I made this because I don't like waiting for a lot of items to smelt, especially when I'm out exploring.
With this mod, smelting on Furnace, Blast Furnace, Smoker, and Campfire takes only 1 game tick per item. This means Blast Furnace and Smoker are pretty much redundant since regular Furnace now smelt just as fast. And it works with all smeltable items.
⚠️ When you load the datapack, it might says "incompatible" but it will still works.
The Fabric/Forge/NeoForge mod version is also available here: https://www.curseforge.com/minecraft/mc-mods/fast-smelt
