<p>[QUOTE=&quot;ArtDeco, post: 8396708, member: 119259&quot;]The difference I believe is the rate in which the silver is reacting, with the envelope method there should be a specific type of light toning (that can change colors) that is more subtle than a coin that would change color more rapidly in the presence of a more substantial amount of sulfur the coin is exposed to with the mashed egg, liver of sulfur or other chemical methods.</p><p><br /></p><p>I mentioned earlier on this thread that I had done an experiment where I used liver of sulfur in cold water, with cold water the reaction doesn&#039;t start on the silver but as I added small amounts of boiling water into the mix one at a time, the jewelry started turning from a orange golden hue to a sharp light blue to a charcoal black color, I was able to do a variety of colors by slowing the reaction down on pinch at a time when I added the small amounts of boiling water.</p><p><br /></p><p>The coins develop subtle toning in a variety of colors due to the exposure of the trace amounts of sulfur in the envelopes unlike the instant blackening you get with something like mashed eggs or liver of sulfur+boiling water.</p><p>From the photos I&#039;ve seen from the envelope method, the toning is more natural looking and most I&#039;ve seen that have had the egg or chemical method done tended to look more &quot;exaggerated&quot;.[/QUOTE]</p><p><br /></p>
