Chinese Silk

a silkworm spins all its silk till its death and a candle won't stop its tears until it is fully burnt." this tang poem accurately describes the property of the silkworm. despite technological development, a silkworm can only produce a certain amount of silk---1000 meters (3280feet) in its lifespan of 28 days. the rarity of the raw material is the deciding factor of both the value and the mystery of silk.

history of silk

legend has it that in ancient times, lei zu, the wife of huang di , taught people how to raise silkworms and how to extract the silk.

the warring states period, the beginning of feudalist society in chinese history, witnessed a prosperous time. the development of productivity popularized silk and it was no longer a luxury just for aristocrats. the pattern, weaving, embroidery and dyeing skills were all improved as they were influenced by the free ideology of the time, while the silk designs had sense of a free and bold air about them.

the silk products excavated from mawangdui han tomb are proof of the advanced skill and artistry of silk at this time.

silk production peaked during the han dynasty when the manufactured goods were transported as far away as rome from chang'an (today's xian). the overland trade route was to become famously known as the silk road. however, there was also a marine silk road extending from xuwen, Guangdong or hepu, Guangxi to vietnam. an outward bound voyage lasting five months would arrive in vietnam; it would take another four months to reach thailand; while a further twenty days would carry the merchants on to burma. two months later they would arrive in india and sri lanka, from where the silk would be eventually transported to rome via the mediterranean. after such a long journey, the price of silk was equivalent to that of gold. legendary as it seems, tender silk connected china to the rest of the world.

during subsequent dynasties, professional designers created novel patterns and improved the machines.

the marine silk road took supremacy over the land silk road following the song dynasty extending the trade to southeast asia which became fully developed in the yuan dynasty. besides chinese exports, foreign businessmen also came to china to buy silk and china wares.

during the ming and qing dynasties silk was transported to europe and america from manila and this meant that china dominated the world's silk market until 1908.

chinese characters including the component "silk" have the intonation of silk or its implication of fine and deep. the richness of color, texture, strength and beauty of silk make it the means to imply something is fine and impeccable. a woman's raven hair is referred to as 'black silk' ; tender feelings are 'feelings of silk' and the chinese word for a lingering and emotive feeling contains the component of "silk", and even a flavor can be silky and smooth.
