Haloxyline, or Bleckman's Powder, is an explosive compound of sawdust freed from resinous matter, with saltpetre, charcoal, and sometimes also yellow prussiate (ferrocyanide) of potash. The substances are mixed, slightly moistened with water, crushed, ground, pressed to a cake, and then grained like gunpowder. The ordinary proportions are: sawdust, 9 parts; charcoal, 3 to 5 parts; saltpetre, 45 parts. The ferrocyanide is added if very quick explosion be desired.
