Unearth the mysteries of the Terracotta Army, where over 8,000 soldiers guard the tomb of China’s first Emperor.
Discovered in 1974, these clay warriors hold a secret — their weapons are coated with chromium.
Chromium plating involves coating objects with a thin layer of chromium, significantly enhancing durability and preventing rust. Not rediscovered until the late 20th century, this technique marks the Terracotta Army as a technological marvel of ancient chemistry. Or does it?
New findings suggest a different view. Instead being a metal treatment, traces of chromium found were linked to the lacquer used on weapon handles. Not all experts agree though, keeping the door open for further discoveries.
