Soap for Machine-Shop Men, Blacksmiths, Engineers, Printers, Scouring, etc.
Take 10 lbs. of hard, yellow soap; sal soda, 3 lbs.; borax and tallow, each 1 lb.; fresh slacked lime, as below; soft water, 3 gals. Directions—Put the water, soda and borax into the kettle, and when dissolved add the tallow and the soap, shaved fine; and when these are dissolved stir in as much freshly slacked, sifted lime as you can stir in well. The lime is to be sifted through a common kitchen sieve to avoid coarse lumps.
Remarks. —The lime thus stirred in greatly helps its scouring and cleansing properties; its roughness also helps greatly in washing hands covered with grease, ink, etc. It makes a good washing soap without the lime, but that adds more than half to its power of removing grease, ink, tar, etc., from the hands of machinists, where iron is worn into the grease on journals and by filing, etc. Without the lime it would make about 10 gals of splendid soft soap, if pre-. ferred in place of the hard; and in this case the tallow need not be put in.
