The Power of the Worm
How Corticelli Silk is Made. Boston, ca. 1876.
Corticelli was a silk company located in Florence, Massachusetts. The company started in 1832 as a farm planted with 25 acres of mulberry trees, later served as an important commune for abolitionists like Sojourner Truth, and eventually became the Nonotuck Silk Company, one of the world’s largest producers of silk thread. This broadside for the company explains in great detail how silk is made from the cocoons of the silk worm. In truth, by 1876 when this sheet was printed, the firm was importing most of its raw materials directly from Japan.
