Furnace – Smelting Recipes

A Furnace is a special block that is almost as important as a Chest. They are used to smelt certain items into resources that have different functions or attributes. Furnaces are available in all versions of Minecraft except for Classic. Before they were introduced to the game, players smelted their items by making a fire and dropping items into it. Furnaces can sometimes occur naturally in NPC villages inside blacksmith workshops.

Quick Reference

To access the smelting menu, point your cursor at the furnace and right-click it. The menu has two fields where you can place items. The field to the right of the arrow is where you can collect the items once they have been smelted. The top field is where you place the item you want to smelt and the bottom field is where you place the fuel for the furnace. The most efficient fuels are wood, wood planks, sticks, coal and buckets of lava. Other items such as fences, jukeboxes, bookshelves, chests and crafting tables can also be used as fuel, but are very inefficient. It takes 10 seconds to smelt any of the items listed below. Furnaces look quite similar to dispensers but have completely different uses. A pickaxe must be used to pick up a furnace. When a furnace is destroyed, the items left inside it are also destroyed. Once the items and fuel are placed in the furnace, the menu can be closed and the smelting will continue as long as there are still objects left to smelt and fuel available to heat the furnace. The fire icon in the menu shows how much fuel burning time is left. Another fuel will be consumed when the fire icon completely dies down. The furnace will stop using fuel when all the items in the item field have been smelted. It will also stop working if it runs out of fuel. The arrow is the smelting progress bar for the item being smelted. It will start from the beginning when it starts smelting another item or once more fuel is added. If the furnace runs out of fuel before the progress arrow reaches 100%, the input won’t be smelted and the bar will reset. Buckets are returned (not destroyed) when lava is used up by a furnace.

Smelting Recipe Guide

Smelting (Melting, Baking, Cooking, Burning, Producing) is the way you smelt or heat items in Minecraft. Through the use of a furnace (as described above), raw food can be cooked to make it restore more food points when eaten, ore can be smelted into more refined crafting materials and raw materials can be made into building materials. A furnace is used (along with some fuel) to complete all the smelting recipes below. The smelting/cooking process does not continue while sleeping.

Fuel Efficiency

Smelting an item costs 200 units of heat or “ticks” to complete. The smelting/cooking process does not continue while sleeping.

Tips and Tricks

  • Charcoal is now less useful than wooden slabs comparing to the amount of logs required, use coal from ores or wooden slabs.
  • The advantage of wood planks over regular coal is that they are renewable. As more and more coal is mined and used, you have to travel further away to get it. It takes a while to do, but farming trees and smelting wood to make charcoal is the best option because it is both near to where you are working and efficient.
  • The most efficient fuel is coal/charcoal. 8 pieces of coal/charcoal can smelt a stack of 64 items. 43 wood planks are the second most efficient way of smelting and will create 64.5 smelted resources. In order to be perfectly efficient and not lose that 0.5, place 44 wood planks in the furnace, take the first two smelted items out and refill the input field with two more non-smelted ones.
  • Furnaces can provide light if you’ve run out of torches, and they can make charcoal which can be used to make more torches which is useful when you are on a long mining expedition.
  • One bucket of lava can fuel the smelting of 100 items, but the largest stack can hold only 64 items. To maximize the efficiency of using lava, place a bucket of lava in a furnace along with a stack of 64 items. Come back between 6 minutes and 10 minutes and 40 seconds later. Remove the 32 smelted items and refill it with 32 more non-smelted blocks.
  • For large products that require large numbers of smelted items, a wall of furnaces can be built. Coal or charcoal should be used when smelting items at this scale.
  • The Furnace is part of the “Hot Topic” achievement and is needed for the “Acquire Hardware” and “Delicious Fish” achievements (you need to smelt iron and cook fish to complete them).
