PLAN No. 490. METAL POLISHING BLOCKS
Reading edition
These are made of precipitated chalk, 2 pounds; powdered tripoli, 1⁄2 pound; jewelers’ rouge, 1 ounce. Mix into a stiff paste, with 1 ounce of glycerine and a pint of water, previously mixed, and pour on just enough of the liquid to work the powders to the consistency of fresh dough. Then place in little wooden butter molds to shape them and set aside to dry, then force out and fill again. The blocks are used with a soft cloth and a few drops of water, which will give metal articles a fine polish. You can sell all you can make of these, and realize a profit on them that will surprise you.
