Why is it said that the discovery of glass was revolutionary?

            Glass was accidentally discovered around 3000 BC by Middle Eastern nomads while camping on a lake-side.

            They found chips of glass in the soil, which were actually created by the chemical reaction between silica content in the soil, and sodium carbonate deposits from the waters of the lake during higher temperatures.

            The oldest-known glass artefacts of consistently high quality date back to approximately 1500 BC when Egyptians made hollow glass by forming a core from a bag of sand or a lump of clay, attaching it to a metal rod and then covering it in molten glass. When the glass cooled, the clay was removed.

            However, glass vessels and utensils came into being nearly three centuries later. A glass maker in Syria discovered that a blob of glass at the end of a tube could be blown into a vessel of almost any shape.
