RE:CURIOUSITYThat's kinda creepy re: tracking devices. As for the moulds, we pour (and now repour to minimize that deleterious element effect) all in one day. So we use the 7 or 8 we have for the gold and slag. Before the moulds are fully seasoned, the geometry of the buttons are better than the bars (I once was at a 1st gold pour ceremony, and the bar got stuck!!), but after about 5 or 6 uses, it doesn't really matter. I'll ask our refinery guy if he has a particular preference, but I doubt it.
