Extract of Logwood one ounce, Bicromate of Potash
one-quarter ounce. Pulverize and mix in a quart of soft hot water. This
makes a beautiful jet black ink, which will not spoil by freezing.
One-half gallon of soft water, one ounce Gum Arabic, one
ounce Brown Sugar, one ounce clean Copperas, three ounces powdered Nut
Gall. Mix and shake occasionally from 7 to 10 days and strain. The best
copying ink made.
