Talk:Refined Iron Dust/@comment-173.51.68.102-20121112204416

I would like to point out that refined iron dust can be made with charcoal as well. :D

Here is my math:

1 charcoal (to macerate 2 stacks of refined iron dust) + 16 charcoal (to smelt 2 stacks of refined iron) = 17 charcoal per two stacks of refined iron.

0 charcoal (to macerate two stacks of iron dust) + 16 charcoal (to smelt 2 stacks of iron bars) + 16 charcoal (to smelt 2 stacks of refined iron) = 32 charcoal per two stacks of refined iron.

17 charcoal < 32 charcoal. It is more efficient to make refined iron dust than to smelt it twice.
