i dont know if u guys went over this or not. correct me if im wrong. this just goes into the physics of what is known as "black bodies" and the corresponding visual colors / wavelength. ill post the pic of the claw and relate that to the corresponding color. someone said it looked like glass a few pages back. well, if glass had this appearance, then it would still be the same temp as steel that looked like that. basically, black bodies look the same when heated to the same color. when someone says that is aluminum pouring out of the side of the wtc, then that alluminum still needs to be the same temp that corresponds to that color.

"The wavelength at which the radiation is strongest is given by Wien's displacement law, and the overall power emitted per unit area is given by the Stefan-Boltzmann law.
So, as temperature increases, the glow color changes from red to yellow to white to blue."
"At room temperature, black bodies emit mostly infrared light, but as the temperature increases past a few hundred degrees Celsius, black bodies start to emit visible wavelengths, from red, through orange, yellow, and white before ending up at blue, beyond which the emission includes increasing amounts of ultraviolet."
so steel starts to melt at 1370C. the temp corresponds to the top yellow color on the chart. looks to me that both pics have color resembling that.
