Upon reading a recent thread on magma pumps, I was surprised to learn that Nethercaps have their temperature fixed at 10 000*U (a quick trip to the wiki confirmed this). 
Further research pointed me that 10 000*U is 0*C. 

Which makes me wonder if a fully lined Nethercap block floor with Nethercap supports will freeze water.  Does temperature work that way?


If no one knows, I'll test it out.  Perhaps water pumped through a nethercap pump will....

[ungulateman]

I believe so.

Even better, you can pump magma using nether-cap wood screw pumps.

[Scruga]

Is this for serious? We have some supercoldmaterial? o.o

[Internet Kraken]

What if I just built an artificial pond out of nether caps and then filled it with water? Would the water still freeze?

Gah, I should really breach the other cavern layers. Instead I have to keep mining bituminous coal since I only just found it on my embark site.

Bad news, I built a pond (with a roof) out of towercaps modded to have nethercap material statblock (interestingly, they were now called nethercap logs)
No freezing.  Pumped with (all) nethercap pump, nothing.  Filled the pond with supports made of nethercaps, nothing. 

Built the pond underground (filled with normal wood buckets), nothing. 

Checked to see temperature was on.  It was. 
EDIT: going to try modding the temperature to 0*U and seeing what happens. 

EDIT2: weird behaviour at 0*U.
The pond doesn't freeze. (even the one with the constructions)
When I tried to build a bucket out of 0*U nethercaps, the job completes but the bucket vanishes.  Just like that. 
I can build a workshop out of 0*U nethercaps just fine and it works normally. 

Built a bucket at 10 000*U normally.  Modding it to 0*U afterwards has no effect on it's operation.  Water in a 10 000*U or 0*U nethercap bucket does not freeze.  Going to make nethercaps boil at 1000*U with fixed temp 10 000*U just to for lolz.  I wonder what happens to underwater boiling wood...
Nothing apparently, everything not a construction made of nethercaps simply evapourates in red mist. 

EDIT3: Changing it to fixed temp 1001*U with boil at 1000*U.  Nothing.  Not even a wound.

I am excited at these prospects. Dwarven Ice hockey here I come.

Is temperature on? I suspect it is, but you might want to check.

[ElChad]

If Dwarves were able to attach blades to their feet. I'm pretty sure Hockey wouldn't be the first thought in a player's head. More like trying to find a way to train kicking.

Checked to see temperature was on.  It was. 

Well, I did check at the start and had to turn it on.  But all tests were conducted with temperature on.

Anyone know why things screw up (newly made buckets disappearing) at 0*U?

Well, at 0 Urist, your wood freezes.
But wait, there's more. Think about it. Wood. Freezing. The game has no reason, other than someone trying to freeze elves, to know what's frozen wood. And us being dwarves, we usually use the other spectrum of temperature to deal with the treehuggers - thusly, frozen wood is air.

[Schilcote]

I modded in a [FIXED_TEMP] material a while ago. It doesn't do anything noticeable outside of adventure mode's "it is cold" message.

[Grimlocke]

A temperature of 0 is nonsense, its way below the absolute minimum. I think 9508 urists is 0 Kelvin, might want to keep it above that to prevent oddness.

Only reason I can think of for the bucket disappearing is that it took damage form its own cold, but that would mean normal logs take that damage as well so I guess not.

I also remember reading that constructions dont emit temperature. Might want to try paved roads and such.

Didnt know that nethercaps were magmasafe though. Magma axles at last! I also just gotta try making a windmill at the bottom of a magmalake now.

[elwessweettea]

Under sufficiently cold temperature, all plant-based materials, including logs, will take damage. I had an embark once on 40d where I had 3 days to get everything underground: at the end of that time, my logs had gone from logs->xlogsx->XlogsX->XXlogsXX-> ; and so had my cloth, and my dwarves.

I filled the pond with supports made out of nethercaps.  =/

[Untelligent]

Maybe regular buildings don't affect temperature flows either. Try dropping regular ol' logs in the water.
