When it comes to building a custom fireworks display, nothing beats the power and flexibility of mortar tubes and fuses. But with great firepower comes great responsibility. At Elevated Fireworks, your safety is our #1 priority—so we’ve put together this beginner-friendly guide to using mortar tubes and fuses the right way.


🧨 What Are Mortar Tubes?

Mortar tubes are sturdy cylinders (often made from fiberglass or HDPE) designed to launch aerial shells into the sky. They're essential for shooting pre-loaded shells or custom-fused shows.

Key Features:

  • Designed to handle the explosive lift charge of aerial shells
  • Must be used on a flat, stable surface or rack
  • Can be reused if undamaged (fiberglass or HDPE only)

🚫 Never use PVC as a mortar tube—it can shatter dangerously on impact.


🔥 What Are Firework Fuses?

Fuses are used to time and link your fireworks together for a coordinated display. There are several types:

  • Quick Fuse – Burns fast (in seconds)
  • Visco Fuse (Standard) – Burns at ~1 inch per second
  • Slow Fuse / Safety Fuse – Great for spacing out effects

These fuses help you chain multiple fireworks together safely and creatively.


🔧 How to Use Mortar Tubes Safely

  1. Use the right size tube for your shell (e.g., 1.75" shell = 1.91" ID tube)

  2. Inspect the tube for cracks or damage before each use

  3. Secure the tube in a solid wooden rack or bury it halfway in sand/dirt

  4. Never lean over the tube when lighting

  5. Always have water, sand, or a fire extinguisher nearby

💡 Pro Tip: Use a launch angle of 10–15° away from spectators, never toward them.


🔗 How to Fuse Shells Together

Want to build a mini show from multiple shells? Here’s how:

  1. Cut fuse pieces to your desired timing intervals

  2. Use tape or zip ties to attach the fuses to shell leaders or existing fuses

  3. Protect the joints with aluminum foil or waterproof fuse covers

  4. Test burn a fuse section to estimate timing before showtime

⚠️ Never rush fuse work—improper timing is a top cause of accidents.


👷♂️ Fuse + Tube Safety Tips

  • Only adults should handle mortar tubes and fusing
  • Always wear safety glasses and gloves
  • Label each tube or shell if you're coordinating timing
  • Keep spectators at least 150 feet away for 1.75" shells and above
