In this video you will see the process of making a fire reflector out of flat stones. Fire reflectors are crucial to keeping your fire long-lasting and hot. A reflector will reduce wind, which will expend the burning wood faster; preserving resources will help to ensure your survival in an emergency. Thin, flat stones may break due to heat, but this problem can be circumvented by placing the thin, flat stones just slightly farther from the fire. Thicker is always better, if indeed you can find thicker stones.
Start now to make sure you are staying prepared.
