Cotton-Velvet.

Manufacturer and builder 3, 1883

There is a substance called cotton-velvet made in China. It is very soft and durable. Generally it is dyed of a dark-blue color, in a solution of one part of indigo to thirteen parts of water having a small admixture of wine and lime. After the velvet has been allowed to soak in this solution for about half an hour, it is wrung out and dried in the sun. This process is repeated eleven times, and finally the texture is dampened carefully with a spray of slightly acidulated water.
