Alfred Nobel patented dynamite in 1867 in Great Britain and in 1868 in the United States.1
Dynamite was a significant advancement in the field of explosives, as it provided a much safer and more stable alternative to handling liquid nitroglycerin alone. Nobel achieved this by absorbing the nitroglycerin into kieselguhr, a porous siliceous earth, which created a solid material that was resistant to shock but could be reliably detonated using a blasting cap.231
