Incendiary mixture: Barium nitrate, 30.4 percent; paraffin, 19.4 percent; magnesium, 11.3 percent; aluminum, 11.1 percent; rosin, 10.9 percent; ferrosoferric oxide, 9.1 per-cent; nitrocellulose, 4.4 percent; gritty siliceous material, 2.6 percent.

Description: This incendiary bar is specifically designed to resemble a bar of "Ivory" soap. The word "Ivory" is stamped on one side and "Proctor and Gamble" on the other. The bar burns with an intense flame, but is easily extinguished by water. It is difficult to ignite.

No method of ignition has been found, but it is probable that some type of ignition device is inserted into the recess in the side of the bar.
