MANUFACTURING & QUALITY CONTROL OF THE FULL GLASS BALL
Photography with a glass ball benefits above all from the effect that it captures the surroundings mirror-inverted as a 180-degree view in the smallest of spaces. Now with the camera lens (ideal: 2.8 / focal length 24 mm - 35 mm) Focus on the subject in the glass sphere and work with a shallow depth of field, but still let the background flow artistically into the picture.
For all of this to be possible, it must Glass of the highest quality and without inclusions are manufactured. Our special ones take care of that quality controls and the transparent manufacturing process in which the balls are checked several times during production for material defects, inclusions and cracks.
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 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 inspection of raw material for cracks & inclusions. All full glass balls that are of perfect quality now go to the grinding and polishing, until they get their absolutely flawless and round shape. Then the next check for air inclusions and other defects. If a defect is noticed here, the glass ball is sorted out. Now the final fine-tuning with a high-speed polishing machine. After a certain time, the balls are completely transparent and have a perfect surface quality. The final quality control now follows the perfect end result of every glass ball. This is the only way to ensure that the glass ball does not later negatively influence the refraction of light, or that inclusions and scratches appear as disruptive elements in your mirrored motif.
