Yeah, I know the feeling. I haven't accidentally any bronze in my current Pathfinder playthrough, but I did make a good bit of invar and electrum. I've used up all the invar by now, but there's still a dozen or so electrum ingots sitting in my chest.
Once, I realized that I was about to make some of that electrum a split-second before the silver melted when there was already some molten gold in the smeltery. I tried to pull it back out, but it was too late.
