FAQ
What is ferrocerium?
It is a metallic alloy (mainly cerium + lanthanum + iron) which, when scraped with a sharp steel edge, produces very hot sparks (over 3,000 °C) capable of igniting small dry combustibles.
Does ferrocerium work in rain/humidity?
Yes. Ferrocerium is unaffected by water—even when wet, it produces sparks as soon as it is scratched. This is one of its great advantages for survival in harsh conditions.
How to use it optimally?
1. Prepare a small nest of very dry tow (fine herbs, bark, cotton, plant fibers...).
2. Place the ferrocerium very close to the tow.
3. Scrape vigorously with a steel blade (forming an angle with the rod of approximately 45°) towards the tow.
4. As soon as the spark catches the tow, blow gently to make the flame grow.
Is there any coating to remove at first?
The black protective adhesive surrounding the rod must be removed before the first scraping.
Is this safe for food use/around food?
Yes. Ferrocerium does not release toxic substances when it sparks — it is only used to light the fire, without any chemicals.
