The city of Hebron is also known worldwide for its famous glass blowers and designers. Glass factories, where hand-blown glass products are made, have been a feature of the city since the Middle Ages. Here one may observe, from beginning to end, the fascinating process of glass-blowing. This traditional craft has been adapted for factory production methods. The royal blue glass of Hebron is perhaps the most recognizable in the Middle East, but glass blowers also create items in many other beautiful colors.
