The Natsheh Handicrafts workshop is a family group that is carrying on this ancient tradition of mouth blown, hand-decorated glass that is passed down from generation to generation. Now using recycled coca-cola bottles and a steel pipe or kammasha, 1-1.5 meters long, the glasswork is blown at 1,000 degrees Celsius, then left for eight hours to cool. This tradition is threatened due to decrease in tourism, problems of export, and restrictions on movement of Palestinians.
