Single-crystal button. This very unusual slug of single-crystal tungsten, which originated with work for the military in the former Soviet Union, was given to me by Philip Kapchenko of Kaistar R&D, source of many wonderful elements. I wrote a story about the visit where I received this object. Philip offers this information about it: It's a part of a modular Tungsten-Titanium target that was made like a honeycomb. Titanium played the role of wax and tungsten monocrystals the role of the honey. The incline indicates direction of evaporation: thinner end to center thicker end to edge.
