Scratch tests metal content
Would love to have a quick discussion about scratch test for testing, gold and silver as well as analyzing metal content. I do of course have a scratch test kiss I sometimes wonder if it’s 100% accurate it is scratch. I have replaced it recently also wondering does anyone know about XRF? I mean I know those machines are super expensive but Brad do you have one? Thanks in advance everyone
