Zinc Galvanizing: About one-half of the zinc that is produced is used in zinc galvanizing, which is the process of adding thin layers of zinc to iron or steel to prevent rusting. This photo shows the surface of a sheet of metal with a galvanized zinc coating. The different color domains across the sheet are caused by zinc crystals in different crystallographic orientations reflecting different amounts of light.

frac sand
Frac Sand: Close-up view of frac sand (on the right) and a typical sand of similar grain size (on the left). Notice how the frac sand has a more uniform grain size, nicely rounded grain shapes, and a uniform composition. It is also a very tough material that can resist compressive forces of up to several tons per square inch. Grains in this image are about 0.50 millimeter in size.

Stone meteorite with fusion crust: This 307.1-gram stone meteorite fell as part of a shower on October 16, 2006 in Mauretania. It is an ordinary chondrite (H5) and an excellent example of a complete fusion crusted stone. This specimen was picked up immediately after the fall. Note the very fresh, rich black fusion crust which is reminiscent of a charcoal briquette. Fusion crust is thin and fragile and will weather away over time, so a recently fallen stone will exhibit a dark black crust with no weathering or rust stains.
