Item-Solid Heat Transfer

In a vacuum if I drop hot ore onto cold metal I see the temperatures average out. Do you have a specific scenario in a save file that I could look at? Smaller is better if it's possible.

It appears I was wrong, it's a near vacuum that is fails to transfer, likely because it is transferring heat with the gas and doesn't check for objects it is touching anymore. Should I update the original post to reflect this?

 

In the attached file, the left volcano setup transfers extremely slowly, while the right rapidly.

The left has a near vacuum with just a kiss of hydrogen, and the right has a pure vacuum.

Ore now transfers heat with the ground at a lower rate than before but whether it is in a vacuum or not no longer has an effect. This should be a lot more consistent. Might not make today's patch if one goes out.

Thanks for reporting the scenario in such detail!
