[TheForge] FW: [The_Anvil] Dont put your tongue on a frozen anvil

[Chris Kilpatrick]

The metallurgy of the hull takes into account the temperature range.  That is a whole subset of metallurgical study.  Probably less carbon and special alloys to make it the right strength at the right temp.

It is I who formed the blacksmith, 
who fans the flame into a fire and
fashions a weapon fit for it's work.
