Zero thermal transfer between different gases

UPDATE: after some more time with the same colony, I can confirm thermal transfer is working halfway, at the very least. Placed a container full to the brim with ice and snow literally right next to a geyser, and I have yet to see any of it melt. Deconstructed the container to see if it helped any, and now I have a huge chunk of ice keeping its chilly -33°C to the geyser's 48 and surrounding CO2 44

 

EDIT: deconstructed the tile as well, so chunk of ice is sitting directly inside water at 55°C. After 45 cycles, not a single gram has melted, there is literally a 20,000kg chunk of ice sitting there.

I created an air vent between the swamp biome and the ice biome hoping to equalize their temperatures over time and the 40C air isn't denting the ice's -19C

When I let my dupes put ice in regular containers, it kept melting. When I made a dedicated container for ice, it stopped melting. I guess ice can only gain heat from other items stored in the container?

I use cold o2 that's evaporated from liquid in an area far away from where I dump my chlorine and co2 into the area to use the -200 air to freeze the unwanted gas so I really have no understanding of why yours isn't it may be just to small of a difference with the gasses your using

Would you call a 40°C/K difference "too small"? Also, when dunked directly into water (a pretty good heat conductor in the real world) that sits at a pipping hot 55°C, the ice keeps its frosty -30°C so that's an 85°C difference, or roughly two and a half times the stable temperature of the human body. Also water coming directly from a geyser doesn't lose half a degree either, both elements keep their respective temperature as thought they were covered in abyssalite (that ironically DOES adopt the temperature of igenous rock biomes)
