Firesteel Decay in Storage
« on: January 30, 2013, 02:46:46 AM »
hi all!

Over a Greek survival forum we had 3 cases of firesteel degradation in survival kits.

in 2 cases there was erosion on the rod and a fine grey dust all around.

The other case was scary.





flint dissapeared completely!

All the kits were sealed and left stored. There were no indications of moisture (I am adamant in my case) but all kits had Bic lighters in them, that they were not jammed in anyway to avoid gas leakage.

What is going on?

Mischmetal is mixed with iron oxide and magnesium oxide to make Ferrocerium sparkers. It is very susceptible to corrosion through air and moisture.

If you take a Bic lighter out of its original packaging to repackage it you have the potential of picking up moisture.

You can coat firesteels (ferro rods) in Fingernail Polish or Plasti-Dip to help protect them from corrosion. Obviously, you'll need to pull off the Plasti-Dip or scrape off the Fingernail Polish before they'll spark.

I just let some of my firesteels develop the outer layer of corrosion and scrape that off before use.

I apply a light coat of silicon grease to my long term storage firesteel rods and think the problem is more pronounced in the combo magnesium/steel rod units as dissimilar metals tend to react over time (I can measure a voltage generated on some of my 2 metal magnesium block with iron rod units.)

I have several ferrocium rods which I have had nearly 20 years, and I live in a very humid climate, with no issues. However, I once had a problem with the tiny ferrocium rods for a zippo lighter. I always put the extra flints under the felt flap. I have been doing this for probably 20 years. There way one time when I went to refill my lighter that I noticed the flints looked "bubbly". A touched them and they all disintegrated. It only happened that once.

I had a plain ferro rod placed in a mint can kit, kept it full of gear and then I ran electrical tape over the lid. around 2-3 years later I opened it to get the $40 out for an emergency gas need and found the rod severely deteriorated to point of not being useful also my fishing hooks were almost completely rusted too.

You just can't have dissimilar metals touching,it promotes corrosion.

I have been getting trouble with 3 of mine...one is all corroded out, and I am getting haziness in the ziplock back from 2 others.
All the same kind, the softer one. A light-my-fire one tat is definetely froma different harder metal is just fine.

Nail polish to the rescue....
