What is a blast furnace in Minecraft

Melting furnace

This article covers the furnace. For the normal oven, see oven.

The Melting furnace is a block for melting objects, similar to the furnace. It can also be used for an automatic oven.

Properties [edit]

  • It can only melt ores, tools, weapons and armor made of iron or gold, but processes them twice as fast as a normal furnace. He can also melt ancient scrap into netherite plates.
  • Coal and other fuels are also used twice as fast, which saves time, not fuel.
  • The melting furnace can only be moved in the Bedrock Edition.

Extraction [edit]

Melting furnaces can be picked up with any pickaxe. However, if they are destroyed without a pickaxe, nothing will be dropped.

Occurrence [edit]

Melting furnaces are found in the houses of armaments smiths in villages.

Manufacture [edit]

Use [edit]

Melting furnaces are used to melt ore blocks twice as fast as a normal furnace, which is half the experience. When a melting item and fuel are placed in the melting furnace, the block state changes to and the item melts. The finished product can then be collected. As with normal furnaces, a funnel can be placed on top of a melting furnace and also pick up items from it.

Info [edit]

Melting furnaces cannot be moved by a piston in the Java Edition.


A furnace can be dismantled by any pickaxe. If it is mined without a pickaxe, it will not drop anything.


Melting furnaces are similar to furnaces, but can only melt ores, blocks, and tools / armor made from iron, gold, or chain mail. Once an item and fuel are put into the blast furnace, the block state changes and the item is melted twice as fast as a normal furnace. Fuel is also used twice as often as regular stoves, so the number of items melted per fuel stays the same. As with normal furnaces, a funnel can be fed into a melting furnace and also receive items from it.

Light source [edit]

Melting furnaces emit a light level of 13 when active, just like normal furnaces.

Explosion resistance [edit]

Melting furnaces have an explosion resistance of 3.5, the same as the normal furnace.

Custom name [edit]

By default, the GUI of a melting furnace is marked with "Melting furnace". However, this name can be customized by naming it before placing it in an anvil, or by changing the tag using the / data command.

Change occupation [edit]

If a village has a smelting furnace that has not been claimed by a villager, any nearby villager who has not selected a block has the option to change their occupation to an armorsmith.

Block state [edit]


The direction the front of the block is facing. The direction is opposite to the gaze of the player when placing the block.

NBT data [edit]

  • Oven, Melting furnace and smoker have the block object IDs "furnace", "blast_furnace" and "smoker"
    • General block object properties
    • General container properties
    • BurnTime: Time in ticks that remain until the stove runs out of fuel.
    • CookTime: Time in ticks that the current item has already been exposed to the heat of the oven. If it rises to 200 (10 seconds), the item is melted or fried. As soon as the stove runs out of fuel (BurnTime reaches 0), the CookTime is retained. When fuel is added, it continues to run.
    • CookTimeTotal: Time in ticks that the item needs to be melted or fried.
    • Items: List of item data in the oven with slot (from 0 to 2). Slot 0 contains the objects that are exposed to the heat, slot 1 contains the fuel, slot 2 contains the result.
    • RecipesUsedSize: Number of recipes last used with the same end product. Usually this is 1. But with a data package you can add further oven recipes for the same end product with different experience points. If you use these recipes alternately, the same end products pile up. So that the game can award the correct number of experience points when removing the end products, it remembers the number of end products for each different oven recipe until the end product is removed. Example: There is the original oven recipe minecraft.jar / data / minecraft / recipes / cactus_green.json for boiling cacti to cactus green, which is worth 1 experience point. Your own oven recipe .minecraft / saves / own-world-folder / datapacks / own-data-package / data / own-namespace / recipes / laub_zu_kaktusgruen.json boiling leaves to cactus green could bring you 2 experience points. If you boil leaves and a cactus three times, the game can correctly award the 7 experience points despite the change in raw material.
    • RecipeLocation0: Usually the name of the last oven recipe used. However, if you have recently alternately used different oven recipes for the same end product, these are noted with a consecutive number. In the example that would be RecipeLocation0: "own-namespace: laub_zu_kaktusgruen" and RecipeLocation1: "minecraft: cactus_green".
    • RecipeAmount0: The number of end products that were last made with the oven recipe of this consecutive number. In the example that would be RecipeAmount0: 3 (3 times RecipeLocation0 = Leaf recipe) and RecipeAmount1: 1 (1 time RecipeLocation1 = Cactus recipe).
