CRAFTBOOK-2720 - Reported by Богдан.Шкляренко

Put item into furnace and got 3 iron ingots for 1 iron pick
Or 1 iron ingot for 1 broken pick

And it for all items. 1 more... If we put chest->hopper->furnace->hopper->chest - we can put any items in upper chest and got back resources on bottom chest

Hmm, I'm not sure if this fits the use case of craftbook

Can't this already be done with custom crafting?
