Not really bright orange like what was seen running out of the towers. It looks grayish and silvery to me even in that photo. Professor muttonhead says silver to gray in color too. That's been my experience when casting with aluminum. It pours out silvery in color.

Molten aluminum, while still in the presence of its heat source, is red.
HOWEVER, the point that has been made, which you did not at all address, is that AWAY from the heat source, and pouring...molten aluminum is silvery gray.

Did you deliberately ignore that the point is the color away from the heat source while pouring? Or were you just not paying attention?

Don, there's two things that could be causing that orange color. First the dross on the top of molten aluminum can be orange-ish, and the molten aluminum being silver can reflect the color of lights and red hot crucibles.
