    I saw that episode. That was part of the reason I tried it. It worked really well for them. My rocks cracked and my water didn't quite boil.

    Read the link, I just skimmed over it but I believe you have to use certain types of rock...


    i.e. limestone won't really work, while something hard like granite would be great....

    Well, you don't "HAVE" to use certain types of rock - but some are better suited than others.

    Rocks which crack can potentially be dangerous to the handler, but will still get the water to boil.

    From the article, granite is one of the worst - has fine cracks/pores which cause cracking from steam expansion. The best of the ones tested was basalt.

    you need to slowly heat the rocks to bake the moisture out of their center to keep them from exploding while being heated. theres no real cure for them exploding when theyre quenched in the water as thats rock selection. finding a flat rock to put in the center of your coals to stack your hot rocks on will keep them out of the soot/ash. an initial rinse would be advised. you can also place hot rocks in your bedding to keep warm on cold nights. exchange them when they get cold and stoke your fire

    The flat rock is a good idea, but I can't imagine having such a large fire that I could sacrifice coals, or not have active flames.
