Hey Guys Here's a Guide on how to make an easy automation of furnace's 1. Place Down A Furnace (best to put it 1 block up off the ground) . 2. Place a Hopper on top of the Furnace . 3. Place A Chest on top of the hopper ( This is useful if you want to smelt alot of items) . 4. Place a chest in front of the Furnace then from the furnace a hopper Going into the chest . 5. If you want Charcoal or coal Going into the furnace By itself place a hopper going into the furnace on the side And if needed a chest on top. . And there you have a automated furnace. I've had a dc of cobblestone been cooked up by it, also food etc. Hope you enjoy! Remember To private the Chest, Hoppers and Furnace's!
