Lead


Lead Brick
Source:  My Lab
Purity:  99%

This sample demonstrates one of the many uses of lead - it's really heavy!  With a density of around 13.1g/cm3, it's almost twice as dense as steel, and we use this brick of lead as a weight for holding things down.
Bucket O' Lead Pellets
Source:  My Lab, My Thesis Project!
Purity:  99.99%

These lead pellets come from my personal stock of lead for my Lead-Bismuth corrosion experiments for my thesis.  Since I only have a scant 225 pounds left, I only took a picture of a bucket full before I stuck it in the furnace with Bismuth to be melted into Lead-Bismuth Eutectic.  The pellets are coated in an oxide, which forms readily in air.
