Nobel found that nitroglycerin was very stable after adsorption with diatomaceous earth, but how to detonate it was a problem. After many experiments and at the cost of blood, he finally found that mercury citrate could be used to detonate the diatomite adsorbed nitroglycerin. The mercury citrate is filled in the small tube to form the detonator.
