Re: Molten Metal
Its not temperature that burns you, its heat transfer
if you put a pizza in a 400° oven it doesnt not instantly reach 400°, it takes about 20 minutes to heat-soak (cook)
likewise, if your skin makes contact with molten metal, it would take time for the heat to transfer, and cook your skin
It does not say in the video what metal that is - the lower the density of the metal, the less heat it would contain, so maybe its aluminum?
but the bottom line is, how long is his skin in contact with the metal? 1mS? 10µS? If his hands are calloused they would be poor heat conductors, and it would take longer for his hand to be burned.
BTW, the reason you can walk on burining coals is, they are mostly carbon by the time they are coals, and they conduct heat very poorly - again, its not a question of temperature, its a matter of heat transfer.
