What rocks do you need to make fire?
According to an IVillage expert, you should use volcanic rocks if available. Why? Because rocks from a stream or other water source tends to be wet and when they are lighted on fire they have been known to cause serious injury because they have been shown to explode. But not volcanic rock because it tends to be dry regardless of the conditions. Hope this helps.
