These grenades are made in the form of glass flasks. Model 1H is a single container; Model 2H includes an inner glass tube filled with a solution of calcium chloride. The body of each grenade is filled with titanium tetrachloride which vaporizes, upon contact with the air. The calcium chloride permits the second model to operate at low relative humidity, whereas the first model produces a thin fog unless the air is quite moist. Both models discharge upon impact with any hard object.
