Wootz Steel

Alloys · Rare · Ancient

The source material for Damascus steel, wootz is a crucible steel developed in South India and Sri Lanka dating back to at least 300 BC. Its unique carbon nanotube-reinforced microstructure, discovered by modern metallurgists, explains its legendary properties.

Lore & Narrative

Modern analysis revealed that wootz steel contains carbon nanotubes and cementite nanowires, structures that scientists could not synthesize until the late 20th century. Ancient Indian smiths were inadvertently creating nano-engineered steel over two thousand years ago.
