<p>[QUOTE=&quot;Kentucky, post: 2512606, member: 33176&quot;]I am a novice at ancient coins, but I am a chemist and wanted to pass along some information:</p><p>Sodium sesquicarbonate is a double salt of sodium carbonate (washing soda) and sodium bicarbonate (baking soda) and a solution of the sesquicarbonate is the same as a solution of a mixture of the two.</p><p><br /></p><p>The original coin was very attractive, but the conservation method appears to have removed a lot of material and been detrimental to the appearance of the final coin.&nbsp; Too bad you can&#039;t start over, one of our members [USER=17261]@BadThad[/USER] has a product, VerdiCare, that stabilizes bronze disease with minimal coin damage.&nbsp; If you get some and apply it, I don&#039;t think it would hurt the appearance of the coin and might prove to be beneficial.&nbsp; Good luck with it.[/QUOTE]</p><p><br /></p>
