Abstract
An invention is provided for creating smoothed, heat-treated glass fragments. The invention includes placing a plurality of heat-treated glass fragments into a tumbling or vibrating apparatus. Each heat-treated glass fragment is formed from glass that has been heated to a temperature of at least 1000° Fahrenheit and rapidly cooled to a temperature below 700° Fahrenheit. The plurality of glass fragments are then tumbled or vibrated for a predetermined period of time such that surfaces of the heat-treated glass fragments are smoother than prior to tumbling. The glass fragments are thereafter removed from the tumbling apparatus, resulting in smoothed, heat-treated glass fragments that are suitable for direct handling without hand protection.
Claims4
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.
