The glass is first melted into a long rectangle. The high temperatures make the glass soft and easy to shape . Then individual cuboids are cut out of this glass rectangle. Due to the previous melting process, these cuboids are still easy to shape and are now placed in a hydraulic press and thus brought into their round shape. Now it's on Cooling down to room temperature of approx. 20 degrees Celsius . In order to avoid imperfections such as surface irregularities and bubbles, the glass spheres are cooled down very slowly and temporarily stored. After cooling down takes place the first check of the raw material for cracks and inclusions .
