Silver Fluid
For silvering brass and copper articles of every
description
Take an ounce of precipitated Silver to half an ounce of
Cyanate of Potash and quarter of an ounce of Hyper Sulphate of Soda.
Put all into a quart of water, add a little whitening and shake before
using. Apply with a soft rag. This knowledge alone is worth one hundred
dollars.
