when I sell my jewelry scrap to one of my large sources they add borax and sodium nitrate to the liquid gold with a large metal scoop , I am assuming this process is to their advantage and not mine.........am I correct?
the pin sample is taken of the liquid gold of which all karats have been mixed together and not only is the original non-gold portion still in the crucible but the amount of non-gold product in the crucible has been increased by the borax and sodium nitrate. When they take the pin sample I can see stuff swirling around the top of the cruicible , I assume this also is not helping my assay as it becomes part of the pin sample..........am I correct?
Thank you all for your kind assistance.
