− | + | '''Magma-safe materials''' consist of [[pig iron]], [[iron]], [[steel]], [[nickel]], [[nickel silver]], [[platinum]], [[bauxite]], ([[raw adamantine|raw]]) [[adamantine]], and [[fire imp]] [[bones]] and [[leather]]. It can be difficult to control [[magma]] flow with [[floodgate]]s since [[mechanism]]s must be made out of [[rock]]s, almost none of which are magma-safe ([[bauxite]] and [[raw adamantine]] being the sole exceptions). | |

Note that although the above metals are all magma-safe, their [[ore]]s (excluding raw adamantine) are '''not''' - thus, while a [[platinum]] floodgate will operate properly in magma, [[native platinum]] mechanisms will melt after several seconds. | Note that although the above metals are all magma-safe, their [[ore]]s (excluding raw adamantine) are '''not''' - thus, while a [[platinum]] floodgate will operate properly in magma, [[native platinum]] mechanisms will melt after several seconds. | ||

To use raw adamantine, however, you must allow its use for non-economic purposes in the stock screen ({{key|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 [[pressure plate]]), 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 [[screw pump]]s to pump the magma over [[wall]]-barriers, or using water to form [[obsidian]] to plug flows and channel through them to reopen them (necessity and invention and all that). | + | When linking a trigger to an object, the ''first'' mechanism selected is attached to the object, and the ''second'' is attached to the trigger.

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. [[Pump]]s are a positive defense, but can change the dynamics of fluid [[pressure]]. | ||
* If not submerged (that is, not opened to let magma flow over/past/around them), [[door]]s, [[floodgate]]s, and raised [[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.
