What are Sparklers Made of? | Chemistry Behind Firecracker

Sparklers are fireworks you keep in your hands and watch while glowing flares. You must be curious about What are sparklers made of? Potassium nitrate is commonly employed as an oxidizer. Stay tuned, you are going to read about this topic in detail. 

Firecrackers burn slowly and give you a lot of time to swirl them with different atmospheric patterns. When sparklers burn, potassium chlorate decomposes to form potassium chloride and oxygen. Some fireworks are user-friendly, but they still burn a high atmosphere and give a tough time to kids to handle them. In that sense, they are unfortunately a significant cause of burn injuries if not handled with precautions. To avoid any inconvenience, it is recommended to read handling guides for sparklers.

This article is very informative for fireworks lovers, you are going to read about the process of fireworks production and what materials make them. As you already know what sparklers are, the next step to know must be how to make these firecrackers. 

What is the purpose of the popularity of firecrackers?

Fireworks are notably popular among kids. Young children use these firecrackers at bonfires, some joyful events, and on their country’s independence day. Fireworks are a source of expression for people at special events. They believe that firecrackers burn away the wrong vibe and deeds of that particular event and bring joy into their lives.

Fireworks were famous in old traditions, they show “symbolic emancipation.” 10,000 fireworks were used in events to represent light, intensity, love, and inventiveness. 

Composition of Basic Sparkler

Moving ahead to our discussion about what sparklers are made of, there are three things that are essential for sparkler production: a metal wire, an oxidizer, and a powder. To change the final product, other optional ingredients can add up to the combination. 

Metal Wire:

The metal wire makes the core of the firework just put into the composition as a glue that the metal can be covered in. Dextrin is a carbohydrate molecule that is made up of long chains of glucose units that are made by the breakdown of starch. It acts as a binder for the metals to a wire.

It enables the potassium perchlorate and powdered metal ions to stick to the wire due to its sticky property just like starch. In the manufacturing process, it also burns, generating heat that aids the breakdown of the perchlorate and improves metal burning. Sparks from the fireworks don’t circulate a little since the metal pieces burn up very rapidly and are quite small. However, direct contact with the firework as it is ejecting burning particles could result in a severe burn. 

Oxidizing Agent:

The second agent in the composition of fireworks production is an oxidizer, which is a metal oxide, chlorate, or perchlorate, including potassium nitrate that acts as a prevalent instance and plays a crucial part. These oxidizer molecules break down when burned, and they all release oxygen as the end product.

Particles of the blazing metal powder expel from the sparkler by the generation of fumes even during a breakdown event. As electrons keep burning and combine with oxygen to form metal oxides, this produces the glowing pigment.

Metallic Powder

Another essential ingredient is powder metals that play a role in the color management of glowing sparks. The iron part gives orange sparks whereas Ferrous and iron alloys give yellow and gold mixture glows.  Aluminum, magnesium, and titanium all create sparks that are almost perfectly white. If you want to add more colors, you can add up extra chemical colorants. These resemble the dyes seen in large pyrotechnics, salts of different metals that can add green, blue, and red to the display.

Additional Ingredients of Sparks Production

Two gunpowder components Sulfur and Chloride may act in flame burning. They act as reducing agents and consume the oxygen formed by the oxidizers, which can change how long the firework burns. It only acts as a reducing agent in the process. The utilization of extra fuels can also modify the temperature of the blazing glow stick, which could also reach nearly around 1000 and 1600 C. 

How do Firecrackers Work?

There are many types of fireworks, such as black snakes, firecrackers, and sparklers. All of them work differently. A regular firecracker burns and produces a noisy explosion. Whereas, the black snake makes ash fumes. On the other hand, Sparklers burn for a long time and generate high sparks in the atmosphere. 

A chemical mixture glues on a stick or a wire to give sparkles. This mixture is useful for coating a wire or tube. When this wet mixture is dried you can use it for making sparklers. As we have discussed above, aluminum, iron, oxides, zinc, and magnesium are some ingredients that generate sparks. 

The ratio of the fuels and oxygen causes the sparkler to burn steadily as opposed to bursting like a firecracker. The firework burns gradually from the other end after being lit at one end. That’s how sparklers work. 

Safety Precautions with Chemical Mixture: 

The blazing flame agent constitutes burning risks as well. Sparking chemicals are not very harmful if you handle them with safety precautions. According to National Council, a huge amount of fireworks-related injuries are reported due to ignorance of safety protocols. Be careful while using them in any way that could result in the ingestion of the ash, such as burning them on cakes like candles. The consumer product safety commission also checks products before allowing them.

Quality Considerations:

You always consider important factors and do complete research before buying any product. Same works from the quality perspective of buying the best quality sparklers. There are multiple factors you need to consider before buying them such as:

  • Production material.
  • Burning duration.
  • Brand Reputation. 

Avoiding low-quality Firecrackers:

A lot of things not to consider when evaluating a sparkler’s value. These aspects essentially operate as deterrents that prevent you from discovering the best net bargain. 

  • Price.
  • Packing.

Final Remarks

Consequently, what sparklers are made of, you are now well aware of what components are required for their production. It is also recommended not to re-light sparklers as they can be dangerous fireworks. Hence, you know the chemistry behind sparks whenever you plan to have a festive night or celebration. For some people, it’s a very special day for them to celebrate their every joy so be aware of buying any fireworks, keeping safety measures in mind.
