title: Sodium Chloride: Modification of Crystal Habit by Chemical Agents.
abstract: Microscopic investigation of drops of brine evaporating in air revealed crystal forms of sodium chloride other than the cube, when cysteine, creatinine, papain, monosodium glutamate, sodium hexametaphosphate, a combination of sodium hexametaphosphate and aluminum salt, or aluminon were added to the brine in small amounts. Some of these have a definite effect in parts per million concentration.
