Magma Problem
« on: November 06, 2014, 07:48:19 pm »

Okay so I have this nice little fort going next to a volcano.

I built a stairway all the way down to the level I want the magma at for my forges, I had a floodgate installed where the magma would flow and a level attached to it. So I channeled from above to release the magma at the topmost level and released the floodgate, filling a pit I had ready for the magma a number of levels below that.

But the magma kept filling up0, above the pit and I had to wall off a section of my fort or get flooded with magma. The floodgate didn't stay in place, it just flowed along the magma river I had made.

My problem is, I am not sure how to access the magma for forges without it filling up whatever I dig out when I channel into it where it has filled up my fort.

I hope that makes sense. Basically I need a way to block the path of the magma, and it has to be done from above.

Make it flow through a diagonal to neutralize the pressure, or else just build above the upper-most screwpump. It won't flood upwards if there's no pressure to force it up.

EDIT: Also it sounds like you used non-magma safe floodgates or mechanisms, magma is significantly hotter than fire and working with it requires the use of very specific materials like iron, glass, basalt, obsidian, etc. A shale mechanism will just melt and break the floodgate.

I used obsidian, the floodgate held until I flipped the lever then it went flying. I'm not using a screwpump, it's the natural flow of the magma. I've looked it over and I'm not sure I can install a screwpump. One side would have to be at level with the magma, and I can't get there without fiery death.

I don't have a way to take a screenshot, can you advise what would be the best way to do that?

I usually take my screenshots with PrtScr and then using IfanView paste (ctrl+v) it for editing. Clunky but useable.

Both the gate and the mechanism should be magma safe.

Ahh the mechanism must not have been magma safe.

Goblins overwhelmed my fort anyway but now I know better.

If you're not using a screwpump, the pressure will push the magma up until it reaches the level of magma in the volcano (which, iirc, refills). You need a screwpump or a diagonal tile to undo the pressure.
