Magma-safe materials consist of Template:L, Template:L, Template:L, Template:L, Template:L, Template:L, Template:L, (Template:L) Template:L, and Template:L Template:L and Template:L. It can be difficult to control Template:L flow with Template:Ls since Template:Ls must be made out of Template:Ls, almost none of which are magma-safe (Template:L and Template:L being the sole exceptions).

Note that although the above metals are all magma-safe, their Template:Ls (excluding raw adamantine) are not - thus, while a Template:L floodgate will operate properly in magma, Template:L mechanisms will melt after several seconds.

In order to construct mechanisms from bauxite, simply ensure that they are the closest available stone to your Template:L, ideally by placing a bauxite-only Template:L around your Template:L. To use raw adamantine, however, you must allow its use for non-economic purposes in the stock screen (z and select 'stone') - while doing this, you might want to suspend any other stone-using jobs.

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 Template:L), only the first mechanism (attached to the object that will be submerged) need be made of bauxite. If you do not have any bauxite or adamantine available, you can also work around floodgate based flow control by using Template:Ls to pump the magma over Template:L-barriers, or using water to form Template:L to plug flows and channel through them to reopen them (necessity and invention and all that).

Constructions that resist magma are:

• Constructions (Template:L, Template:L, Template:L, and Template:L) of any material can never melt or burn - there is nothing wrong with a Template:Len magma reservoir. Natural (but not constructed) Template:L walls/floors/ramps/stairs may melt however.
• Template:Ls will allow the passage of Template:L, but not the assorted magma creatures. Fire snakes are vermin, so they can spawn anywhere near their native biome - the magma pipe/pool. 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. Template:Ls are a positive defense, but can change the dynamics of fluid Template:L.
• If not submerged (that is, not opened to let magma flow over/past/around them), Template:Ls, Template:Ls, and raised Template:Ls (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 area that the bridge would normally occupy when lowered will cause the bridge's components to heat up and potentially melt.
• All parts of a Template:L, except for the passable tile, provided that none of the components are made of wood.

Glass

Glass behaves oddly in regards to magma. Glass is, in itself, not magma safe; glass instruments will melt in magma. However, glass furniture will not. So glass statues, screw pumps, and floodgates are all fine when submerged in magma. Forum link with experiments: http://www.bay12games.com/forum/index.php?topic=27423.msg333562#msg333562

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

Game calculations

In the game, magma's temperature is exactly 2,032°F, or about 1,111°C. This is also 12,000° Template:L.

Metal:

• Template:L — 2138°F (1170°C, 12106°U)
• Template:L and Template:L — 2651°F (1455°C, 12619°U)
• Template:L — 2750°F (1510°C, 12718°U)
• Template:L — 2800°F (1538°C, 12768°U)
• Template:L — 3214°F (1768°C, 13182°U)
• Template:L — 15032°F (8333°C, 25000°U)

Stone:

• Template:L — 3632°F (2000°C, 13600°U)
• Template:L — 15032°F (8333°C, 25000°U)

Leather:

• Template:L Template:L — 3532°F (1944°C, 13500°U)

Bones:

• Template:L Template:L — 3532°F (1944°C, 13500°U)
