3DShiny crystals in pretty mini-flask.
This is a small (1/2" diameter) round mini-flask containing some very, very shiny silver crystals formed by slow electrodeposition. The flask is closed with a cork, which probably won't exclude oxygen well enough to completely prevent tarnishing, but we'll see. I'm going to seal the other similar silver crystals from the same source (see next sample) under argon and compare the rate of tarnishing.
