The furnace separator will save you the hassle of preparing the furnaces.

Simply place the ore in the furnace and it will be divided into a configurable number of piles.

The specified number of stacks is saved for each player and the type of furnace they use.

This means that you can divide the stacks into 3 in small ovens and 15 in large ovens

without having to switch between them every time you use a different oven.

The main thing is that when you put something down for melting, the plugin automatically adds

the right amount of firewood from the inventory.
