The purpose of this tutorial is to teach how to smelt items automatically, without having to put them in and get them out manually. You will need hoppers, furnaces, and 3 chests. Additionally, furnace can be replaced with smoker for faster food cooker or blast furnace for faster melting ore or nuggets
This semi-automatic design uses hoppers, and is not too difficult to build and is inexpensive.
See below for a step-by-step guide on how to make this semi-automatic furnace design. Sneak (hold down ⇧ Shift) to attach blocks to each block that has an inventory, such as attaching a hopper to a chest.
- Step 1: Place down a chest on the ground. (This will be the chest in which the smelted/cooked items will be put)
- Step 2: Attach a hopper to the chest (side or top is fine).
- Step 3: Place the furnace on top of the hopper.
- Step 4: Place one hopper on the top and 1 hopper on the side (left, right, front, or back) of the furnace. (The top one will insert the items into the furnace, which get smelted / cooked; The hopper on any side-face inputs burnable fuels into the furnace)
- Step 5: Place a chest on top of each hopper attached to the furnace.
Variations: You may choose to add switches to control the hoppers. Switching off the bottom hopper stops it from taking items out, allowing you to collect the experience from smelting them. Switching off the top hopper allows you to fill the top chest with various items, then eventually smelt them all in one go, reducing the fuel waste normally incurred by smelting partial stacks. The fuel hopper on the side never needs to be switched off.
Multiplayer: On servers that have chest and furnace protections, you may have to unlock these before the hoppers are able to interact with them.
Making two furnaces increases the rate of production much faster. Have a chest on top for the item to be smelted, and at the back, put a fuel chest.

Automatic Item Sorting Furnace
Compact Item Sorting Furnace: Minecraft Redstone Tutorial Video
This fully-automatic build allows for seamless integration into an existing item sorting system, and runs automatically in the background as a predetermined item is collected before reaching its final storage location.
Items collected by the item filter will be smelted by an internal furnace, collected by a set of hoppers, and transported back to the main hopper line with a dropper item elevator to be transported to a chest or storage system. This design will require the occasional addition of coal or fuel, when its corresponding chest runs low, to keep the furnace running.
The following items can be smelted with this automatic furnace design:
Tiny Fuel Generator
This design lets a furnace producing charcoal feed its product back into the furnace to fuel itself. It needs to be started off with one piece of charcoal (or for that matter, any fuel) in the chest. If more than 5-6 stacks of wood are available, another chest for input can be placed atop the upper hopper. Note that this design uses a comparator, which requires access to nether quartz.
The chest will not start receiving charcoal until both the furnace and the hopper feeding it fuel (level 2) are full. However, the hopper can be "stuffed" with four non-fuel items in its last four slots, as long as you leave the first slot open for fuel. Then the chest will start getting charcoal after two stacks of charcoal are produced, which will require 2-1⁄4 stacks of wood.
See the following video for an example of how to make this:
