Glass

A smidgen of clarification: news stories said a Vesuvius victim's brain turned to glass. Make that a glassy substance: there's no silica in it like window glass. Glass is a very generic term for solids that seem uniform but have no obvious crystal structure. (Sometimes there's microscopic crystal structure.) This one seems to be scorched proteins and fats, and maybe some other stuff that didn't show up in the report.
