"Tiangong Kaiwu" says: "Saltpeter, its quality is changeable and has a wide range of uses." Saltpeter, that is, potassium nitrate, has many physical properties.
First, saltpeter is white or colorless crystalline, like ice crystals, crystal clear, shimmering under light, which is quite beautiful to look at. Its particles are usually fine, and mostly exist in nature in the form of powder or fine crystals.
Second, saltpeter is very soluble in water. When placed in water, it instantly melts like ice and snow, disappears into thin air, and the water liquid becomes clear and transparent. And during the dissolution process, it will absorb heat, causing the water temperature to drop, and the hand touches the outer wall of the container, which can feel a trace of coolness.
Third, saltpeter has a low melting point. When heated, saltpeter is easily melted into a liquid, just like ice in the warm sun, turning into a liquid. This property makes it important in some processes that require specific physical changes.
Fourth, saltpeter has a small density and is lighter than most common ores. When held in the hand, it feels light to the touch, in sharp contrast to heavy metal ores.
Saltpeter has unique physical properties and has been used in many fields in ancient times, such as alchemy, gunpowder preparation, etc., playing an important role.
