Magma is ''extremely'' hot which can lead to even more [[fun]]. Workers that dig into a magma reservoir are not instantly killed as the magma touches them, but they are set on fire, which will kill them very quickly. For this reason, taking steps to ensure there is adequate water available to extinguish flaming dwarves running in random directions is advised before digging into any magma pools from the side. Channeling a single square wide pit across the planned magma pipe one tile away from the wall to breach and filling it with water using the [[Activity zone#Pit/Pond|pond zone]] tool is recommended, so the panicking dwarves have no choice but to run through the water, and the water itself turns into an obsidian wall as soon as the magma flows into it. |

Magma never cools, but can [[evaporation|evaporate]] if left at a depth of 1/7 for long enough. When magma is mixed with water it forms [[obsidian]].

A pipe to bring magma across the full map can take as much as a year to fill. This, combined with the fact that it will [[Evaporation|evaporate]], can make filling a reservior difficult and tedious. As a rule of thumb, the area coming out of a 1-wide-pipe shouldn't be more than three squares wide and 20 squares long, or else it will evaporate as fast as you fill it. |

Pump stacks are conceptually the simplest, but require an enormous amount of in-game time to make. Magma pistons tend to be faster to make, but require more time to understand how to build them. |

− | + | Although the name suggests them as pools, they are actually pipes (Unknown why Toady changed the name). They can be found underground, however they rarely reach the upper z-levels (40+). Most end just a few z-levels above the magma sea, though some may span more than 100 z-levels. | |
− | + | Magma pools seem to be always connected to a magma sea, and the sea and pipe can occasionally reach up to the same level, making them hard to separate. However, magma pools can be identified by the obsidian walls which surround them. | |
