Coal 2 Charcoal
For the ones who don't know. Put coal in the crafting table and get charcoal, and same goes for charcoal.
Coal 2 Charcoal allows you to convert coal into charcoal, and the other way around...
This is my first mod and it is a very simple idea, I was surprised someone hadn't already made it, The Idea was by me and some input by community members.
