Harvesting and processing: Take naturally occurring saltpeter, dissolve it in hot water, filter it, and let it cool to precipitate crystals, commonly known as saltpeter. Wash and slice the radish again, put it in a pot with water and cook until it is completely dissolved. Add plain nitrate and cook until completely dissolved. Take out the filtered or clarified top layer and let it cool until crystals precipitate. After drying, it becomes saltpeter (100 pounds of saltpeter per square meter, 10-20 pounds of radish). There are also natural products of saltpeter, which are boiled, filtered, and cooled. The upper layer of crystals is called saltpeter, and the lower layer of crystals is called saltpeter.
