Do you know, how workers ing the glass factories refreshed theirselves in hot summer days? They put glass balls into the box and than put their legs into it.
Glass balls are not only for the playing, but htey have also big sense in the industry. These balls are named - technical balls. They are used in the production of paints, lacquers, where they are used as the milling medium or the filler. Technical balls are used also in chemical and pharmaceutical industry. They can fill spaces, isolate, jet the surface, be used as the gasket.... . We can meet them in rol-onech, ink cartridges, in valves.... Their usage depends only on the type of glass, which is used, size and the roundedness. The special position between technical balls have precision glass balls.
