The Column that Dr. Jones said could not be cut with a torch, the steel of the column was actually the fuel to do the cutting with a torch, where as thermite uses aluminum to give heat to iron and then that Iron heats the Column though contact.
The hottest temperature ever attained by a thermite device on steel is significantly lower than that obtained by a torch or an Oxygen lance, because the main cutting source of an oxygen lance is oxygen actually burning though the material to be cut, using it as fuel to do the cutting.
The best way to design a thermite device for cutting is design one that creates a gas flow that is oxygen rich and would use the material Iron as the fuel to cut though the column.
Sulfur will not do that it will only lower the melting temperature, super heated water in the vapor phase will, and it will cool the device where the thermite will not destroy the device before the cut is made.
Do not tell anyone though I do not want anyone knowing how I did it in the twin towers, I promised GWB. a perfect JOB. No traces and no evidence.
