<p>[QUOTE=&quot;AgCuAu, post: 1823938, member: 58871&quot;]do we say brass, for example, tarnishes or tones? i&#039;m not sure if brass tarnishes( the term I use with brass in general) easily but it appears to in my experience and that layer of tarnish (oxide was it? which protects the metal from further deterioration) can be cleaned off (which I&#039;ve read elsewhere wouldn&#039;t be beneficial since the layer of oxide is supposed to be beneficial for example on aluminum) with polish or something else. the brass in question is simply left alone but to be in constant contact with the air and fluctuating humidity which are natural events on a daily basis. Could we say a metal tones when coming into extended contact with such natural events then?</p><p>&nbsp;</p><p>in my understanding as a side note, toning is not a natural occurrence(in the sense that it&#039;d have to be subject to some sort of process contrary to normal circumstances), unlike tarnishing which to my understanding is through oxidation which is a normal process owing to our atmosphere.</p><p>&nbsp;</p><p>Just a thought, hope not to fan the flames or anything.[/QUOTE]</p><p><br /></p>
