Our wet milling and grinding glass beads contain NO FREE SILICA, and are made from superior quality hardened soda lime glass.  These glass beads are processed with state of the art rotating oven technology, developed originally in Europe. This process involves a unique method of rounding, washing, polishing and sieving, and results in a high quality solid glass sphere.  The process uses no hydro-fluoric acid, and thus our glass beads are not only environmentally friendly, they are shiny and uncontaminated.
