<unk> s are mainly produced for use as fertilizers in agriculture because of their high solubility and biodegradability. The main<unk>  fertilizers are ammonium, sodium, potassium, calcium, and magnesium salts. Several million kilograms are produced annually for this purpose. The second major application of<unk> s is as oxidizing agents, most notably in explosives where the rapid oxidation of carbon compounds liberates large volumes of gases (see gunpowder for an example). Sodium<unk>  is used to remove air bubbles from molten glass and some ceramics. Mixtures of the molten salt are used to harden some metals.<unk>  was also used as a film stock through nitrocellulose. Due to its high combustibility, the studios swapped to acetate safety film in 1950.
