Glass beads are used in glass bead blasting. It's an effective, low abrasive media for surface cleaning. Delivery pressure can vary depending on the desired surface finish. It's not sand.
Sand blasting uses silica of varying grit size which is a much more aggressive surface cleaning media.
In both cases, can affect dimensions and thus not recommended for joints or bearing surfaces. Also not recommended if blast residue can't be totally removed.
