Demystified: Ferrocerium and Mischmetal Fire Starter Rods

Ferrocerium and Mischmetal Fire Starter Rods

I would like to attempt to clarify the confusion often surrounding the terms “ferrocerium” and “mischmetal” when it comes to various fire starters.

My wife, who speaks fluent German, voiced confusion to the term mischmetal as it relates to ferrocerium. She explained that the term mischmetal is from the German word Mishmetall, meaning mixed metal, and that since a ferrocerium rod is made of a mixture of metal, by definition it is a mischmetal rod.

So I did a little digging and she is right. But the terms have taken on their own vernacular by the survival/fire-starting community. The terms are used to distinguish the difference between two types of fire-starting rods or tools.

What are Mischmetal and Ferrocerium?

A mischmetal, also known as cerium mischmetal, is an alloy of rare earth elements, namely those from the lanthanum series. The resultant mischmetal by itself is too soft to use as a flint, such as used in a lighter.

Therefore, it is blended with iron oxide and magnesium oxide. The resulting man-made material is called ferrocerium — probably because of the addition of the iron (ferro) and the mischmetal (cerium), hence ferrocerium—and will produce sparks to ignite tinder when scraped by a sharp edge, usually a piece of steel.

The scraper is called a striker. For years, this was the only type of spark-producing fire-starting device that came in a rod form, and was termed a ferrocerium rod or a mischmetal fire starter.

The New Mischmetal Rod

Enter the twenty-first century and a desire for a hotter fire starter rod. A new fire starter rod is introduced and it is called a mischmetal rod. I know, I know, but what can I say.

This rod allows the user to obtain both a sufficient ignition spark and an ample shower of hot burning flakes of magnesium used to ignite tinder.

Without getting too technical, this is done by lowering the iron content and increasing the magnesium content. The increased amount of magnesium, relative to the decreased iron content, results in a softer rod.

The pieces that are scraped off are larger and, after being ignited by the sparks, continue to burn after leaving the rod.

Which One is Right for You?

Ferro rods

Living Ready recommends the Swedish Firesteel 2.0 as a proven fire starter tool. Only the Living Ready Store has them for just $12.99, a great price.

There you have it. For the purpose of this book, a ferrocerium rod (also known as a ferro rod) is harder and gives lots of sparks, but the sparks don’t continue to burn.

A mischmetal rod gives large burning chunks of magnesium that continue to burn after leaving the rod.

I, being old school, still prefer the ferrocerium rod. It is hard and, in my opinion, lasts much longer than a mischmetal rod. A ferro rod only gives you sparks, but hot sparks, and they have always been adequate for me to ignite tinder. The sparks are fairly easy to aim into a tinder pile.

I have found that the large burning pieces of magnesium scraped off the mischmetal rod are more difficult to aim and the rods wear down in a much shorter time than a ferro rod.

However, when the hot burning pieces of magnesium do find their way into the tinder, they burn longer, and will even ignite a piece of paper (a ferro rod won’t do that).

To make an intelligent decision, experiment with both and determine which is best for you.

    I prefer a ferrocerium rod combined with a block of magnesium from which material can be scraped & then ignited using the ferrocerium rod. My personal favorite comes from Survivor Firestarters. The military issue models from Doan’s are also popular; just be sure to avoid the cheap Chinese imports. Mostly they’re too hard, & some of them are made of metals other than magnesium. I once got one that I’m not sure you could ignite with a blowtorch!
