WTC steel with diagonal cut, thermate residue. Based on chemical analysis of WTC structural steel residue, a Brigham Young University physics professor has identified the material as Thermate. Thermate is the controlled demolition explosive thermite plus sulfur. Sulfur causes the thermite to burn hotter, cutting steel quickly and leaving trails of yellow colored residue (See picture, below, of streaming molten metal)
