Crucible

A crucible can be used to melt cobblestone into lava. You can craft a crucible by dropping an unfired crucible into a fire. Crafting your first crucible earns the player the advancement "You're Fired".

How to use a crucible:
 * 1) Place it above a heat source, such as a torch, lava, or fire
 * 2) Drop 4 cobblestone into the crucible to fill it, then the cobblestone should melt into lava
 * 3) Drop a bucket into the crucible to remove the lava from the crucible and fill the bucket2017-06-04 08.24.37.png
