To start adding furnace fuels via JSON files, first of all you have to make a data pack, and create a few file folders. You path should look like this data/your_mod_id/jinxedlib/furnace_fuels
Then you create a JSON file in the compostables folder, this can be named anything but I recommend naming it something sensible.
My JSON file named 'fuels' looks like this:{
"values": {
"minecraft:copper_ingot": 120
}
}
Values takes in an item and an integer, the integer is the burn duration.
