− | + | 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}}. | |
− | + | 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 | + | * 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 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 {{l|pump}}, except for the passable tile, provided that none of the components are made of wood. | ||

− | + | :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.
