History of Smoke Grenades
The Evolution of Smoke Grenades
The concept of smoke grenades dates back to the 19th century, but they were first used extensively in military operations during World War I. Initially, these devices were simple and less effective. Over time, with advancements in chemistry and technology, smoke grenades became more reliable and efficient, with various colors and types available for different situations.

How Do Smoke Grenades Work?
Basic Mechanics of Smoke Grenades
A smoke grenade operates through the combustion of a pyrotechnic mixture inside the device. Once the grenade is ignited, the chemicals inside burn and produce thick, colored smoke. The exact composition of the smoke-generating compound depends on the desired color and effect, with various chemicals providing different hues.
Types of Smoke Generating Compounds
- Potassium Nitrate – Often used to produce white smoke.
- Calcium Carbonate – Provides red or orange smoke.
- Zinc Chloride – Used for green and blue smoke. These compounds are combined with a fuel, typically a sugar-based material, to create the smoke effect.
