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 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 aeolianerosion, or artificially, using compressed air. An artificial sandblasting process was patented by Benjamin Chew Tilghman on 18 October 1870. www.TriCoat.ca/
