Guys, guys, none of this solves the dilemma of stone. Every time one of my dwarfs creates something from stone, the product(s) always have less mass than from the boulder from which it(they) came. There is never any event where I take that stone back. Meanwhile, other than artifacts I never use platinum for anything but statues - statues with a greater mass than the bars used to create them. There is only one possible explanation: the fifth dimension only takes mass and gives mass; it cares not for elemental configuration. The mass that my stonecrafters send to fifth dimension when they create only 3 rings from a massive boulder is the very same mass reclaimed by my blacksmiths when they create a platinum statue with only 3 bars. It is clear, though, that there are limits to the dwarven mastery of the fifth dimension. After all, if they could just conjure any metal all willy-nilly, there would be no need to mine for ores and to smelt them. Clearly, some amount of the desired material must always be used in the construction of the item in order to retrieve the extra-dimensional mass. And then there is the matter of melting gains and losses which, apart from a few select items, somehow prevents the dwarfs from using the fifth dimension as a perfect philosopher's stone....
