    • Kryptonite maintained its crystalline structure right through the intense heat of meteor impact. And yet it melts over the significantly lesser heat of a campfire? In "Hothead" they could be used as sauna rocks. (editor's note: a fire is roughly about 600-700 F - the melting point of copper is 1981.4 F, silver is about 1700 F, lead is about 621 F, just in case you were wondering... :) )
