1. Smoothed, heat-treated glass fragments prepared by a process comprising:
breaking heat-treated glass plates has a surface compression of at least 3,500 pounds-force per square inch (PSI) creating sharp heat-treated glass fragments thereby;
the heat-treated glass fragments having sharp edges and corners;
placing a plurality of heat-treated glass fragments having sharp edges and corners into a tumbling apparatus;
tumbling the plurality of heat-treated glass fragments for a predetermined period of time such that the sharp edges and corners of the heat-treated glass fragments become slightly rounded and are smoother allowing for safe handling than prior to tumbling; and
removing the plurality of slightly smoothed shaped glass fragments from the tumbling apparatus, the slightly smoothed and shaped glass fragments having slightly rounded, bead-like shapes.
