v0.31:Ice
| This article is about an older version of DF. |
Ice as a stone
Ice appears as a light blue stone which can be found by mining through an ice wall (such as that created when a river freezes). Ice boulders and objects made of ice will melt after some time when exposed to warmer temperatures (such as inside a fortress), giving it rather limited use; ice boulders can even melt while being carried by your dwarves, causing them to drop the item and resulting in a smear of water on the floor beneath them.
It is possible to build Template:Ls out of ice, even inside a fortress (provided your dwarves move quickly enough to finish construction before the ice melts). These constructions are then stable even as temperature rises (some expections- archery range) -- pillars of ice walls can even be built within rooms that are later flooded with Template:L (though the walls become "warm", they will not melt).
Attempts to build Template:Ls out of ice will usually result in the ice melting immediately, a message "The dwarves were unable to complete the [workshop_name]", and the workshop construction being canceled completely. The exception is when building in a glacier environment the construction can be completed.
Ice cannot be used to craft. It's not possible to create doors, hatches, and other crafts from it.
The game refers to ice boulders as "water." It does not appear in any stockpile options or the manager, so it cannot be moved by designating a stockpile. Ice can be moved by Template:Ling it.
When ice melts inside a fortress, it becomes water, but the water does not leave mud when it evaporates. Melted ice is of no value as a water source.
Floors and walls made of ice will allow light through.
Thawing and drowning
In fortress mode, frozen Template:Ls will, when they thaw, do so instantly. Any dwarf standing on the ice will plunge into the water and drown (unless they have Adequate or better Template:L skill, the fall will Template:L them). To reduce the chance of this happening, you can use Template:L designations: mark the ice as restricted, and put a high traffic ring around the perimeter of the pool. Or, if you don't need to Template:L from it, you can Template:L a Template:L around it or a Template:L over it.
Running magma under unmined ice will melt the ice. This appears to be the best way to turn large amounts of ice into water to use as a water source when all you have is ice and magma.
Differences from previous versions
Squares which have had constructions built on them do not unfreeze (bug?)
Constructing around ice
Using the smooth stone and carve fortification designations work as normal with ice. However, if an Template:L or other source of water is present next to your new fortification, it will immediately freeze into an ice wall when the water flows into it.
