History[edit | edit source]

0.31 January 29, 2010 Prior to the addition of furnaces, items could be smelted by dropping them on the ground and then burning them with flint and steel. This was the only way to smelt ores.[1]
February 19, 2010 Furnace added.
February 23, 2010 The first smeltable item is cobblestone, which can be smelted into smooth stone.
March 20, 2010 Furnace is now fully functional.
1.2.0 Furnaces will face towards the player when placed,[2] rather than away.
1.2 The top of furnaces have a texture similar to cobblestone. They used to have a texture exactly the same as stone.
Official release
1.0.0 Beta 1.9-pre1 Furnaces do not take as long to destroy.
1.2.4 Cats will try to sit on active furnaces, making them unusable. This is only meant to annoy the player.
1.2.5 1.2.5-pre Shift-clicking can be used to put items into furnaces more easily.
1.3.1 12w18a Wooden tools work in furnaces as one full furnace use.
12w22a Smelting various ores in furnaces now rewards players with experience points.
When using lava for fuel you get the bucket back.
1.4.2 12w39a Previously, furnaces lit up blocks all around them, this snapshot made furnaces light up blocks only in front of them.[3] (images showing difference) Its light value remained 13, but the light is only emitted from the block's front surface.
12w40a The previous change was reverted until the new lighting system could be optimized.
1.4.6 12w49a When holding sneak, the player can place blocks and items (like redstone, repeaters, and levers) directly onto furnaces.
1.5 13w02a Furnaces renamed using an anvil will display the new name in their GUI where the normal name used to appear.
1.8 14w02a When a furnace runs out of fuel, the smelting progress will pause instead of resetting.
14w04a When a furnace runs out of fuel, the smelting progress will now reverse at twice the speed of smelting.
14w26a Furnaces allow only fuel or a single empty bucket in the fuel slot.
Pocket Edition Alpha
0.3.2 Furnaces added, meaning that every available block and item can now be gathered, crafted or smelted into. (no more unlimited items).
0.9.0 build 1 Furnaces now naturally spawn in villages.
0.11.0 build 3 Furnaces now drop one stack for each item instead of splitting them up.
Console Edition
TU1 Added furnaces.
TU12 Cats will try to sit on active furnaces, making them unusable. This is only meant to annoy the player.
TU14 Wooden tools work in furnaces as one full furnace use.
When using lava for fuel you get the bucket back.
Pi Edition

Trivia[edit | edit source]

  • Furnaces function as multiple devices combined into one block: bloomeries and blast furnaces (for smelting ores), an oven (for baking and cooking), a charcoal pit (for the charring of wood) and a kiln (for baking of clay).
