    From the History of Glass: the Moon and the Cylinder

    At the end of the medieval period, the “lunar” method of manufacturing sheet glass began to be widely used in Europe. It was also based on the blowing method. With this method, at first the ball was blown, then it was flattened, the axis was soldered to its bottom, and the workpiece was cut off near the blowing tube. The result was a semblance of a vase with a soldered axle leg. The red-hot “vase” rotated with great speed around the axis and, under the action of centrifugal force, turned into a flat disk. The thickness of such a disk was 2–3 mm, and the diameter reached 1.5 m. Further, the disk was separated from the axis and annealed. Such glass was smooth and transparent. Its characteristic feature is the presence in the center of the disc of a bulge, which experts call the "navel."

     The lunar mode of production made sheet glass available to the population. However, another more sophisticated method came in to replace the lunar mode already at the beginning of the XVIII century. This new method has been used throughout the world for almost two centuries. In essence, this was an improvement of the medieval method of blowing, which resulted in a rather large cylinder. Its mass reached 15 - 20 kg and from it, as a result, glass sheets with an area of ​​up to 2 - 2.5 m² were obtained.

    This method allowed to obtain window glass of good quality and relatively inexpensive for the general population. Thus, the problem of a bright and warm dwelling was resolved only in the XVIII century. This was achieved by the work of many generations of glassmakers for two millennia.
