The tomb remains unexcavated due to concerns over potential destruction, lethal booby traps, and dangerous levels of mercury that may be present in the environment.

What evidence supports the possibility that rivers of mercury exist in Qin Shi Huang's tomb?

Soil analyses and atmospheric studies near the tomb have shown significantly elevated levels of mercury, supporting the possibility that large amounts of mercury might be present in the tomb.

How did ancient civilizations extract mercury from cinnabar?

Ancient civilizations used both cold and hot extraction techniques. One cold method involved grinding cinnabar with copper and vinegar to produce liquid mercury, while hot extraction methods included heating cinnabar with iron or sodium carbonate.

What discovery did researchers from the University of Bologna make about ancient mercury extraction methods?

Researchers successfully recreated ancient mercury extraction methods described by alchemists, confirming that grinding cinnabar with copper and vinegar or heating it with iron or sodium carbonate could produce liquid mercury.

Why was working in cinnabar mines considered a death sentence in ancient Rome?

Cinnabar is toxic due to its mercury content, and exposure to mercury vapor was highly dangerous. Slaves and criminals forced to work in cinnabar mines faced almost certain death from mercury poisoning.
