the bronze alloy post-casting, he managed to induce the required elastic properties into the metal, demonstrating an early, sophisticated understanding of shaping materials to harness resilience, even without the later coiled form.
