In the video, a man is seen holding a piece of glass with a long metal rod. He then places the glass on a metal table and uses the rod to spin the glass. As he spins the glass, it begins to take on a different shape. The man continues to spin the glass, and it becomes more and more rounded. The glass is then placed into a furnace, where it is heated until it becomes a molten liquid. The man then takes the glass out of the furnace and begins to shape it with his hands. The glass is then placed back into the furnace, where it is heated until it becomes a solid piece once again. The man then takes the glass out of the furnace and begins to shape it with his hands. Throughout the video, the man is seen wearing protective gear, including gloves and safety glasses.
