Well I guess the Caloric Stone was used to create Rubedo, as Rubedo is extraordinarily strong (can only be match by NPCs in the 8th floor + world class item.), and Ainz describes Rubedo as some kind of mechanical type character. Yet this is just a guess for now. I asked the author but he didn't answer XD
