What is the difference between magnesium and the front of stone? What will last longer?

I'm working on a project with my nephew. your project includes the creation of "sparks". First, you can clarify the difference for us. Then, can you let us know that one in theory should last longer. For example, if you were to strike the same weight and magnesium rod, Compare this with a weight and size stone bar, that one should last longer? Are there any other material that creates sparks?

A good way to make sparks with small pieces of burning metal. Can light metal with a flame, but when struck, some metals are produced chips that light up in the air alone. These metals are called pyrophoric. This is because metals are protected by a thin oxide layer that protects the rest of the metal from reaction with oxygen in the air - this oxide layer on the metal surface was first exposed to oxygen. When the metal is a terrain or collision, small particles are broken, and these particles have not yet protective oxide layer. The formation of this layer creates heat, as the reaction is exothermic. In a large block of metal, this heat is dissipated easily, but with small particles, heat builds up, and the particles tend to become hot enough to burn. The heat from the friction of metal grinding is also important to get particles to their ignition temperature. Several exhibit this property. More commonly, you may have seen sparks being thrown out of steel or iron when is ground. Titanium, uranium, and most of the lanthanides also do the same. This leads to the stone: stone, a rock containing silica is harder than steel, and small pieces of steel splinter when struck against it. These bits turn, and turn into sparks. However, the "stone" is commonly Firestarters-resistance and is actually an alloy of iron and a mixture of lanthanide (because these metals are chemically similar and are found together in minerals same, it is cheaper to produce a mixed alloy instead of separate, but some are very rare and expensive, once they are separated). The metal alloy called Auer or Ferro (ferro-referring to the iron and cerium lanthanides present principal). This type of stone, it also creates sparks when hitting a steel tool, but bit chip instead of steel, steel chips out of bits of this alloy, and the sparks being. Usually Magnesium Firestarters consist of a block of magnesium and a This metal strip Auer. These are used by the scraping of the magnesium shavings with a knife and then hit the stone to produce sparks and ignite the magnesium. Thus, magnesium not really produce sparks - only help you get started the fire - and you can start a fire with only the stone (sometimes sold on its own as Firestarter). So a real stone bar last almost forever (a bit will be missing with each use) - the steel is consumed to create sparks. With magnesium metal removal or "firestone" bar, this material is to be consumed so that sparks, and it will not last. Sorry for the long answer.
