The Fuel

This mod is a simple mod that adds a few items that burn without over or under burning when smelting.
There are 7 items to add.

The first two are Small coal and Small charcoal that burn for 10 seconds.

The next three are Efficient fuel, Super efficient fuel, and Extremity efficient fuel, which burn for 10 seconds and consume a durability value.
Each of these has a durability value of 10, 100, or 1000.

The last two are Eternal Love, the highest fuel item in the mod, and Love Eternal, a weapon created with Eternal Love that can also be used as fuel.
These have a durability value of 10,000 and will not break even if used as fuel.

Eternal Love and Love Eternal can be smelted to reheat love and make it as hot as when you first met.

Tips: The Love Eternal will deplete its durability quickly and break when attacking mobs.

Sorry for my bad English.

Have fun!
