|Etched crystal rod.|
This is one of three short zirconium rods that Ethan Currens etched in a mixture of acids. He used various different combinations of aqua regia, nitric acid, and concentrated hydrofluoric acid to reveal different aspects of the crystal surfaces of these three pieces. All were cut from the same original bar, yet they look surprisingly different as a result simply of different types of etching.
