The forbidden furnace datapack adds an feature where you can smelt
a mace, blaze rod, diamonds, etc. I'll be testing this datapack for
3 days to check for any bugs, things that aren't working, etc.
► Smelting Ingredients.
- smelt stick = mace.
- smelt dirt = diamonds.
- smelt copper ingot = netherite ingot.
- smelt gunpowder = blaze rod.
- smelt coal = eyes of ender.
