What is a sandblaster?
A sandblaster is a machine that uses compressed air to propel particles of abrasive. The high energy of these abrasive particles will chip away tiny, precise bits of glass from the surface of the glass being blasted. Although the name of the tool implies that sand is used as the abrasive, sand is not the best abrasive for use on glass. Selecting and Purchasing Sandblasting Systems There are two basic sandblaster setups: the pressure pot blaster, and the siphon blaster, and there are pros and cons to each. Pressure pot systems have a separate reservoir to hold the blasting media. They are generally felt to be preferable because they blast faster, use compressed air more efficiently, and can be used at lower pressures – which will put less strain on your compressor. However, they require that the abrasive be periodically removed from the blast cabinet and returned to the reservoir. Siphon systems are initially more economical and allow continuous blasting without having to recycle the ab
