Mnemonic

A block of ice sits on a pedestal in the center of a blazing forge. The intense heat transforms it—first to water, then to steam—demonstrating the raw power needed for smelting. If ice can vanish on that pedestal, imagine what happens to raw ore!
Additional thoughts
Ice on a pedestal inside a forge: the contradiction of cold meeting extreme heat is the essence of smelting. The pedestal is where the crucible sits, and ice reminds you that even the coldest substance yields to the furnace.
Quick recall
Ice on a pedestal in a roaring forge melts away, proving the overwhelming power of smelting.
