Did you know there is a massive iron pillar in the heart of Delhi that has stood exposed to the sun and rain for over 1,600 years without a single speck of rust? 🤯
Iron naturally degrades when it comes into contact with air and moisture. While Western iron from the exact same era crumbled into dust long ago, this Gupta-era masterpiece remained perfectly intact. For centuries, Western scientists were completely baffled by it.
The secret lies in an ancient Indian mastery of “corrosion science”. The ancient smiths used a technique called forge welding and deliberately maintained high phosphorus levels to create a secret “passivation” layer on the metal’s surface. This layer acts as an invisible shield, preventing the iron from rusting. This ancient knowledge is the same foundation of corrosion science that protects our modern bridges and pipelines today!
Dive deeper into the untold history of ancient Indian metallurgy! This video is based on the book Zero to Gravity: The Ancient Indian Roots of Modern Science by Sri Narasimha Patrudu. Visuals synthetically reconstructed using AI to bring ancient indian science to life. Research based on my book Zero To Gravity.
