Editing 40d Talk:Magma forge

== Operational Magma Depth ==
More specifically, "nearby" means that at least one of its eight edge squares hangs over a hole which has magma at a depth of at least 4 on the level below. <br />
:Verify - I've got a magma forge at the moment over 3 lava squares and it's not working, while the smelter next to it is. I think the building has to have at least one of those red circles over lava. Juckto 15:48, 14 November 2007 (EST)
::Sorry for moving this comment off the actual page, but this sort of thing is supposed to go in Talk. Anyway, I'm 100% certain of this information. 
::Firstly, you're wrong about the "building has to have at least one red circle over lava" bit; the game explicitly says "At least one of the eight boundary squares must be over lava" when a magma building is not operational, and I've built a working magma forge whose upper-left corner is the only part over magma.
::Secondly, I built a tube to get magma over to my mineral deposits, on the other side of the map. I built a bunch of smelters and a couple of magma forges over it, and noticed that eventually they started flickering on and off. When I looked underneath, I saw that the entire tube in the area was at a depth of three or four, and the depths were shifting around like they do in water. The workshops only turned on when the depth under their open square was four.
::It's possible that if a magma workshop has more than one open area, the depth required to operate it is reduced. I wouldn't know. [[User:Tacroy|Tacroy]] 18:55, 14 November 2007 (EST)

::Juckto, make sure the building is built over a channel square with lava in it, there actually needs to be a hole in the ground for the forges to operate. I didn't realise this at first and had to reassemble my workshops after some digging. [[User:Jimphraxia|Jimphraxia]] 12:17, 28 November 2007 (EST)

===Best position for channel===
Am I right that if I build the channel where the darker X's are going to be then equipment will cover up the hole in the ground preventing Magma Men etc from coming into the workshop?[[User:GarrieIrons|GarrieIrons]] 00:55, 23 June 2008 (EDT)

== Magma only? ==

Out of curiousity, does ''lava'' work as well with the ''magma'' forge? As magma turns to lava once exposed to the outside, I wonder if the magma forge might still recognise it as compatible. This might explain why juckto above did not get it to work. --[[User:Nexii Malthus|Nexii Malthus]] 19:04, 8 March 2008 (EST)

:ive always built my magma buildings up on the surface(and thus over lava) and they work just fine --[[User:Chariot|Chariot]] 06:53, 9 March 2008 (EDT)

::lava = magma above ground level. it's the same stuff.[[User:GarrieIrons|GarrieIrons]] 00:53, 23 June 2008 (EDT)

== Z-levels? ==

I was just reading the entry because I'm getting ready to set up my first magma forge. However, I'm not clear (and the article is also unclear) as to whether these can be built many Z-levels above magma, or if they have to be exactly 1 Z-level above the magma channel. For instance, I have a nice rock outcropping above a volcano on my map. Can I build a magma forge in there (effectively 2 Z-levels above the actual magma) as long as I have 'open space'?
I mean, does it work like a well, where no matter how high above the water you are, you can get to it as long as there's a chute? --[[User:Vix0r|Vix0r]] 22:34, 19 June 2008 (EDT)
:I'm 99% sure you to have the forge the next z-level up from the magma. I imagine the forge is much more like a screw pump or a waterwheel than a well but can't say I've really tried the skyscraper forge method. If you build the forge and the furnace turns red, then the magma is fueling the forge, if not then something is preventing it. --[[User:Kyace|Kyace]] 22:58, 19 June 2008 (EDT)
::It appears that magma forges ''are'' more like screw pumps than wells. What a disappointment. :| --[[User:Vix0r|Vix0r]] 00:14, 20 June 2008 (EDT)
:::I'm not sure what the official policy for the wiki, but it might be simpler to merely edit the well article with "Wells are currently the only construction able to access materials more than one z-level below". --[[User:Kyace|Kyace]] 02:49, 20 June 2008 (EDT)
::::In the interests of helping players curious/confused about magma forges themselves, I think this is a better move. Someone curious about how magma forges work isn't likely to check the wells page. --[[User:Vix0r|Vix0r]] 16:49, 20 June 2008 (EDT)
:New Player here...I definitely built mine 3 z levels above "magma flow," which I assume is the acrual magma level, because the ones above it all say "open space"--[[Special:Contributions/71.88.42.179|71.88.42.179]] 08:07, 14 May 2013 (UTC)
::Are you using 40d? If you're using the latest version (0.34.11), you should post this [[DF2012 Talk:Magma forge|here]] instead. Also, I'm pretty sure that, while you can build a '''magma''' forge anywhere the forge only ''works'' when it's 1 level above the magma (at least in 0.34; I'm not sure about 40d, but this discussion seems to imply the same). (Also a little note – the levels above the forge won't affect the forge, but the levels ''below'' will). --{{User:Lethosor/sig}} 20:05, 14 May 2013 (UTC)

== Blocks/bars as building material ==

It says "verify" for blocks and metal blocks as a building materials for magma forges, and as I was building one anyways I figured I'd check.  I built mine out of a cinnabar block, and various metal bars were also in the list of usable materials for construction.  (v 0.28.181.40d)
