The glass bead blasting medium is made of glass sand crushed by glass blocks and flat glass, and then smelted at high temperature in an electric furnace. Depending on your application, glass bead blasting media can be a good substitute for silica sand. Although silica sand is still legal, it is becoming more standardized and is considered the source of various health problems including silicosis.
Sandblasting media is a common use for glass bead blasting. Glass bead blasting is very suitable for use in blasting cabinets, where the blasting medium can be recovered. It can effectively clean the surface without leaving too much sandblasted contours. This makes it an ideal choice for removing paint or coating on parts and for removing rust. If contours are required, blasting media such as steel grit or alumina may be required, because glass beads are usually not deformed during blasting.
