Magma-safe materials are known to include iron, steel, bauxite, fire imp bones and leather, nickel, nickel silver and adamantine, but currently it is difficult to control magma flow with floodgates since mechanisms must be made out of rocks, most of which are not magma-safe (Bauxite being the notable exception).
Mechanisms made from raw adamantine are magma-safe, and will properly operate a magma-safe floodgate in a magma channel. In order to construct mechanisms from raw adamantine, you must first allow its use for non-economic purposes in the stock screen (z and select 'stone'). You might wish to remove other stone-using jobs while adamantine is available for use.
If you are using bauxite, be sure to mark a stockpile around the mechanic's workshop which allows bauxite only.
The mechanism on the trigger need not be magma-safe, only the one on the floodgate. If you do not have any bauxite or adamantine available, you can also work around floodgate based flow control by opting for screw pumps to pump the magma over wall-barriers.
Calculations
According to the raw data files, magma's temperature is somewhere between 1300°C and 1400°C, which translates to 2300°F–2500°F .
Materials that resist magma are:
Earth:
- Constructions (Wall, Floor, Ramp, Stairs) can never melt or burn (there is nothing wrong with a wooden magma reservoir). Natural ice walls/floors/ramps/stairs may melt however.
- fortifications will allow the passage of magma, 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 anything else you might try to throw at them. 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. Pumps are a positive defense, but can change the dynamics of fluid pressure.
Metal:
- Nickel — 2600°F (1427°C)
- Nickel silver — 2600°F (1427°C)
- Iron — 2680°F (1471°C)
- Steel — 2710°F (1488°C)
- Platinum — 3000°F (1649°C)
- Adamantine — 15000°F (8315°C)
Stone:
- Bauxite — 3600°F (1982°C)
- Raw adamantine — 15000°F (8315°C)
Leather:
Bones:
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
