The given process illustrates the procedure for manufacturing glass containers.
Overall, there is a series of steps, beginning with heating the glass powder and finishing with the packaged and discarded glass.
At the beginning of the process, glass powder is put into a furnace to be burned at 105 degrees Celsius. Then the hot glass is placed into the first mold for being pressed by a pointy-tip instrument. Next the thick-walled container is brought into the second mold which has a rounded bottom. Following this, the air comes into this mold, allowing the container to expand naturally.
At this stage of the process, the glass containers are heated in a kiln at about 500 degrees Celsius. Then they are cooled down in a machine at 25 degrees Celsius. Finally, the finished containers are carefully inspected and categorized. The high quality glass is packaged, and the faulty one is rejected.
