I want to make low grade gold bars. What is the best way to melt low gold grade material to make such a bar. I currently melt with some borax low gold material, mainly goldplate , stir a lot and I get bar with 2% gold content approximately. I have consistently felt the bars should be closer to 3% content as per my maths Am I doing something wrong. The mix is usually brass and goldplate ?
Thanks for any help
