<p>[QUOTE=&quot;mrjason71, post: 2997646, member: 90347&quot;]You know...I am still wondering about this lol. I was Googling some more still trying to figure it out. I came across my own question and re-read it with fresh eyes. Such a hard question to ask--to convey.</p><p><br /></p><p>I wouldn&#039;t open this back up but for seeing a means to help me ask the question better in GDJMSP&#039;s last reply where he says. &quot;...darker shades of red are often still given the Red designation.&quot; This is what I want to know about. These darker shades of red. A coin is newly minted. It goes through these darker shades of red. It becomes brown. Does it become brown because of the same forces that darkened the red to &quot;darker shade of red&quot;? Is it all cupric oxide? Or are different kinds of oxide causing different colors: cuprous = &quot;darker shades of red&quot; and cupric = brown/black?</p><p><br /></p><p>Maybe I need to take a chem class <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie2" alt=";)" unselectable="on" unselectable="on" /></p><p><br /></p><p>&nbsp;Maybe this thought experiment would help. Imagine you want to watch a newly minted copper coin go through all these darker shades of red all the way until it is a common brown coin. Could you set up a single set of conditions that could accomplish this over time? Or would you need two different sets of conditions--one to go through the darker shades of red and then another to turn it brown? Is brown just the darkest shade of red?</p><p><br /></p><p>Probably just confused things more. My apologies for not knowing I simpler way of asking this. Dont hate me![/QUOTE]</p><p><br /></p>
