5g 99.95% Barium Metal order Distilled Crystalline Ampoule Element Sample

A 5g sample of Barium metal in the form of beautiful distilled crystals under argon.  Purity is 99.95%.  Barium metal is almost never encountered in this form and will remain shiny forever.  Photos just don't do this sample justice.   Even under argon this metal will still darken slightly forming colorful hues on the surface as can be seen in the photos. Please check my Etsy shop for more element samples. I have almost every collectible element available. Thanks for looking. order
