World Trade Center Molten Material Images
The U.S. Customs House stored a large arsenal of firearms at its Six World Trade Center office. During recovery efforts, several handguns were found at Ground Zero, including these two cylindrical gun-casing remains and a revolver embedded in concrete. Fire temperatures were so intense that concrete melted like lava around anything in it's path. (Caption From Image)
The melting point of concrete varies between 1800-2500°C (3272-4532°F) (weldcare.co.uk)
Editors Note: Concrete does not have a single melting point, it's components all have different melting points.
