Etched button 1. This is an ultra high purity vacuum e-beam melted zirconium button that has had its surface etched with acid to reveal the crystal structure. Kindly donated by Philip Kapchenko of Kaistar R&D, who was disappointed when I guessed right the first time what metal it was. You might think I'm good at guessing elements, but actually it was just luck: Those transition metals are really hard to tell apart without measuring the density.
