How to work gold when it is porous and cracking? • https://www.jewelry-tutorials.com/met... • The porous cracked placer gold issue is solved by melting the gold bar at high heat several times. • Then eventually cutting the gold bar into smaller sections and melt again, so that the heat gets to the impurities more evenly. • I used a large amount of potassium nitrate, which reacts with base metals, effectively removing them from the melt. • Stirring with a carbon rod also draws the impurities out.
