Glass Beads have technical applications in sectors as varied as:

Leading-edge or traditional technology industries (cleaning and finishing of surface by controlled shot-blasting)
Horizontal road markings (reflexivity of road surface markings so as to make them visible at night)
Conservation of historic buildings (cleaning of stone facades by dry projection)
Industrial site fire-fighting (multi-purpose extinguisher powder)
Manufacture of glass beads, with diameters ranging from a few microns to several millimeters, entails very high-precision processing
