- By Formula pot


  • Refer procedure


Render common ley caustic, by boiling it at full strength on quicklime; then take the ley and boil it with as much whale oil foot as it will saponify (change to soap), pour off into molds, and, when cold, it is tolerably hard. Whale oil foot is the sediment produced in refining whale oil, and is worth two dollars per barrel.
