Our magnesium is the hottest burning magnesium you can by. Start a fire quickly with a ferro rod, torch lighter or wooden matches, burns white hot ( 4000 °) even in wet conditions. The lightest and hottest fire starting material you can buy. Will light wet tinder when nothing else will. I have used magnesium while backpacking from sea level to Mt. Whitney at 14000 plus fee for over 30 years. That's why it is so popular with all outdoors enthusiast all over the US. Thanks for looking.
