At Hagley, the DuPont Company made blasting powder and gunpowder through three major phases: preparation, production, and packing. Preparation involved procuring the three ingredients, refining them to remove impurities, and measuring them for each batch of powder. Production involved mixing the ingredients together, pressing the mixed black powder to increase its force, sorting the powder grains into different sizes for different uses, and drying excess moisture in the powder. Packing involved pouring the finished powder into kegs or bags, storing it in a magazine, and shipping it to DuPont customers all over the country.
