Invention of Glass , Explanation by ;@shahzadprincejee

Greetings to all my steemian friends! Hope 🤞 you will be fine . I am also fine by the grace of Allah Almighty. Last two days, I was thinking about any informative post . At last , I studied about the "invention of glass" . I am a student of Intermediate part-2 . I am not a business man so that I can't post about any business experience. Many of people do not know about the invention of the glass . Let's we start the article about the invention of glass.

Thousands of years ago , some fisherman camped for the night on a sandy beach . After they went to sleep , the hot coals from their campfier glowed for into the 🌃 night .
In the morning one of the men noticed a strange lump in the ashes . He had never seen a stone like it before . Puzzled, he picked it up and cleaned it off . As he turned it over in his hands , he saw that the 🌞 sunlight of early morning shine right through it . He was sure that it had not been on the beach the night before . Could the 🔥 fire some how have made this odd substance ?
Legends say that this may be the way that people first discovered glass . Glass is formed when sand is mixed with certain chemicals in a very hot 🔥 fire . Perhaps, by accident , all of these materials were mixed with sand on that beach . As time passed by , people found many uses for this new substance. Hundreds of years ago, 🏰 castles had only high , narrow openings in their cold stone walls. Because the wind and weather blew in threw them, they are called "winds eyes". This is where the English word "Window" came from . Wealthy people like kings began to use glass to cover these holes in the walls .
At that time, glass was hard to make and every expensive. Even kings could not afford glass for every window in their places and forts . Most of people used animal skin , pieces of cloth , or oiled paper . But these coverings did not let in much light , and no one could look out through them .

Over the years glassmaking improved a great deal . Today, glass is so clear like crystal that you can hardly tell it is there. 🏠 Houses can have many large windows.
The first lenses were used I glasses to help people see better . Then in 1609, an Italian scientist named "Galileo" put two glass lenses inside a tube .
Old glass is also used to pave to pave roads . Glass can be ground up and mixed with asphalt , a road-surfacing material. The ground up glass has no sharp edges. It makes a tough surface that engineers think may last longer than other materials .
In future , we may all be driving on glass roads and living in houses made of glass. Many other uses will also be found from this interesting material .
