Herculaneum Vesuvius volcano eruption 79 AD vitrified glassy brain Fulgurite archaeologist slag

"archaeologists " Petrone et al said fragments of vitrified glassy material containing traces of fatty acids common to the triglycerides in the human brain, along with human hair components were extracted from ONE cranial cavity of a victim first excavated in the 1960s from Herculaneum where their should have been only glycerol and fatty acids , so we hear of the Vesuvius volcano eruption in A.D. 79 that baked some people to death & turned one brain to glass , " if these tales of biological transmogrification are verified by future research"
or
just "baked" by lower-intensity heat

Fulgurite = electricaly sintered, vitrified, and/or fused soil, sand, rock, organic debris
and other sediments that sometimes form when lightning discharges into ground.
as tubes, clumps, or masses

1,548°F is the melting point of calcium a reactive metal that forms a dark oxide-nitride layer when exposed to air.

Metal workers use fluxes in smelting for several purposes, chief among them catalyzing the desired reactions and chemically binding to unwanted impurities or reaction products. Calcium oxide, in the form of lime, was often used for this purpose, since it could react with the carbon dioxide and sulfur dioxide produced during roasting and smelting to keep them out of the working environment

I brought up the possibility that volcanic lightning possibly hit this person and
turned the brain into a fulgurite (and also note what happened with the bones)
with one of the scientists named Elzbieta Jaskulska and not sure is this is her
answering from another facebook but worth following. I also ordered the ..
