What is the real thermal conductivity of abyssalite?

[Lilalaunekuh]

 

Here 3 setups with 3000K temperature (everything except the abyssalite it at 20°C) difference each:

A) Abyssalite inside 2Kg oxygen

B) Abyssalite with a ceramic tempshiftplate and a metal block (thermium)

C) Abyssalite next to a metal block (thermium)

 

Results:

A) Gasses and liquid got a x25 multiplier (if nothing change) so there is a temperature exchange happening

B) Even a low conductivity tempshift plate results in some temperature exchange

C)TOTAL INSULATION

 

If we decrease the temperature difference to 500K A) will be 100% insulated aswell.

(Each gas has it´s own minimum temperature difference to start conduct any heat. Just did the testing with O2,H2 and CO2.)

I'm pretty sure that multiplier is different nowadays, though I'm not sure how exactly does it work.

I've seen magma unable to change insulated block temperature, but CO2 above that magma heating up identical blocks to 300C.

Sorry, what is sweating?

I'm in the latest QoL beta and it seems to me that heat doesn't transfer from natural abyssalite blocks, UNLESS liquid touches them... I dug through oil through fossil, igneous, etc, to the abyssalite and the oil boiled against the abyssalite until the abyssalite dropped temp and equalised temp. Created petroleum and sour gas. But, a little oil on top of a bit hotter abyssalite does nothing... hmm... I'm thinking.. maybe it only happens if it's at/near a phase change temp, maybe? There's no temp equalisation to the gasses or solids or smaller amounts of liquid around. I don't sandbox, so not so easy to test. Maybe someone else could?

So maybe you should start using sandbox for testing purpose only and test by yourself? Why asking others to do things you can do too?

Some people enjoy testing out these theories. I think once I finally allow myself to sandbox I won't ever stop. It's a floodgates thing. I don't trust myself.

Nothing to be confused about. Once you allow cheat mode, you can't undo that.

Instant phase change in a material when in contact with a tile above its melting/boiling point.

It always happens in exactly 5kg portions. For example, if you have water on hot abyssalite, you will notice small pockets of steam bubbling through the water even if no big tile of water gets heated up noticeably. The abyssalite will cool to about 100C fast, then stop cooling altogether.

You can also often notice it in ice biome, where hot gas touches polluted ice tiles and makes them drip without completely melting.

So if that mechanic was the only one transferring heat, the 20°C thermium block next to my 3020°C abyssalite should have melted in small amounts.

(It´s >300K above the melting point)

I haven't seen solid-on-solid sweating so far.

May have something to do with displacement - sweating will not happen if the game doesn't know how to displace the fluids without deleting any. This can often block seemingly obvious sweating sites.

From what I can tell, sweating will always place the newly phase-changed material at the point where phase-changing material was (ie. 1000kg water will be displaced by 5kg steam), except in case of solids, where the sweating instead displaces the other material.

Heat transfer between magma and insulated tile is pretty confusing. I think Gurgel's assumption is most reasonable.

Doesn`t abyssalite melt at ~3700^oC? Same as tungsten?

PS: My point was about the thermium should "sweat" like a block of ice (it´s melting point is something below 2700°C)
