[QUOTE="wiley coyote, post: 621941, member: 7587"] Hi Davent. Try heating the ingot until it's really hot , then lower it into a container of hydrochloric acid. This boils off the external coating of impurities on it. Each time you do it, the outer layer of gold becomes purer, and should become brighter. I was told this is a way of getting a better reading on a gold testing machine as it only reads the outer layer, which is now purer. Tie the ingot to about a metre of wire, with a metre long stick on the other end. This keeps you away from the reaction of the acid when the hot ingot hits it. Be careful. wiley. [/QUOTE]
