Men working for the manufacture of dynamite. A ship at a port. Men unloading sacks from the ship. Wood pulp is also used as a raw material in the manufacture of dynamite. The other material used is the nitrate of ammonia. Nitrate of soda is converted into nitric acid. It is dumped into huge retorts and is treated with sulphuric acid. Nitric acid vapors are condensed to a liquid in tiers of water-cooled glass pipes. Nitric acid is used to make nitroglycerin which is one of the most powerful explosives. Exterior of a building. Mixed nitric and sulphuric acid is run into a nitrator and refined glycerin is slowly added. The operator watches the thermometer as the chemical reaction releases an enormous amount of heat. An explosion can occur if the heat is not carefully controlled. He also watches the charge through a sight glass. Nitroglycerin and waste acids flow from the nitrator into a lead-lined trough which leads to a separator. The nitroglycerin rises to the top as the mixture settles. Then it is washed and led into storage tanks. It is transported to a dynamite mixing house in a rubber-lined and rubber-tired cart. Men working inside the building. A proper amount of the dry ingredients is poured into a mixing machine. Nitroglycerin is added to it. The mixture is further processed under revolving rubber-shod wheels.
