I just tried smelting adamantine and it gave me molten promethium. then tried smelting atlarus and got rubracium. so i experimented further by just giving me blocks of many of the different metals, and smelting any of them gives a different molten version. then if you pour the liquid into a casting basin you either get ehe original metal you had or something completely different. Not sure how this happened. i havnt fiddled with the config file or anything or added any mods to my modpack besides bibliocraft.
