Glass is one of the oldest forms of art. Just as everything else, at first, glass was made by nature. That was done in two different ways: one is when sand comes in contact with lightning and sometimes it fuses the sand into slim glass tubes called fulgurites(1). The other natural way glass was made is with volcanic eruptions, by fusing rocks and sand into what is called obsidian(2). Interesting enough, obsidian was used across the globe by many Stone Age societies. They would use this type of natural glass to produce sharp cutting tools. Due to the natural glass being so rare, the trade for it was very extensive. However, as suggested by archaeologists, the first true glass was made in coastal north Syria, Mesopotamia or Ancient Egypt.
