Fuses

What is a pyrotechnic fuse?

A pyrotechnic fuse is a component used to transmit ignition to a selected pyrotechnic product or element. Depending on the type, fuses can burn at different speeds and be intended for different applications.

Therefore, the term “fireworks fuse” covers several solutions with different properties. When purchasing, it is worth checking above all the type of fuse, its intended use and the declared burning parameters.

What is a Visco fuse?

A Visco fuse is one of the most recognizable types of fuses used in pyrotechnics. It has a characteristic construction and is used in many ready-made pyrotechnic products as well as other applications intended by the manufacturer.

An important feature is its specific burning speed, which allows predicting how the fuse will behave under conditions consistent with its intended use. Exact parameters may vary between individual products, so the specifications of a particular fuse should be checked.

Are all pyrotechnic fuses the same?

No. Fuses can differ in burning speed, diameter, construction, resistance to external conditions and intended use. A slow-burning fuse and a fuse intended for rapid transmission of ignition serve different functions and should not be treated as interchangeable just because they look similar.

What should you pay attention to when choosing a fuse?

The most important thing is what the fuse is intended for. Pay attention to its type, declared burning speed, length and the manufacturer's usage information.

You should not choose a fuse solely based on its appearance or color. Products with a similar construction may have different parameters, so technical data for a specific product matter when working with pyrotechnics.

Does the burning speed of a fuse matter?

Yes. Burning speed is one of the basic parameters of a pyrotechnic fuse. It specifies how quickly ignition travels along the fuse and allows distinguishing products intended for different uses.

Keep in mind that the value provided by the manufacturer is a parameter of a specific product. The actual behavior of a fuse may also be affected by its condition and the conditions in which it is used.

How should pyrotechnic fuses be stored?

Fuses should be stored in accordance with the manufacturer's information, protecting them from moisture, damage and sources of ignition. Before use, check whether the fuse is not damaged, severely bent or damp.

Pyrotechnic fuse vs. igniter – are they the same?

No. A fuse and a pyrotechnic igniter serve different functions. A fuse transmits ignition through burning, whereas igniters — depending on the type — may allow initiation of the product, for example using an electrical system.

If you want to control effects using a device or firing system, also check the category of pyrotechnic igniters and firing systems.
