The Indus Valley Civilization, flourishing around 2500 BCE, utilized the lost wax method for metal casting. This technique involved creating a wax model, encasing it in clay, and then melting the wax to leave a mold for metal.

Artifacts like the famous ‘Dancing Girl’ statuette exemplify their skill. Although the method is understood today, the sophistication and scale at which it was employed by this ancient civilization remain impressive.

Flexible Glass of Ancient Rome: Myth or Misplaced Invention?
