i think its only similitude in names, not same caloric stone from yggrasil

yggrassil caloric stone ar emade with combining ores from 7 diffrent hidden mines that have super rare metal and give worlt item metal

the caloric stone dwarves use  is just like coal, it just used for heat, since wood and coal generate lot of smoke and CO2, it'll kill them, they cant use it underground in caves tunnels
