I imagine a simple DataPack use.
If you know how to use an oven you know how to use this datapack, This the same interface as vanilla ovens.

This DataPack adds 4 furnaces in Iron, Gold, Diamnt, and Extreme.

IronFurnace ---> Cooked twice as fast as a normal oven
GoldenFurnace ---> Cooked 4 times faster than normal oven
DiamondFurnace --->Cooked 8 times faster than normal oven
ExtremeFurnca --->Cooked 20 times faster than normal oven

Fuel can cook more item, I will take a stick for example :

Vanilla ---> 2 Stick Cook 1 Item
IronFurnace ---> 2 Stick Cook 2 Item
GoldenFurnace ---> 2 Stick Cook 4 Item
DiamondFurnace ---> 2 Stick Cook 12 Item
ExtremeFurnca ---> 2 Stick Cook 40 Item
