INFORMATION has recently been obtained from Germany regarding a process used there for heat treatment of optical components made of sodium chloride.
Dry particles of sodium chloride, in the size range of 0.5 to 20 μ in diameter, were introduced from an aircraft into moist air at altitudes of 400–500 m over the sea near the island of Hawaii.
Sodium and chlorine react vigorously when heated, giving an orange flame and clouds of white sodium chloride.
