<p>[QUOTE=&quot;TallCakes, post: 254425, member: 107&quot;]this is when it may be confusing to insert lead crystal into an ABP discussion. APB didn&#039;t contain lead; the clarifying agent used in ABP was manganese. If in doubt try a black light UV test to ascertain glass content. This may be a selling point to revive ABP sales with the new &#039;green&#039; generation...</p><p>Here&#039;s an informative article on lead leaching in lead crystal; tho&#039; it doesn&#039;t seem to address long term analysis. I&#039;d question how long measurable lead levels may continue to leach from the glass surface. They need to test a long term storage, and then clean and refill to test for additional leaching. This should be done for several sequences of storage to determine if or when leaching falls off or ceases.</p><p><a href="http://www.thenibble.com/reviews/main/wine/lead-crystal.asp" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.thenibble.com/reviews/main/wine/lead-crystal.asp" rel="nofollow">http://www.thenibble.com/reviews/main/wine/lead-crystal.asp</a></p><p><br /></p><p>many may be familiar with black light testing methods for ABP:</p><p><a href="http://www.brilliantglass.com/black-light-testing/" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.brilliantglass.com/black-light-testing/" rel="nofollow">http://www.brilliantglass.com/black-light-testing/</a></p><p><br /></p><p>this may be of interest to some:</p><p><a href="http://www.currentseparations.com/issues/16-3/cs16-3a.pdf" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.currentseparations.com/issues/16-3/cs16-3a.pdf" rel="nofollow">http://www.currentseparations.com/issues/16-3/cs16-3a.pdf</a>[/QUOTE]</p><p><br /></p>
