Silk
Silk is a natural protein fibre, some forms of which can be woven into textiles. The protein fibre of silk is composed mainly of fibroin and produced by certain insect larvae to form cocoons. The best-known type of silk is obtained from the cocoons of the larvae of the mulberry silkworm Bombyx mori reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors.

Famous quotes containing the word silk:
“Why silk is soft and the stone wounds
The child shall question all his days,
Why night-time rain and the breast’s blood
Both quench his thirst he’ll have a black reply.”

“Her fortune, too, lies there,
Converted into cool hard steel
And right red velvet lining;
While over her tan impassivity
Shot silk is shining.”

“Come, let me sing into your ear;
Those dancing days are gone,
All that silk and satin gear;
Crouch upon a stone,
Wrapping that foul body up
In as foul a rag....”
