Galena - PbS         Pair of small teaching hand specimens

Galena is a very common metallic sulfide. It often occurs in cubic crystals and has good cubic cleavage. It is practically the only source of lead, which is used in huge amounts in storage batteries and in shielding from radioactivity. Its name is the Latin name for lead ore.

Galena is easily identified by students by its density, metallic luster and its cubic cleavage.

Oddly, this galena came all the way from Morocco. We got a good deal on a small supply. This is a mineral that is expensive to ship, and it is often offered at a price that makes classroom specimens uneconomical. These are offered as a pair of small hand specimens.
