Our molded glass beads are made from superior quality hardened soda lime glass.  They are processed with state of the art molding technology.  This process enables an exact forming of the beads especially with diameters over 4.0 mm.  These beads offer excellent roundness in sizes up to 25 mm.  They are shiny and smooth, with a low proportion of air bubbles, and a high degree of purity.

These have similar uses to the GSR beads, but are available in larger size range and have a tighter tolerance than the GSR.
