Are you certain that steel is a requirement for metals in contact with magma? This info conflicts with the [[Magma smelter]] article, which state that using [[Fire-safe materials]] is enough. Don't have a fort with magma yet, but could someone check which one is correct?[[User:Thexor|Thexor]] 19:23, 31 October 2007 (EDT) | Are you certain that steel is a requirement for metals in contact with magma?

:Magmaproof is not the same as fireproof. Buildings that work WITH magma need to be fireproof. Rocks and iron are fireproof. Wood is not. Buildings that are going IN the magma, such as floodgates, their mechanisms, and pumps need to be magmaproof materials such as steel and bauxite.

If i disable temperature can my dwarfs swim through the magma unharmed? Will it still cause water to steam?

: Yes, dwarves seem to be able to swim through magma unharmed when temperature is off(I've had them shoved in during a fight, not 100% sure), but they'll violently resist this, even without danger. Water will still steam, it seems to be hard coded. --[[User:Erathoniel|Erathoniel]] 16:50, 12 November 2008 (EST) | : Yes, dwarves seem to be able to swim through magma unharmed when temperature is off(I've had them shoved in during a fight, not 100% sure), but they'll violently resist this, even without danger.

Does the type of rock around the mountainous areas hint at magma? If you check out [http://en.wikipedia.org/wiki/Volcanic_rocks#Naming this article] and [http://en.wikipedia.org/wiki/Igneous_rock#Mineralogical_classification this site] list a bunch of common volcanic rocks: Granite, Rhyolite, Diorite, Andesite, Gabbro, Basalt, Peridotite and Komatite. Perhaps some clues as to where to find magma? | Does the type of rock around the mountainous areas hint at magma?

:It may be possible to find magma vents by searching for extrusive igneous rocks (such as basalt, felsite, rhyolite and andesite), but continental shelves and deep earth are just naturally made of intrusive igneous rock (such as granite, diorite and gabbro). It's generally indicative of rock that has been pushed up to the surface (or erosion has withered the rock down), and not a volcano. | :It may be possible to find magma vents by searching for extrusive igneous rocks (such as basalt, felsite, rhyolite and andesite), but continental shelves and deep earth are just naturally made of intrusive igneous rock (such as granite, diorite and gabbro).

::So areas with surface igneous rocks such as basalt, felsite, rhyolite and andesite have a high chance of finding a source of magma below the surface?

On a completely different topic: I keep setting up on magma vents but not actually having a magma chamber visible. I assumed one problem was the lack of a border on my plot (so somehow the volcano was actually outside my plot), but even after making it bigger there was still no magma (...but it did have a fancy cave)...This has happened the last 4 times I've tried to start on a volcano, and the world regenerating takes quite a while for ~10 named volcanoes, and then all of the livable ones don't actually have magma.--[[User:UltimaGecko|UltimaGecko]] 16:50, 3 November 2007 (EDT) | On a completely different topic: I keep setting up on magma vents but not actually having a magma chamber visible.

:You might try using reveal.exe to see if the volcano is underground. I just built on a site with a volcano which was not visible from the surface, and used reveal to make sure I hadn't lost my mind (then I killed DF and restarted it so I wouldn't still have the map revealed) - The volcano was entirely underground, covered by layer(s) of rock. I've also added a note to the article saying that it is possible to find a volcano which is visible on the starting screen but not from the surface on-site.--[[User:SL|SL]] 21:54, 7 November 2007 (EST) | :You might try using reveal.exe to see if the volcano is underground.

::I think this is related to the temperature of the area. I've got a map with a magma vent in the middle of a glacier. There was no surface magma, but there was a nice flat, round patch of obsidian surrounded by ice. After digging down three levels through this "cap", I hit live magma. It's actually a nice setup, as I've basically set up a small fort *in* the cap--basically my dwarves are living in the mouth of the volcano, with the basement level dedicated to magma smelters, forges, glass furnaces, etc. --[[User:RedKing|RedKing]] 04:26, 9 November 2007 (EST) | ::I think this is related to the temperature of the area.

Zara, you recently added some info about all magma pipes having cliffs over them -- this is incorrect. I've played a very large number of magma pipe maps, and very often they are completely exposed to the air. I've also removed the line about them being "as small as two z-levels!", because it needs better phrasing. I may fix it later.

This is what I've found: ANY Construction is safe from magma (even wooden ones. Walls, stairs, fortifications, etc). Any building is unaffected by magma if the magma doesn't occupy the same tile as the building. Example: a door is safe if it's closed, even if it's made of non-safe rock or wood. If you lock it open with a mechanism, or if it's jammed, then the magma interacts with the components, burning/melting them if they can't stand the heat. A pump made of wood or any other material is also safe, as long as the magma doesn't flow *over* it. Since the "out" side acts as a wall, if it's correctly isolated from the magma it won't get damaged and will pump the magma without any trouble. --[[User:Sergius|Sergius]] 01:41, 21 May 2008 (EDT) | This is what I've found: ANY Construction is safe from magma (even wooden ones.

I have a very good feeling that the replenishing magma is just "pressurized" magma. I haven't tested fully, but i have poured water over a magma pipe and re-mined it, and in that case the magma flow was upwards. --[[User:Sphexx|Sphexx]] 03:49, 23 May 2008 (EDT) | I have a very good feeling that the replenishing magma is just "pressurized" magma.

:::Tested this by a) dropping (non-magma safe) rocks into a river and then pouring in Lava, they were recoverable. b) putting a couple of similar rocks as well as a nickel-silver bar and a constructed nickle-silver bridge into a room, letting enough magma in to cover the floor, and then adding water before the rocks had melted. All items were recoverable and the bridge was still intact after digging it out. --[[User:Mael|Mael]] 00:08, 15 July 2009 (UTC) | :::Tested this by a) dropping (non-magma safe) rocks into a river and then pouring in Lava, they were recoverable. b) putting a couple of similar rocks as well as a nickel-silver bar and a constructed nickle-silver bridge into a room, letting enough magma in to cover the floor, and then adding water before the rocks had melted.

I don't know why, but I've observed flies (normal and acorn flies, mostly normal flies) spawning at the edge of magma where its melting rock. It's particularily noticeable when you have magma channels under your forging area since the confined space tends to concentrate them. Also, they will come out of any magma access holes you have dug. I'm using the Mayday graphics mod, so no idea if it's an artifact. My theory is that they represent vapors coming out of the magma as it melts the rock it encounters. I also added this fact to the flies page as well. --[[User:Smjjames|Smjjames]] 14:14, 13 May 2009 (UTC) | I don't know why, but I've observed flies (normal and acorn flies, mostly normal flies) spawning at the edge of magma where its melting rock.
