The history of glass windows is actually more interesting and older than you may think it is. The production of glass has been occurring naturally for millions of years but it is the discovery of manufactured glass that leads us on this exciting journey. The first instance of glass being made by mankind can be credited to the Mesopotamians who manufactured their own glass as early as 3500 B. C. The people of Mesopotamia used this man-made glass for simple uses, such as decorating pots or other vessels.
The first actual use of glass for windows, certainly in Britain, can be found as far back as the 1st Century A. D. At this time the Romans used glass for windows, mosaics and to decorate pottery. The rise of the glass window came with the building or churches and places of worship. Many of the early fragments of glass windows are coloured, suggesting they were stained-glass windows from churches and monasteries.
It was not until the 13th century that the manufacture of glass for windows really took off. The skill of producing sheet glass had been mastered by the Germans in the 11th century and perfected by the Venetians by the 13th century.
During the 14th century, the French managed to perfect the art of blown plate glass (this is where it is hand blown then grinded and polished to look smooth). They also perfected Crown glass which was hand-blown glass that was flattened completely. The French were reluctant to divulge their manufacturing secrets before the 17th century, resulting in Crown glass and blown plate glass not being manufactured anywhere else until this time. Until the 19th century the world saw the rise in popularity of these two types of glass for making windows.
Flat sheet glass became popular after this time, which is the type that is used in many of the old-style sash windows. After the First World War and with the invention of float glass in 1959 by Sir Alistair Pilkington, the old types of window glass were pretty much made redundant.
The history of glass windows is a fascinating story and is something that is destined to go on and on. Indeed, we have different types of glass being developed frequently, such as toughened glass and safety glass that are often used in many of the double glazing units found in modern homes. The development of glass windows is always evolving, with the newest form being Smart glass, which changes the light intensity of the window with just the flick of a button.
