As part of improving my fire skills, I have given up on matches and lighters to start my fires, at least outdoors. I now use a Swedish Firesteel, and a tinder bundle which includes char cloth.
Char cloth takes a spark very easily and forms an ember that smolders for several minutes which gives one time to blow a tinder bundle into flame. Char cloth is commonly made from 100% cotton cloth (like t-shirts) but I've also made it from paper towels, cotton balls, dried leaves, punky wood, and some animal dung (mostly plant eaters like deer, moose, goats, etc.)
It is often made in fancy metal containers like Altoid tins with a small hole punched in the top, but I think that is a waste of a perfectly good container that is better used for other things, so I just use two metal cans of different diameters that I dig out of the trash. I punch a small hole with a nail in the narrower of the two, fill it with material and then invert it into the larger diameter one, and put it to heat. It will smoke out the hole and when the smoke stops you take it off the heat and let it cool before opening.
I can almost always catch a spark with the cloth on the first try. Dryer lint, another excellent tinder, often takes 5-10 tries, at least for me. A magnifying glass also works well.
Fire science fun. Try it. It's a great skill to know and practice, but unless your rocket stove has a good natural draft even when not burning, this might be a skill to practice outside.
