There’s a moment in this video after the molten copper is poured on top of the raw steak and after there’s been a little time for the copper to cool down and after the steak has cooked a little bit that it looks like the metal has completely engulfed the steak and casted a metal sculpture of meat. Since the steak is on a pan and the molten copper gets to pool a bit, you can see the red of the steak turn brown and gray pretty quickly.
