Copper (CU)

You oxydate slowly

You change every time

Our chemical formula

Doesn't seem right

You polish things slowly

But after a while

Shiny's too shiny

And bright is too bright

You're copper baby

Yuu'll turn into green

If I don't take care

The glow will disappear

You're a bittersweet taste

In the back of my mouth

A viscious reaction

That's burning my mind
