Obsidian farming is a method of producing Template:L efficiently. When Template:L contacts Template:L, a tile of unworked obsidian spawns on the meeting point and both fluids disappear (from that tile). Obsidian is a valuable Template:L and both magma and water are renewable.
A typical method of farming is as follows:
- A rectangle hall, 2 z-levels high is dug out/constructed
- Lower level of the hall is fed magma from a pump (otherwise it will fill very slowly)
- Upper level of the hall is covered in water (pump is a good idea too)
- Water gets removed (by a pump, opened floodgate etc.)
- Resulting obsidian (on the lower level) is designated for ramping or channeling (floor between levels needs to be removed for the farm to be reused)
For more advanced farms, one can have few layers of magma and water - each new layer adds another layer of obsidian, so this method is far more efficient (N - number of fluid layers, (N-1) - number of obsidian layers). Your dwarven ingenuity should be shouting "OBSIDIAN FORTRESS" by now, by the way.
Try to avoid "free" magma tiles. Magma pump should pump directly into the hall, not into a tunnel leading to the hall. Results of doing otherwise include Template:L, Template:L and Template:Ls when the obsidian is being dug out, unless the tunnel itself is sealed (with a floodgate, for example) before collection of the precious black stone (actually volcanic glass). Same tip applies to water pumps in case of obsidian fortress, except this time the only danger is Template:L and annoying messages.
Note that if you add water to a tile which is as little as 1/7th full of magma, you'll create a full block of obsidian. This is particularly useful when you're operating a repeatable magma piston since one block of obsidian will displace 7/7 units of magma, and you'll only need 1-2 units of magma to make a block of obsidian to get 7 units of magma...
