Welding metal you can get very localized 3 degree burn outside picking up a large hot piece.
“5 seconds at 140 deg contact with the skin can cause 3rd deg burns.”
3rd degree burns involve charring of the skin and a smell like BBQ. Unless the liquid is a 400F metal one has to continue to heat the substance (or it be ectothermic) for anything but a superficial burn.

Not necessarily.
Had a passed out friend who’s leg
was severerly burned (required skin
grafts to repair), after exposure
to a heater vent all night.
Badly burned, but not blackened,
and it didn’t smell.
3rd deg burns are damage done to a
depth of muscle tissue.
