Glass and glassware manufacturing is one of the most significant industries globally. The wide variety of glass products, the exclusivity of certain types, and their constant and growing demand have made this industry essential to modern life
In 1867, Frederick Siemens introduced a groundbreaking technical innovation that revolutionized industrial glass production: the continuous tank furnace. Remarkably, these furnaces remain in use to this day
Later, in 1903, an American inventor named Michael Jay developed the first automatic glass bottle production machine, which is considered an engineering milestone. This machine operated on a suction-and-impact principle, whereby a portion of molten glass was drawn into a metal mold and automatically cut into shape
In 1925, engineers Ingle and Smith patented the IS machine, which employed the Blow and Blow method to produce glass bottles. This technique—still widely used today—involves first blowing a molten gob of glass into a preliminary mold to shape the body, then transferring it to a second mold for final forming, where the ring and final details are created by blowing again
During the second half of the 20th century, the introduction of electronic control systems significantly improved production efficiency and volume
More recently, advanced methods such as Narrow Neck Press and Blow (NNPB) have enabled the production of lighter glass containers. This innovation not only reduces material usage but also contributes to energy conservation and environmental sustainability
