Scandium


Scandium Spectographic Foil
Source:  Found, Spectroscopy Lab Cleanout
Purity:  99.9%

This unopened Scandium foil has some greenish-yellow oxide formations visible.  Nevertheless, it is mint in box, and is a sample of one of the rarer elements around.  I hear that if it were more abundant we'd have tons more awesome space-age alloys due to its properties, but alas, there just isn't much of it on this planet that we know of.
