| Oct 23, 2018 at 20:44 | comment | added | user190081 | @BobD I think that that would be the case if the heat flux was the same between the liquid-air and liquid-ceramic interfaces, which I dont think is the case. Anyway, it would be interesting to build optimal-space-partition mugs (iopscience.iop.org/article/10.1088/1367-2630/18/10/103008/pdf). | |
