When it comes to gunpowder, there are many different factors that will affect its shelf life. These include the type of gunpowder, the storage conditions, and even the type of container that it is stored in. With that said, here is a comprehensive guide on how to determine gunpowder shelf life.
What is Gunpowder Made Of?
Black powder is made of a mixture of charcoal, sulfur, and potassium nitrate. The charcoal is usually made from willow or other hardwoods. The sulfur is usually derived from brimstone, and the potassium nitrate is usually derived from saltpeter.
Smokeless powder is made of a mixture of Nitrocellulose and Nitroglycerin. Smokeless powder can be made by mixing nitrocellulose with small amounts of nitroglycerin and other additives in a solvent, such as acetone.
When these ingredients are combined, they create a substance that is very flammable and can be used to create explosive mixtures.
How Long Does Gunpowder Last?
The shelf life of gunpowder depends on a few different factors. These include the type of gunpowder, the storage conditions, and the type of container that it is stored in.
With that said, here is a breakdown of how long each type of gunpowder will last when stored under ideal conditions:
Black powder – Black powder is the oldest type of gunpowder. It is also the least stable of all the gunpowders. Black powder is a mixture that does not “go bad” over the course of time. If it gets wet you can dry it out, if it freezes it still works, heat does not phase it until it reaches ignition temp.
Smokeless powder – When properly stored, an unopened container of smokeless powder has an indefinite shelf life, but once it is opened, the stabilizers it contains begin to slowly but surely weaken. Even then it can still last for a very long time
How to Store Gunpowder
The best way to store gunpowder is in a cool, dry place. Gunpowder should never be stored in a humid or damp environment. The ideal storage temperature for gunpowder is between 40°F and 70°F (4°C and 21°C).
Gunpowder should always be stored in an airtight container. The container should be made of a material that will not react with the gunpowder. The best containers for storing gunpowder are made of glass, metal, or plastic. Never store gunpowder in a container that is made of paper or cardboard.
How to Dispose of Gunpowder
The best way to dispose of gunpowder is to take it to a local gun store. Most gun ranges or gun stores will have information or resources where you can safely dispose of gunpowder. You can also contact your local police department or fire department to see if they can help. Gunpowder should never be disposed of in a trash can, as this could result in a fire or explosion.
Conclusion
Determining the shelf life of gunpowder is a complex process that depends on a number of factors. These include the type of gunpowder, the storage conditions, and the manufacturing process. However, there are some general guidelines that can be followed. gunpowder should be stored in a cool, dry place, away from heat and direct sunlight. It should also be kept in an airtight container. Gunpowder should be inspected regularly for any signs of deterioration, such as changes in color or texture. If any changes are observed, the gunpowder should be tested before use.
