Magma is ''extremely'' hot which can lead to a lot of {{L|fun}}. In the current version magma seems a bit slower to burn things. Workers that dig into a magma reservoir are not instantly killed as the magma touches them and can often scramble to safety{{verify}} as long as they are not fully immersed in 7/7 magma. It's worth noting that magma never seems to blink with {{l|flow}} now either. |

Magma never cools, but can {{L|evaporation|evaporate}} if left at a depth of 1/7 for long enough. When magma is mixed with water it forms {{L|obsidian}}. Note that magma located above {{L|semi-molten rock}} will be listed as a Magma Flow and cannot be cooled into {{L|Obsidian}}. |
− | + | === Bringing Magma Up === | |
− | + | Magma can be brought to the surface by two different methods:{{L|pump|pump stack}}s, and magma pistons. 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. | |
− | + | ==== Pump stacks ==== | |
+ | Pumping magma up from the magma sea via a conventional {{L|pump|pump stack}} is a lot of work, requiring hundreds of pumps and vast amounts of power. Making all of the pumps {{L|magma safe}} also requires a lot of precious materials like steel or glass. | ||
− | === | + | ==== Magma pistons ==== |
− | + | {{L|Magma pistons}} are another way to move magma near the surface. Magma pistons require less time and fewer precious materials to construct than pump stacks. However, magma pistons are a bit more complicated than pump stacks, so it takes more time to understand how to operate and 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. | Although the name suggests them as pools, they are actually pipes (Unknown why Toady changed the name).

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. | 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.

Magma will turn into {{l|obsidian}}<sup>1</sup> if it touches {{l|water}}. In the game, magma's temperature is 12,000 (2,032°F, or about 1,111°C).

Tiles directly adjacent to magma will be heated to a temperature of 10,075 (107°F, or about 42°C), causing revealed unmined tiles to flash with {{Tile|☼|6:4:1}} when placing digging designations and causing unrevealed mining-designated tiles to cancel their designation (with a "warm stone" warning) once they are revealed. | Tiles directly adjacent to magma will be heated to a temperature of 10,075 (107°F, or about 42°C), causing revealed unmined tiles to flash with {{Tile|☼|6:4:1}} when placing digging designations and causing unrevealed mining-designated tiles to cancel their designation (with a "warm stone" warning) once they are revealed. | ||

Unlike how waterfalls create mist magmafalls create no magma mist, yet if some debris from a [[cave-in]] lands in some magma a deadly cloud of [[magma mist]] is released. | Unlike how waterfalls create mist magmafalls create no magma mist, yet if some debris from a [[cave-in]] lands in some magma a deadly cloud of [[magma mist]] is released. | ||
