One of my friends is working at the pawn shop and he had a customer who brought him a gold slab to sell. A monetary standard gold slab should weigh about 50 kilos and eventually it did, but he decided to drill a hole... After just less than millimeter of drilling the tin started to come up above the drill bit... What d'u think?
How to test if conductor is copper or silver based
Hi all,
Was wondering if anyone knows of any low-cost or no-cost procedure for testing if a conductor is copper or silver. I bought some banana plugs for cheap but claimed to be made of "pure" copper or silver. I am just curious if the claim is valid.
Thanks in advance,
Kenobi
