So what you’re saying is, they had transparent aluminum?

  I think he's suggesting that our modern view of glass as clear is probably not what Roman's would have pictured first. They would have been far more used to non transparent glass, and might have mistaken aluminum for glass considering it's lightness

    Aluminium is the least likely metal given other information presented here.
