Sparklers are one of the many types of fireworks and the only one that can be safely lit indoors. Their construction is very simple - they consist of metal wire covered with a mix of barium nitrate and iron. It is the iron filings that are responsible for the intense sparking effect.

Sparklers are most popular during Christmas time and New Year's Eve, as they are enjoyed not only by the youngest ones. They are also an attraction during New Year's Eve balls. More and more often they are also chosen as an attraction for birthday parties or wedding receptions. Experienced photographers use them to create amazing photos, which are a unique souvenir from the wedding day.


Where did the name of sparklers come from?

Sparklers, while burning, produce sparks that don't burn and do not set fire to what they fall on. It is from them that the name was taken. The only "dangerous" element can be a wire, which reaches a very high temperature and, if kept in the wrong place, can burn the thing it touches.


How do sparklers work?

About 3/4 of the wire is covered with a mixture of barium nitrate (or potassium nitrate), iron and adhesive. The high temperature causes the oxidant to transfer oxygen to metal particles so that the metal reaches a temperature of up to 1,300 degrees Celsius. The chemical reaction that occurs, contributes to the formation of rapidly extinguishing sparks.


Sparklers history

According to the available information, sparklers were invented around the V-VI century AD. The prototype of this kind of fireworks was used not for light effects - it was supposed to be used for fighting. Later research led to the invention of a Greek (Byzantine) fire, which was a flammable substance, now regarded as a prototype of napalm.

We owe the modern form of sparklers and fireworks to the Chinese, who have reached a master level in creating unique light effects.


Safety during lighting sparklers

Although sparklers are one of the safer types of fireworks, it is important to know that touching the hot wire and burning material can cause burns. The sparks themselves are safe - they do not burn or ignite the things they fall on.

However, an important issue is storing sparklers. Improper conditions result in damage to the mass, which in turn has a defective effect on the working of the products. The most negative effect on sparklers has moisture, which can prevent the mass from igniting.

There are several lengths and types of sparklers in INS FireWorks. Low price and safety of usage make sparklers one of the most frequently chosen types of fireworks.
