BLENDKORPER 2H SMOKE GRENADE

Blendkorper 2 H Used by the Germans as a smoke screen before attaching mines to oncoming Tank tracks among other uses.
The grenade consists of a pear-shaped, glass outer flask, resembling a large electric light bulb, almost filled with a brown liquid. Inside is a long tube filled with a clear liquid; both are capped with a sulphur and plaster of Paris cement. The total weight is slightly over seven ounces.

The outer flask is a pear-shaped glass bulb, 2-1/2 inches in diameter at the widest point, 3-15/16 inches in height to the neck, where it flares out 1/8 inch and forms a collar approximately 1 inch in height and 1-1/2 inch in diameter. This flask contains 8.75 ounces of titanium tetrachloride.

The inner glass tube is 3 7/8 inches long and 7/8 inch in diameter, resembling a test tube with the upper end sealed off; the weight is a little under an ounce. The upper end has a slight shoulder which rests on a rubber-like plastic washer; this washer in turn rests on the inside shoulder of the collar of the outer flask; thus, when the cementing material was poured, the inner tube was firmly sealed within the neck of the outer flask. The inner tube contains about 1.2 ounce of a 27 per cent solution of calcium chloride.

The smoke is produced by hydrolysis of titanium tetrachloride. The purpose of the inner tube of calcium chloride solution is to provide water to react with the titanium tetrachloride and produce an instantaneous smoke cloud in the desert or in cold areas, where the low humidity would cause a slow reaction. The calcium chloride is probably added to keep the water from freezing.
