Thanks everyone for your responses, especially to Sapper4083 for the information.
Even before posting the idea, I was thinking that my recipie would create something that would burn but it probably wouldn't throw out the heat necessary to boil 350ml of water. Also, I figured there would be a lot of soot involved.
Anyway it was just an idea. I'll probably go ahead and try the candle wax, sawdust, and egg box version. The guy in the video seemed to get a good flame with it.
I am in the midst of drying bush trimmings and roots so that I have a readied bag of tinder kindling. I just need to make a pouch for it.
Chubbs' pepped up candlewax, woodshavings, brasso, and white spirit sounds interesting.
Ok try these guys, you've prob tried them already but take a cottonball and melt candle wax and soak the cottonball in the wax, let it soak right in the(they still fluff up and catch a spark) and whilst still wet mold into a shape you want (small to go in a tin/pouch) and trust me, these bad boys burn for about 10mins and are waterproof and VERY windproof! They burn hot as well and can boil water by them selfs in about 5ish mins. Cheap and VERY great tinder and its all from stuff you have in your house, i can't say enough for these great little fire starters!
