Blue-Green transparent Glass blown vessel from En Gedi, Israel. Glassblowing began in the Syrio-Palestine/Canaanite region around 50 BCE. Even after Phoenician and Judean glassmakers were brought to Rome, Syro-Palestine remained the center for the highest quality glass. The technique was faster, less labor intensive, easier to color and allowed larger transparent vessels to be made on a large scale to the point they were affordable for the non-elite. Israel 50 AD-150 AD Roman period.
