Show crucible fuel type on recipes

There should be some indication of what kind fuel you need in the crucible for a given recipe.
Too many times have I put sticks in the crucible only to be told that I need coal and now I have to wait for it to burn down.

I think letting us clean out the fuel would be more useful. Even with an indicator people will probably still mess up.

Also if you try adding coal into a crucible already burning wood, you just made it burn wood even longer!

That would be nice. I was kinda sad the first time I put lava into one and it told me "Nah, you need coal" and I had to wait out the burn.
