Silk, always considered precious and noble from the beginning of time, was once privilege of Chinese emperors, members and ministers of their court. Throughout the centuries Chinese silk became so important as to develop an entire economic system around it. As a result, in 1000 A.C., China began exporting to the West. According to Chinese tradition it was an emperor’s wife in 3000 B.C. to introduced silkworm harvesting to China: tradition narrates that Empress His Ling Shih harvested a large amount of silkworms and one day, as she was drinking hot tea under a mulberry tree, a cocoon fell into her cup. The warmth of the tea allowed her to unravel the cocoon and a thread, almost a kilometer long, came out. From that point on, silkworm farming came about. The silkworms were fed on mulberry leaves.
