How the Collapse of the Roman Empire made the creation of a wide variety of glass styles compared to the glass that was produced in the Empire

Ancient Rome made the type of glass we use today the thin, clear glass but when Rome fell the towns and villages had to start living without the help of the Roman Empire. One continuous thing Rome distributed was glass and when Rome fell villages had to make their own glass. They often recycled glass from older buildings but they still had to make their own glass. Since they did not have the same ingredients Rome had the glass they made was different. It was a dark green or brown color and much thicker. This type of glass is called forest glass. Once the villages realized they could make colored glass they started making stain glass windows on churches and such. This shows how much Rome had really paused creativity by doing everything for every one.
