  1. A young man’s brain turned to glass during the eruption of Mount Vesuvius. Scientists say they have figured out how

    However, the pyroclastic flows, composed of fast-moving volcanic material and toxic gas, that charged out of Vesuvius and buried Herculaneum could not have caused the brain tissues of this young man to turn into glass, he said.

  4. Study: Hot Vesuvian ash cloud really did turn a brain to glass

    The results: "Our comprehensive chemical and physical characterization of the material sampled from the skull of a human body buried at Herculaneum... shows compelling evidence that these are human brain remains, composed of organic glass formed at high temperatures, a process of preservation never previously documented for human or animal tissue, neither brain or any other kind."

Summary

A summary of the key points of this story verified across multiple sources.

Research on a Vesuvius eruption victim indicates their brain was preserved as glass after exposure to superheated ash and rapid cooling. This unique phenomenon occurred at temperatures exceeding 510°C and is the only known case of human tissue naturally vitrifying. The study authored by Guido Giordano suggests that the specific conditions during the eruption led to this rare preservation, detailing the sequence of events that took place in Herculaneum during the catastrophic eruption. The findings serve to advance our understanding of volcanic impacts on human remains and raise questions about other potential vitrified remains.


Perspectives

Compare opinions on this story from liberal (Left), conservative (Right) or center-leaning news organizations.
  • The recent study provides compelling evidence that the cloud of ash from the Mount Vesuvius eruption in 79 AD generated extreme temperatures that caused the young man's brain and spinal cord tissue to vitrify into glass, thus preserving it in a unique manner.

  • While there is skepticism within the scientific community regarding the process of vitrification of human tissue, advancements in forensic techniques have been employed to support the claim that the material found is indeed organic glass formed at high temperatures.

  • This discovery illustrates the rare but fascinating forms of preservation of human remains, contributing to the knowledge of archaeological and volcanological events.
