Maybe the furnace picture should be smaller?--The Captain 16:13, 28 February 2010 (UTC)
 * Why?--Deepdata 12:56, 1 March 2010 (UTC)
 * Yeah, I don't see why the image should be smaller. Its a good size and shows the furnace in both states.--Quatroking - Garble Garble! 14:51, 1 March 2010 (UTC)

Should each fuel have a list of how many bars it makes per fuel? eg, Two sticks does one bar. - Thank you Deepdata for making the table. --Trippledot 07:20, 10 March 2010 (UTC)

Does anyone know how you control which way the opening faces? I can't get it to behave. --DStecks 18:33, 1 May 2010 (UTC)

--You simply need to place it with either it's back to one block or in between 3, never have it be surrounded by 2 because it'll somehow always go the WRONG direction to as you want to place it. Simplest way is to just surround the spot where you want to place your furnace with dirt and place it. Perhaps this should also be added to the guide somehow. --Alphasoldier 20:18, 1 May 2010 (UTC)

The page says, "However ... they are tedious to amass in any large quantities." about a block that is made from cobblestone. This is at least a little silly. - They take 8 cobblestone per furnace, which means only 8 furnaces per stack of cobblestone. This means that making them in large quantities not only takes up a lot of space but quite a bit of time, which is probably what the page refers to. --Strykar Zee 01:00, 29 September 2010 (UTC)

The ratio if 25 sand and 4 charcoal to 2 glass is no longer true BuddahcjccBuddahcjcc

Pictures
Any chance of getting pictures for the smelted objects, with same dimensions and such as in Crafting? Or, specifically, could someone link here with the pictures for glass and smooth-stone? I could use in Decorations_(Alpha). Thanks! --Arlnet 06:27, 1 August 2010 (UTC)

 * Yes!! Thanks! --Arlnet 08:28, 1 August 2010 (UTC)

furnace fuel
42 planks will smelt a stack. This has been added in.

Don't we need the note block's equivalent?

light
a burning furnace provides light

Furnace destroying the bucket when using lava as fuel
On the page it is stated that when you use lava as fuel for a furnace, it destroys also the bucket. This didn't actually happen for me and the bucket just got empty. Who can confirm this? --SloppyPwn 01:55, 19 December 2010 (UTC)
 * I just tested it with the latest Alpha release, and as soon as I started smelting, the bucket + lava was destroyed on the spot. - Bomb Bloke (Talk/Contribs) 03:34, 19 December 2010 (UTC)
 * With version 1.2_02 buckets are still being destroyed with the lava --MVaalH10:10, 9 February 2010

New texture of the top furnaces
Hello!! As a new feature of the "Beta 1.2 Update", the Furnaces have a new texture on the top (similar to the cobblestone). If is possible, It's necesary to add a image of the actual texture on the table in the article.

Ps: I hope my English is good, so I'm Spanish...

Thanks and good luck. Kingpowl 19:20, 13 January 2011 (UTC)

- I agree! I miss the old top though; I liked being able to hide mine in a floor of smooth stone Hotrian 04:09, 14 January 2011 (UTC)

-- DONE! They may not be EXACTLY like the previous images, but I tried to get them as close as possible. --KaizenNeko 23:38, 14 January 2011 (UTC)

Charcoal Duration
Charcoal duration was calculated by seeing that each charcoal costs 1 log to be smelted, plus 1/8th of itself (smelts 8 items I believe) so C = 1 + C/8. There fore, Charcoal costs 8/7 of a log. Burn duration of 80 divided by 8/7 gives 70 seconds per log. If this is incorrect, let me know.

--Fghjconner 22:35, 13 January 2011 (UTC)

This is true "at infinite". As long as you save back charcoal, your duration per log gets closer and closer to 70s (it's slightly lower than that to start with). To see this, imagine you have 4 logs. You turn one log into 4 planks, and then use 2 of the planks to convert 3 logs into 3 charcoal. Now you have 3 charcoal and two planks for a total burn time of 270s or 67.5s per log. Now imagine you have 7 logs. You take one of those logs and turn it into planks, and then you use those 4 planks to convert the other 6 logs into charcoal. This will give you a total burn time of 480s or 68.6s per log. Finally, pretend you have 55 logs. You convert one to 4 planks, then use the 4 planks to burn 6 logs into 6 charcoal. Then you use the 6 charcoal to burn the remaining 48 logs into charcoal, for a total burn time of 3840s or 69.8s per log. Basically, more you use the charcoal (instead of planks), the more efficient it gets, so long as you're careful to always use the charcoal completely up (always put 8 in, never fewer). There could be a rigorous mathematical proof here, but I'll omit it unless you're interested.

--Da5id 05:17, 14 January 2011 (UTC)

Yes, I understand, basicaly the first charcoal you create will use more wood as you lose out on the optimal eficiancy of charcoal.


 * I strongly disagree with this. You can burn ordinary coal to get charcoal out of a log.  Burning time from that log is 80 seconds. NoobSauce 22:02, 14 January 2011 (UTC)
 * But you have to use those 80s to make more charcoal, which isn't being "productive" burning. And you could use those 8 new charcoal for 640s of burning, but then you'd need more, so the last one gets used to make 8 more charcoal. And of those 8, the last one would need to be used for more charcoal, etc,etc. --JonTheMon 22:18, 14 January 2011 (UTC)
 * You need to take time to turn logs into planks and planks into sticks. I really don't think production time should affect "seconds per log".  NoobSauce 22:26, 14 January 2011 (UTC)
 * But you don't consume more than 1 wood to make those. and by "productive burning" I meant smelting ores, turning sand to glass, etc. --JonTheMon 22:31, 14 January 2011 (UTC)

I simply added the words "up to" before the per-log efficiency of charcoal. I think this will suffice for a casual answer of "how efficient is charcoal" because it really is quite close to 70s for relatively large numbers of logs. --Da5id 01:35, 15 January 2011 (UTC)

Oven should redirect to Furnace
Oven, aswell as other keywords should redirect to furnace

Coal Ore?
It mentions in the article that diamond ore can be smelted into diamonds. What about other ores that can only be obtained through hacking, like coal ore, redstone ore, and lapis lazuli ore? Has anyone tried smelting these? JesusChrist666 22:52, 3 March 2011 (UTC)JesusChrist666

Never mind, they don't work. JesusChrist666 21:12, 6 March 2011 (UTC)

Lag in Multiplayer
Ive experienced some serious lag while building a large underground room with furnaces as ceiling. It was supposed to be a big train station right beneath the spawn point, but made it impossible for most people to do anything there, some werent even able to get out, i had to port them away. As soon as i removed all the furnaces, everything went back to normal. Anyone else experiencing this? --Cass 13:49, 20 April 2011 (UTC)

furnace burn animation
even though my furnaces are completely empty (no fuel or objected to be smelted) but they are still showing the burning animation anyone else have this problem

Check if the fire picture is coloured, ghost PMSF 08:26, 13 July 2011 (UTC)

Glitch?
I was burning some sand, for glass, i was at almost empty fuel, i saved and quit to title, and i came back, fuel all full! (with fuel i mean that fire picture thing) Is this a Glitch? PMSF 08:26, 13 July 2011 (UTC)

Damn, when i paused it to write this it was back to normal :( PMSF 08:30, 13 July 2011 (UTC)

Lava (and other fuels) in 1.8
Playing the pre-release--I noticed it's taking longer than normal for this furnace to go out, the fire hasn't even gone down a tiny bit. I think it may power furnaces infinitely, or if not infinite, MUCH longer now. Can anyone confirm? 68.197.81.74 02:13, 10 September 2011 (UTC)

I was thinking the same, I've smelted well over 100 cobblestone and it hasn't budged, I hope it's infinite!

I noticed wooden planks seem to last twice as long, so perhaps lava is similar? I'll investigate later as i have several stacks of sand and cobble to convert over.

Naming
Asterick6: I disagree with your approach to furnaces. The furnace has only one in-game name (both in the tooltip and the GUI) and that is “Furnace”, not “Kiln” or “Oven”. Minecraft is not a perfect subset of real life, and we don't need to make distinctions that Minecraft itself does not make. I don't care if we decide to replace “smelting” with “heating” across the wiki, since the game doesn't give a name to the process, but I think that there should be only *one* name for the process, because it works the same for everything it can be done to. —KPReid 23:06, 17 November 2011 (UTC)
 * Yes the in-game name is Furnace, but you don't use furnaces to cook food, nor to burn wood or other non-ores. you use ovens and kilns to cook/bake food and bake clay, respectively. When we mention the furnace in food articles and clay articles, we should use Oven or Kiln because those are the names used for the "Heating device/Oven" for those types of items. This is just a general style that I believe we should use when referring to furnaces in context because you don't "smelt" food, nor do you "smelt" wood, nor do you "smelt" clay. Smelting refers specifically to the process of extracting the pure metals from the ores, and you use furnaces to do that, but you don't use furnaces to cook food or bake clay. There IS a difference, and you guys know it. - Asterick6 00:23, 18 November 2011 (UTC)
 * In Minecraft, you do use the block named Furnace to cook food. Minecraft is not reality, and this is not Wikipedia; our use of language should (a) match the text in-game and (b) make only gameplay-relevant distinctions. In terms of the gameplay and the in-game descriptions, there is no difference between the processing of ores, food, and clay. They all go into a Furnace along with fuel and take 10 seconds for each unit. As I said, I don't care what we call that 10-second operation (though I would prefer we not call it three different things), but there is no block in Minecraft called Kiln or Oven. Having additional names in order to match real life is as unnecessary in reference material as speculating on how Steve manages to carry tons of ore in his pockets, and confusing to the beginning player (who might think they need three separate blocks, or wonder where the crafting recipe for a Kiln is). —KPReid 04:43, 18 November 2011 (UTC)

I hope we can get some input from other editors on this issue. —KPReid 04:43, 18 November 2011 (UTC)
