Abstract
Experiments were conducted on the physical and chemical properties of U. S. made salt such as the color, the shape of particles, the distribution of particle size, the apparent specific gravity, the angle of repose, the velocity of moisture adsorption and solution, and the chemical composition. The following are the results obtained:
1) In the U. S. A., there are many kinds of salts each of which is suited to its own purpose. They are found to greatly differ in physical and chemical properties from the another according to the purpose.
2) U. S. made table salt is extremely good in the free-flowing quality as compared with domestic salt, and sodium silico alminate is found to have been used in it as an additive agent.
3) In general, U. S. made salt contains very small amount of calcium and magnesium salts, and therefore the content of sodium chloride is greater than that of the domestic salt.
