That's a very good question. I tried this very same plate in brass (actually 6 times) and keep tweaking my technique but I keep getting a void in the plate. I have cast some brass stars with success and yes you do have to get it hotter. It likes to start to set before the mold is filled if the mold is to big. I have only melted copper one time and poured a star but it was incomplete because I had to remove more dross (impurities) than I had planned for.
