<p>[QUOTE=&quot;Just Carl, post: 498344, member: 4552&quot;]Most of this is erroneous. </p><p>1. Copper when tarnishing turns brown, not brightening. This is caused by combining with Oxygen forming CuO. This is nothing like a Brass finish. </p><p>2. Typing in all capatals is NOT rude at all. In fact most PROFESSI0NAL Mechanical and especially Electrical drawings are all in Capatals. Architect drawings on the other hand are usually all in small case and occationally slanted text. Of course this all depends on the Engineering firm and the clients. </p><p>3. Brass as a general rule is Copper with 1% Tin and 30% Zinc but this varies excessively pending on the final results required. </p><p>&nbsp;&nbsp; A. Hardness&nbsp;&nbsp; B. Flexability&nbsp; C. Polishability&nbsp; D. Melting differences.</p><p>4. The name changes to Bronze as you deminish the amount of Zinc and add elements such as Manganese, Aluminum and even Silicon.</p><p>&nbsp;</p><p>As I usually tell people. This is America. We speak American. Our history proves if we like a word, pharse or spelling, eventually we will adopt it. </p><p>The English can&#039;t force us to use their language although we still call it that in schools.[/QUOTE]</p><p><br /></p>
