Plan No. 502. Stove Polish That Enamels
To make an excellent stove polish that was really an enamel, a Colorado man prepared the following:
Mix two parts of black lead, 4 parts of copperas, and 2 parts of bone-black with water sufficient to form a creamy paste. The copperas produces a jet-black enamel, causing the black lead to adhere to the iron.
The cost of making this was very slight, and when people saw what a fine polish it made it was easily sold.
