The hearth that overwhelms this room is made from pure wrought iron and
glows red from the extreme heat of the fire inside.  Coal is dropped in from
a conveyor belt that is to the left of the hearth, keeping it well fueled
for the extreme temperatures that are needed for smelting the ore.  You
begin to perspire as waves of heat pour out from the hearth.  Perhaps you
should move on.
