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.

: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? I'd like to know if it's entirely random or if there is some order or pattern to it.

::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.

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.

The example directly on the page is difficult to understand--some diagrams would be helpful. Really, detailed designs like that should be on user pages anyway.

Nope, sorry - I may not have the whole definition, but your limits are just wrong. I noticed "lava" underground while piercing an aquifer. It had been pumped down from the surface, but it was then underground, and had overflow from making obsidian on water onto a floor tile - and none of the other magma doing the work was "lava", it was all "magma". So was every bit of the magma vent that was exposed. So... I don't know where that leaves us, but for now neither may be (completely) right.--[[User:Albedo|Albedo]] 05:55, 28 September 2009 (UTC) | Nope, sorry - I may not have the whole definition, but your limits are just wrong.
