Dualin

Dualin is an explosive material [1] based on nitroglycerin and nitrogenized cellulose using sawdust or wood pulp.

Dualin is inferior to dynamite and more liable to explosion. Dualin was invented by the Prussian chemist Lieutenant Dittmar[2] in April 1869.[3]

Attacks with Dualin

In December 1909, Dougherty, and A. Rioux were killed by an explosion of Dualin, and W. Brennan, F. Lavally and E. Lalonde were injured. They were working in a shaft 40 feet deep. [4]
