Sandblasting
Sandblasting or bead blasting is a generic term for the process of smoothing, shaping and cleaning a hard surface by forcing solid particles across that surface at high speeds; the effect is similar to that of using sandpaper, but is faster and provides a more even finish with no problems at corners or crannies. Sandblasting can occur naturally, usually as a result of particles blown by wind causing aeolian erosion, or artificially, using compressed air.

Sandblasting equipment typically consists of a chamber in which sand and air are mixed. The mixture travels through a hand-held nozzle to direct the particles toward the surface or workpiece. Nozzles come in a variety of shapes, sizes, and materials. Tungsten carbide is the most popular nozzle liner material for mineral abrasives. Silicon carbide and boron carbide are more wear resistant and are for use with harder abrasives such as aluminum oxide. Inexpensive abrasive blasting systems and smaller cabinets use a ceramic nozzle.

Historically, the material used for artificial sandblasting was sand that had been sieved to a uniform size. In the early 1900s, it was initially assumed that
sharp-edged grains provided the best performance though this was later demonstrated to not be correct.

Other materials for sandblasting have been developed to be used instead of sand; for example, carborundum grit,steel shot and grit, copper slag, powdered slag, glass beads (bead blasting), metal pellets, dry ice, garnet[3], powdered abrasives of various grades, and even ground coconut shells, corncobs, walnut shells, and baking soda (sodablasting) have been used for specific applications and can produce distinct surface finishes. Some commercial grade blasters are specially designed to handle multiple blast abrasives. These blasters are commonly referred as multi-media blasters.
