Re: [APD] tempered glass

Well, the iron makes the glass green. So if the iron isn't there, the glass 
does not have the green coloration. From this we can deduce that iron makes 
things green, so if we want red plants, we need to have no iron. This does 
not explain why Vulcan blood, which is copper based, is green, and human 
iron-based blood is red.
