<p>[QUOTE=&quot;Cherryhill, post: 849323, member: 70&quot;]Hoping that others will follow,</p><p><br /></p><p>Many years ago I had an opportunity to discuss glass matters with a glass factory chemist. Among my questions was &quot;Does sugar in a batch of glass turn it amber because it caramelizes?&quot;&nbsp; He chuckled and said &quot;No. before the batch melted the sugar would have all burned up. Sugar is an organic compound. it adds carbon to the batch, interacting with the iron present in almost all glass, turning it to rust. Rust is what gives amber glass it&#039;s color.&quot;</p><p>Many years later, in a visit to the Viking factory in West Virginia, I noticed a batch cart, awaiting an empty pot. Lying on top of it were grains of oats. I asked one of the workers &quot;was that a batch of amber?&quot; He said &quot;Yes, How&#039;d you know?&quot; I pointed to the oats. Old glass workers were fond of relating going out in the street, (19th century) and bringing in a shovel full of horse manure for the amber batches.</p><p>And we wonder why there are so many colors of amber.</p><p><br /></p><p>This is too important to loose, it&#039;s never appeared in any books.[/QUOTE]</p><p><br /></p>
