25 Interesting Facts About Glass
Glass is practically everywhere – from common glass doors and windows, to the small, yet adorable glass figurines on your grandma’s shelf, to artistic houses and hotels made of glass.
And here, the The Window Boyz team will share with you a whopping 25 interesting facts about glass.
How is Glass Made?
Glass can be literally described as liquid sand. Extremely high temperatures (1700°C) melt the sand and all the minerals inside it and, after it cools down, we get glass.
Glass is not just manufactured, but can also exist in nature. It can be found inside volcanoes in the form of the natural stone Obsidian.
Today’s technology is able to control the glass making process and refine the end product to achieve different colours or maximum transparency.
History of Glass
Glass in the form of Obsidian has been documented to be used in prehistoric times when man started using spears.
Other evidence suggests that the first man-made glass piece was manufactured around 3000 BC. Syria, Egypt, and Mesopotamia were well-known glass-making hubs.
The first hollow glass container, on the other hand, was made in 1500 BC.
In the First Century, the Roman Empire developed the art of glassblowing. Of course, it wasn’t the refined transparent glass we have today and it was mostly in different colours.
Later, colourless glass became available not just to rich folk, but also to the common crowd. After the collapse of the Roman Empire, the knowledge of the art spread across Europe and the Middle East.
In 1291, the glass furnaces in Venice were shifted to the island of Murano as it was feared that the furnaces would set the city on fire.
By the 17th century, ordinary people in Europe could afford to use glass for their windows. This resulted in an improvement in their quality of life as it allowed them to lead a more hygienic and disease-free existence.
