'''Magma-safe materials''' are materials which will not melt, burn or evaporate when in close contact with {{l|magma}}. Most frequently, this comes into play when using {{l|floodgate}}s operated by {{l|mechanism}}s.

In order to construct mechanisms from a magma-safe stone, simply ensure that they are the closest available stone to your {{l|mechanic}}, ideally by placing a restricted {{l|stockpile}} around your {{l|mechanic's workshop}}. {{L|Burrow}}s can also be of assistance here, as dwarves will not attempt to pick up stone out side of their burrow assignments. However, if you have an active metalworking industry and have access to {{L|iron}} or {{L|steel}}, constructing {{L|metal}} mechanisms is much more straightforward.

When linking a trigger to an object, the ''first'' mechanism selected is attached to the object, and the ''second'' is attached to the trigger. Unless the trigger itself will be submerged in magma (as could be the case with a {{l|pressure plate}}), only the first mechanism (attached to the object that will be submerged) need be magma-safe. If you do not have any magma-safe stones available, you can also work around floodgate-based flow control by using {{l|screw pump}}s to pump the magma over {{l|wall}}-barriers, or using water to form {{l|obsidian}} to plug flows and channel through them to reopen them (necessity and invention and all that).

Constructions that resist magma are:

* Constructions ({{l|Wall}}, {{l|Floor}}, {{l|Ramp}}, and {{l|Stairs}}) of any material can never melt or burn - there is nothing wrong with a {{l|wood}}en magma reservoir. Natural (but not constructed) {{l|ice}} walls/floors/ramps/stairs may melt however.
* {{l|Fortification}}s will allow the passage of {{l|magma}}, but not the assorted magma creatures. Fire snakes are vermin, so they can spawn anywhere near the magma. They are not affected by fortifications, grates, or even solid walls. Also, there is a bug with fluids which may sometimes let magma (and water) push living things through barriers such as fortifications, bars and grates. {{l|Pump}}s are a positive defense, but can change the dynamics of fluid {{l|pressure}}.
* If not submerged (that is, not opened to let magma flow over/past/around them), {{l|door}}s, {{l|floodgate}}s, and raised {{l|bridge}}s (provided that there is no magma on the space the bridge would occupy when lowered) of non-magma-safe stone or metal are safe. So long as they are just in contact with magma, only acting as a passive "wall", they are fine. If opened, they will melt.
** Raised drawbridges have a notable exception, in that allowing magma to flow over the center of the area that the bridge would normally occupy when lowered ''will'' cause the bridge's components to heat up and potentially melt.
* A {{L|pump}} made with magma-safe metal pipes and screws and with magma-safe metal blocks or magma-safe stone blocks is fully magma-safe. A pump made with glass pipes and screws or any type of{{Verify}} metal pipes and screws, and glass blocks, any type of metal blocks, or magma-safe stone blocks is magma-safe as long as no magma ever occupies the passable tile of the pump. Pumps made with {{L|wood}}en components will burst into flames the instant they are turned on, and pumps made with non-magma-safe stone blocks have been reported to melt after prolonged operation.

=== Glass ===
{{L|Glass}} behaves oddly in regards to magma. All types of glass are technically magma safe, based on a melting point of 13600 (the same as that of bauxite); however, small glass objects (such as {{L|instrument}}s) seem to be instantly destroyed if dropped in magma{{verify}}. So glass {{L|statue}}s, {{L|screw pump}}s, and {{L|floodgate}}s are all fine when submerged in magma.

Glass barriers still require magma-proof mechanisms to operate without deconstructing.

== Game calculations ==
In the game, magma's temperature is exactly 12,000 °{{l|Temperature scale|U}}, which is equivalent to 2,032°F, or about 1,111°C.

The chance of striking a magma-safe stone is roughly around 32%, not including the natural abundance of certain stone. It is important to note whether or not your fortress may already have access to magma-safe resources before attempting to deliberately find some.

==Magma-safe material==

The following materials will not melt when submerged in magma. Although true for any item/construction, it's worth specifically mentioning that this includes {{L|door}}s, {{L|floor hatch}}es, {{L|floodgate}}s, {{L|bridge}}s, {{L|screw pump}}s, and {{L|mechanism}}s.

'''Notes:'''
:1. Each stone is one of 16 {{L|color scheme|colors}} in the game. Different un-mined stone of the same color have a different symbol to distinguish between them. Once mined, the individual stones themselves can sometimes look identical if the color is the same. Use {{k|k}} to loo{{k|k}} at items or the terrain for specific information.

:2. '''°U''' = degrees in [[Urist]], the measure of temperature within the Dwarf Fortress world. As far as is known, there is no functional difference between a material that melts at 12,005°U or 55,000°U - they are both equally "magma safe".

:3. There are three iron ores in the game (four if you count {{L|goblin|goblinite}}). Of these, only {{l|hematite}} and {{L|magnetite}} are magma safe.

:4. Sphalerite has ''no'' melting point, but '''boils''' at 12,133°U - further research is necessary in this context - use at your own risk for the time being. This is accurate for the actual mineral, which sublimes at this temperature rather than having a liquid state, but how it behaves in Dwarf Fortress may be unclear.

:5. Nether-cap logs are naturally cold at 10000°U or 0°C, so it isn't affected by magma's heat. Full magma-safety still has to be confirmed.

Vidyabro:

Freezing {{l|climate|climates}} are among the climates available to embarking in. Choosing to embark in one poses an interesting challenge and substantial amounts of {{l|losing|fun}}.

== Settling ==
One of the first challenges presented by a freezing climate is the lack of [[water]], and instantaneous freezing of any exposed water. Water may be the hardest resource to come across, aside from trees, despite the abundance of ice chunks left behind while digging ice. Penetrating the first or so layer of ice may also prove difficult, as ice takes some time to dig. The are several ways to approach a freezing area. One of them is embarking with a [[volcano]] in site, utilizing the natural obsidian surrounding it to create [[magma-safe]] floodgates and mechanisms to effectively melt ice. Ice can be used to create buildings and workshops, as long as they are not melted by [[magma]] or other various sources of heat.

== Cautions ==
While channeling ice and magma, supervise your miners to ensure they are not encased in cooling magma.

:''A small bat-like creature with the head of an insect. It is found deep underground.''

This creature typically spawns in swarms. To give an idea of a single bugbat's strength, a dabbling hammerdwarf armed with a crossbow was able to kill one while receiving only minor injuries.
