I doubt you need anyone telling you that, but make sure to not disturb the surface too much once you get those two molten together. Zinc is crazy eager to oxidise in those conditions, which, once started, causes even more disturbances and splashing. Plus everything around it will be covered in that yellow crap.My buddy suggested that if I was feeling bold I could savage some old batteries for the zinc, melt it down and cast my own brass.
Yeah I've kinda lost interest in savaging batteries. I've got eight pounds of Zamak 2 but I'm not sure what to do with it. I'm told that it doesn't melt hot enough to thermally shock the investment so if I want to make a rock with a nickel center I should try treating this shit like bronze and see what happens.
