Black Copying Ink Or Writing Fluid
Take two gallons of Rain Water,
and put into it Gum Arabic one-fourth pound, Brown Sugar one pound,
clean Copperas one-fourth pound, Powdered Nutgall three-fourths pound;
mix, and shake occasionally for ten days, and strain; if needed sooner
let it stand in an iron kettle until the strength is obtained. This ink
will stand the action of the atmosphere for centuries if required.
