The heat of the fire melted the niter, which mixed with the surrounding sand and flowed out as a stream of liquid glass! This story may or may not be true, but Syria was one of the original homes of glass making. And ancient Phoenician traders sold glassware all through the Mediterranean countries. Egypt was Another Country in which glass making was known at an early time. Glass beads and charms have been found in tombs which date back as far as 7000 B. C. , but these glass objects may have come from Syria. We know that about 1500 B. C. the Egyptians were making their own glass. The Egyptians mixed crushed quartz pebbles with the sand to change the color of the glass. They learned, too, that by adding cobalt, copper, or manganese to the mixture, they could produce glass with rich blue, green, or purple color. After 1200 B. C. the Egyptians learned to press glass into molds. But the blowpipe for blowing glass did not come into use until shortly before the beginning of the Christian Era. It was a Phoenician invention. The Romans were great glass makers, and even used glass in thin panes as a coating for walls. By the time of the Christian Era, glass was already being used for windowpanes!
Glass was likely discovered around 3500 BCE in Mesopotamia, when ancient craftsmen accidentally created it by subjecting a mixture of sand and other materials to high temperatures. The process of making glass was then refined over time, leading to the development of glassblowing around the 1st century BCE in the Roman Empire.
In the 9th century
Glass was first invented by the Sumerian Civilization around 3000 B.C. They prepared by mixing silica and sand in very hot forms. After cooling, what remained was glass. They also added various other chemicals to impart color to the glass.

I'm assuming the question is "when was glass first made by humans?"
The reason I'm making the question more specific is that glass has been around for millions of years as a volcanic product, namely obsidian or tachylite. Early humans prized this volcanic glass for knapping tools and weapons.
Man-made glass as far as can be traced with evidence is about 5000 years old and most likely is something that was developed out of the making of ceramic glazes. Glass as old as this has been found in Egypt and middle eastern countries.

There are many types of glass, with common categories including float glass, tempered glass, laminated glass, and stained glass. Each type has different properties and uses, such as for windows, tableware, or artistic purposes. The choice of glass type depends on factors such as strength, safety, and intended application.
A glass shop is commonly referred to as a glass showroom or a glass store where various glass products are sold and sometimes custom glass services are provided.

Natural glass (obsidian) has been used since the stone age. Manmade glass dates back nearly 5000 years and was probably discovered either by the ancient Egyptians, by people living in what is now Syria, or people living in Mesopotamia.
