<p>[QUOTE=&quot;desertgem, post: 983245, member: 15199&quot;]Gold Hydroxide is a substance that is not found in gold deposits or any metal exposed to air. It is manufactured under nitrogen gas by precipitating gold hydroxide from boiling aqua regia ( must be a fun lab) with 3N Potassium hydroxide, and then several more boiling acid baths until product produced ( still under nitrogen gas). It is a yellow brown substance. </p><p><br /></p><p>I think I was perhaos somewhat general when I said this in post #15</p><p><br /></p><p style="text-align: left"><span style="color: #000000"><br /></span></p> <p style="text-align: left"><span style="color: #000000"><br /></span></p> <p style="text-align: left"><span style="color: #000000">Gold does combine with other elements, but almost always under the extreme conditions not exposed to the air nor temperature/pressure of where you might store gold coins or whatever. I know of no boiling aqua regia naturally occurring on he surface of the earth in a pure nitrogen atmosphere.</span></p> <p style="text-align: left"><span style="color: #000000">Toning refers to a different color/appearance, and in this case it is &quot;red&quot; . So if the compounds mentioned in the OP are suspect, one must look for gold compounds that have a reddish color, and has a possibility of natural occurring.
