Image size
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)

Fuel duration
Should each fuel have a list of how many bars it makes per fuel? e.g., Two sticks does one bar. –Preceding unsigned comment was added by 58.84.159.63 (Talk) 07:07, 8 March 2010. Please sign your posts with

Placement
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)

Inaccuracies?
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. –Preceding unsigned comment was added by Codewarrior (Talk&#124;Contribs) 08:51, 29 August 2010. Please sign your posts with
 * 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)

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 necessary 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, basically the first charcoal you create will use more wood as you lose out on the optimal efficiency of charcoal. –Preceding unsigned comment was added by Fghjconner (Talk&#124;Contribs) 15:12, 14 January 2011. Please sign your posts with


 * 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)

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

Lag in Multiplayer
I've 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 weren't 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)

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! –Preceding unsigned comment was added by 74.192.144.100 (Talk) 02:46, 6 October 2011. Please sign your posts with

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)


 * Ok since there was a problem in the smelting and lava pages as well, and I went and read up on pedantism, I've unbolded the names. (Cause I didn't realize that bolding is only for official names). I just wanted to note those names cause those are for the foods/clay. I made redirects from them, so people wouldn't be confused. Maybe you could try rewording it, but if its still confusing, then just remove it or move it to Trivia. (I mainly referenced them so people would know about it/find out/learn. Not meant to be confusing). - Asterick6 09:20, 21 November 2011 (UTC)

"Currently only available in"
This article starts as follows:

"A Furnace (or Oven or Kiln) is a special block currently only available in the Indev, Infdev, Alpha, Beta and Release versions of Minecraft."

Can we agree that this sounds, pretty much, like "almost every" version instead of "only in", and, also, that a list of names of old, now irrelevant, versions of Minecraft is not a good way to start an article about the furnace? –Preceding unsigned comment was added by 178.195.231.8 (Talk) 00:30, 15 December 2011.

Add Wooden Slabs

 * Could somebody confirm if from 1.2.5 Wooden slabs can be used in a furnace? The table on the Wiki page for the Furnace implies that they can be - but I cannot seem to use them as fuel? --Lx online 21:04, 20 June 2012 (UTC)


 * Just tested them on 1.2.5 as well. Wooden slabs cannot be used as fuel. Thefowles1 19:27, 21 June 2012 (UTC)


 * OK - I propose they are removed from the table on the actual Furnace page? Does anybody think they should stay? Lx online 16:27, 24 June 2012 (UTC)


 * There's a note saying they can only be used in 1.3 snapshots, not 1.2.5, so I don't see any reason to remove them. In general, the wiki documents snapshot features as they are added, rather than waiting for the official release. -- Orthotope 19:34, 24 June 2012 (UTC)

Smelting with no users online
Do furnaces continue smelting when a server is running but with no users online? I just logged on for the day from last night (about a 12 hour span) and all the items I began smelting last night were at the same progress as when I logged off. It's like they didn't keep smelting, despite the server still running. Thefowles1 19:30, 21 June 2012 (UTC)


 * Furnaces will only operate while the chunk they're in is loaded into memory. Depending on configuration/mods/etc., servers may keep the area around spawn loaded, as it's needed whenever someone logs in, but in general chunks are unloaded when no players are nearby. When no one is connected, most of the server is effectively paused. -- Orthotope 08:20, 22 June 2012 (UTC)


 * How about that, I had no idea. Thanks! Do you think it would be worthwhile to add that to the article? I couldn't find anything about that anywhere on the internet. Thefowles1 22:33, 22 June 2012 (UTC)


 * Possibly, though it's not specific to furnaces. Any time-dependent process – brewing, plants growing, baby animals aging, etc. – is affected the same way. -- Orthotope 11:49, 23 June 2012 (UTC)


 * Ah, okay, thanks again. Thefowles1 05:13, 24 June 2012 (UTC)

Furnace fuels video
Hello, I have recently made a quick video explaining all the different fuels for the furnace and how to use them efficiently. I admit that it is not the best video on youtube when it comes to the commentary, but no one on youtube has made a video explaining which items can be used as fuel, and often times newcomers as well as popular minecrafters dont know how to use the fuels to their potential, all the info i used for the video came from the wiki, the video is there for those people that dont really spend alot of time reading the wiki. I would just like to know if I need any special premission to link the video to the furnace page. I would very much like to contribute to the community.

 * It's still 100 in 1.3.2 . Since the maximum stack size is 64, you'll need to remove some smelted items and add more raw materials to make use of the entire burn time. -- Orthotope 19:49, 13 October 2012 (UTC)

1.8 Update: Which is true, the statement from here or on the update page?
Please explain why these seem to contradict. One says "pause" the other says "rewind at 2x speed". Which is true? One sounds great, the other sounds awful (your smelted products are unsmelted?! And the reverse happens at twice the speed they were smelted! Is this a "feature" or a "punishment"?)

This page:


 * Upcoming 1.8 	14w02a 	When a furnace runs out of fuel, the smelting progress will pause instead of resetting.

The Update page for 1.8 (link)


 * Furnaces: When a furnace runs out of fuel, the smelting progress will rewind at 2x speed

50.181.85.8 08:37, 2 March 2014 (UTC)


 * The 1.8 page is correct; this one had been missing a change from a later snapshot. Only the progress of the currently-smelting item is reversed; any finished items in the output slot (e.g., iron ingots) will remain. It's not as nice as pausing indefinitely, but still a bit better than the previous behavior of resetting completely as soon as it's out of fuel. -- Orthotopetalk 20:56, 2 March 2014 (UTC)

Exploding furnaces???
When I was new to minecraft, I found a furnace in a village. I was playing the PE edition, and since i was unexperienced I placed some fuel in the fuel slot and put a potato in the other slot, to see what it would make. After that, I decided i didnt want a baked potato and tried to get it back by tapping it, and the furnace exploded (killing me). Surprised, I rushed back to that spot in a few seconds and i found all my stuff scattered around (as usual when you die) but there was no damage at all, except the furnace had vanished. This happened a while ago and I recently found this wiki and decided to report this. Is this normal? Surely furnaces arent supposed to explode? I have tried many times to repeat this but every time i remove something when its half smelted, it crashes instead of exploding. Is this a bug? Im not sure which version this happened in, but i had tried to repeat it in the other version as well as the new one, but only crashing instead. I am almost certain this happened in the version before they added new fences and day/night cycles to creative mode. 24.57.126.46 00:20, 8 February 2015 (UTC)
 * In april fools update Minecraft 2.0, furnarces usually explode if overheated. However, this version was only released in Java edition and not in Pocket edition, so I guess this is some kind of bug. 85.76.86.234 06:07, 5 April 2018 (UTC)
