How to Make Your Own Gunpowder

Gunpowder is an explosive mixture of sulfur, saltpeter (potassium nitrate), and charcoal to produce explosives. It was the original form of gunpowder, and it is still in use today in cannons, handguns, and rocket fuel. 

One of the most essential ingredients, saltpeter, is difficult to come by for the majority of the population. It can be obtained from soil that contains high concentrations of organic material, but it is often more convenient to simply purchase potassium nitrate from a store. 

The absence of potassium nitrate does not preclude the production of gunpowder using other ingredients. 

On the other hand, making your own gunpowder can be better if you have access to the right ingredients. Here are some step-by-step instructions for making your own gunpowder at home.

How to Make Your Own Gunpowder

1. What is Gunpowder

It is a black, powdery substance that was historically used in the manufacture of firearms. It is composed of the minerals saltpeter, charcoal, and sulfur. 

Saltpeter is the primary component of gunpowder, and it is this ingredient that causes the explosion. The charcoal serves as a fuel source, and the sulfur aids in igniting the gunpowder.

In the presence of a spark or flame, these three components become explosive and explode into smaller pieces due to the resulting explosion. 

To fertilize the soil, saltpeter has been used for thousands of years. It is found naturally on the earth and is harvested by digging around limestone deposits or bat caves, where it can be found.

2. The Ingredients for Gunpowder

The ingredients for gunpowder are straightforward: Saltpeter, Sulfur, and Charcoal. These can be found at most local hardware stores. Saltpeter is a compound made of potassium nitrate and has been used for centuries in different applications such as fireworks and fertilizers. 

Sulfur is a yellow mineral commonly used in fertilizers and easily found. Charcoal is made from burning wood with the absence of oxygen, leaving behind carbon with a porous structure that allows it to burn very efficiently. 

It is commonly used as fuel because it does not produce any off flavors when burned at low temperatures, such as mesquite or hickory woods. 

The goal when making gunpowder is to create a compound that will produce as much heat and light as possible when ignited. 

To make your gunpowder, you will need the following: 

  • Saltpeter- 100 grams 
  • Sulfur- 100 grams 
  • Charcoal- 200 grams

3. Instructions on How to Make Your Own Gunpowder

Start by mixing 100 grams of Saltpeter, 100 grams of Sulfur, and 200 grams of Charcoal, stirring occasionally. Strain out the liquid and dry in sunlight or low oven heat (~200 degrees F) until it is completely dehydrated into powder form. 

It’s now ready to use! Be sure that you keep this material away from open flame sources and any flammable objects such as paper towels and rags because these materials can catch fire if they come close enough to gunpowder residue on surfaces, so be careful during storage or transportation after creation. 

Put the finished product inside an airtight container like Tupperware and store somewhere cool where there isn’t too much humidity. 

If you want to make your gunpowder, the quality of the ingredients will affect the quality of the powder. Make sure you use fresh, high-quality materials. You’ll need a mortar and pestle or some other way to grind the ingredients into a powder form.

4. Safety Precautions

Safety precautions for this project are essential. You need to be aware of the dangers of making homemade gunpowder and handling it, and storing it for future use. First, make sure that there is nothing flammable near your work area that could ignite during the process later on down the road. 

Second, always wear safety glasses because if lumps fly up into your eye – well, let’s just say things won’t end up too pretty! Third, put out all cigarettes before starting to avoid fires from stray ashes.

Fourth, keep out of reach of children. Precautions are always a good idea when dealing with chemicals or powders. Safety always comes first!

5. Tips and Tricks

Make sure you are using the right ingredients. This is not a recipe for just any old powder! Be precise in your measurements. Gunpowder is incredibly sensitive to changes in weight or volume, so make sure you measure everything out accurately. Grind the ingredients as finely as possible. 

The finer the powder, the more powerful it will be. Store your gunpowder in an airtight container and keep it away from moisture. Damp conditions can cause premature detonation. Finally, use caution when handling black powder! It can be extremely dangerous if mishandled. 

Always take proper safety precautions when working with this substance—There’s a bunch of different gunpowder recipes out there, with wildly varying degrees of power and explosiveness. Exploring with gunpowder can be a fun hobby, but it requires patience and caution.

Frequently Asked Questions

How do you measure out ingredients for making gunpowder?

Saltpeter, charcoal, and sulfur are mixed to make gunpowder. The most common blend is 100 grams of Saltpeter, 100 grams of Sulfur, and 200 grams of Charcoal per batch. Weight-based proportions If you prefer, you can weigh or measure the ingredients. If using weight, use a gram scale. Mix all ingredients in a bowl. Pour all ingredients into a quart jar and mix well.

Is there a substitute for gunpowder in fireworks?

Gunpowder is required for fireworks. Gunpowder is the only thing that can produce the same effects. Black powder is made from potassium nitrate, sulfur, and charcoal. To get the best results, use 100 grams of Saltpeter, 100 grams of Sulfur, and 200 grams of Charcoal.

Why is it better to make your own gunpowder?

It is better to make your gun powder because it gives the user a sense of power and control over their ammunition. However, making your own also allows you to experiment with different recipes and find one that works best for you. No matter the reason behind making your own, this guide will help walk you through how to do so easily without any previous experience in chemistry or pyrotechnics. 


Now that you’ve made your gunpowder make sure you remain extremely careful! It’s dangerous stuff, though. You should always handle black powder with care and store it in a safe place, away from children and pets. 

When you are done using your gunpowder, clean up any messes made. Be especially careful not to leave any behind as it can be hazardous.
