Heat Block

Heat block is a block that can melt snow and ice just like a torch except it does not give off light.

Usage
Heat blocks melt snow layers and ice within 2 blocks (taxicab distance). It is unique in that it is the only block that melts objects without giving off light.

Trivia

 * Iron corrodes in salt water way faster than it does in water, because electrochemistry is involved.
 * The ingredients of the heat block corresponds to the contents of hand warmers. A hand warmer generates heat due to the same electrochemistry that rusts iron in seawater, but with powdered iron the effect becomes more appreciable.
