At home density test - Specific Gravity - repost from Jun 2024 Dry weight / Tared Submerged Weight = Specific Gravity The home version of this test isn’t perfect, but it can catch many of the common metal fakes. The ping on this one matches what I’ve learned to be Tin on a spectrum analyzer. Maybe a test error or it’s actually a Tin/Zinc hybrid? Maybe what I learned was wrong? For sure, not Silver. Fun test to play with, and of course, always best to use multiple testing methods. ***** If you or someone you know would like to test metals with a Pocket Pinger, they’re available on the link in the profile.
