1500-300BC In these years, the earliest glass artifacts were found in Egypt. They were said to be made out of molds that were found in Egypt as well as Syria. The Roman Empire advanced in glass art during the same time period.	1-100AD The popularity of blown glass grew and spread to Babylon, where they developed a new technique of glassblowing. Glass cost rapidly declined and was finally available to all citizens.	12th Century Glass art started to become popular in Italy, and it became the center of the art itself. In Europe, glass art was being mainly created with colored glass for stained glass windows in the churches and gothic architecture of that time.
15th Century Angelo Barovier invented crystal clear, colorless glass. This development was utilized to make the glass telescope and microscope in the Netherlands.	1600-1620 France became a major power in the glass industry at this time. Haspar Lehman used a new technique of cutting rock to crystal glass. This time was also the introduction of coal furnaces in England.	1670-1700 “William of Orange” passed a law that lifted taxes on distilled spirits and encouraged development and expansion of blowing glass. “Polished Plate” glass was introduced to France at this time as well.
1745-1800 The first textbook on glass blowing was made, called “L’Arte Vetraria” which means “Art of Glass”, first published in Italy. The crystal glass production began during this time.	1827-1900 The glass pressing machine was invented in America. It was the first regenerative glass furnace, which rapidly replaced the old coal furnaces they used to use. This allowed continuous production of modern glass art.	Late 19th Century An automatic glass blowing machine was invented by Michael Owens. Glass science became more of a research kind of art. New techniques like “flat drawn sheet” were discovered and developed
20th Century Glass artists began to mainly work in studios, outside of the factory environment. Many own their own studios and galleries as well, and some levels can be learned through education.
