Given the technological development of the era Tolkien used as a reference for his opus ... one should not be able to handle or transport any molten metal or rock (lava!) in batches biggercthan cup size in liquid containers overcany distance. Pooring melts directly from a crucible into a gutter will have been possible, and dwarves may have perfected this to enabled them to melt larger volumes, at higher temperatures and to cast the melts in multiple moulds simultaneously, through hard rock or even metal gutter systems. Bucket transport or sufficiently insulated and resistant piping ... just forget it.
