Percussion Firestarting

I'd like to share with you something I've been doing and want your input if you have experience with it. I spent the day making fires with an iron file striker and various rocks and minerals. I wanted to see what would actually ignite char-cloth (and then get to flames). I was able to make flames using the following in conjunction with char-cloth and an iron file striker:
  • Basalt
  • Tourmaline
  • Granite
  • Gneiss
  • Quartz--Milky
  • Quartz--Clear Crystal
  • Quartz--Iron-Stained
  • Quartzite
  • Quartzite--with Rhodonite Layers
  • Chalcedony
  • Chert
  • Georgetown Flint
  • Knife River Flint
  • Ft. Payne Flint
  • Francisco Flint
  • Sandstone
  • Tecovas Jasper
  • Metasediment
  • Rhodonite-Spessartine Garnet-Quartz Mix

Although the next four minerals generate sparks, I couldn't get them to work:

  • Actinolite
  • Spessartine Garnet
  • Obsidian--I suspect it will work eventually
  • Opal--I suspect it will work eventually

I was very impressed with the "one-hit wonders," the rocks and minerals that required only one strike in order to ignite the char-cloth:

  • Granite
  • Chalcedony
  • Chert
  • Georgetown Flint
  • Knife River Flint

I hope to find the following to use in place of the iron file. I'm not sure if all of these would work, but I hope to find out someday:

  • Chromium
  • Nickel(ine)
  • Iron Pyrite
  • Marcasite
  • Iron Meteorite
  • Banded Ironstone
  • Pyrrotite
  • Pentlandite
I also want to show you the method of arranging the char-cloth that works best for me thus far.
