<p>[QUOTE="terry5732, post: 414820, member: 42"]"Shibuichi is primarily copper and silver in varying proportions, again dependant on the color desired. The silver percentage can range from 2% to 60% or more, but more often would fall in the 15 to 40% range. These percentages are not haphazard, but are calculated for a specific color result based on centuries of experience. Shibuichi patinated with the traditional Japanese irotsuke technique offers a wide range of grays <b>with some browns</b> when using very low silver content. Pure gold and silver are not affected by the irotsuke chemical patination so retain their natural raw colors."[/QUOTE]</p><p><br /></p>
