Molten Aluminum is not bright yellow. It´s silvery. That E. Jones demonstrated it on his pappers and videos. Has it been debunked? Where? (the specific issue on the color of molten aluminum). Serious indications that the case is for molten steel.
I don't know who "E. Jones" is.
The problem with trying to identify materials through color is that it is dependent on several factors. The temperature of the material determines the black body radiation, but this is not the only form of radiation from a surface. You also have the possibility of transmission (radiation that travels through non-opaque materials) and almost certainly reflection. More importantly, your "data collector" needs to be calibrated, which I'm guessing wasn't done for the cameras filming the event. If you're trying to determine temperature and composition of a material from visible spectrum collected with a non-calibrated device, you're going to have difficulty convincing anyone knowledgeable of your conclusion.
