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.
2 pieces of quartz when struck together make fire
You can make sparks by striking pieces of quartz together but a piece of flint struck against metal such as steel is more effective.
Igneous
We need rocks to build stuff and to protect stuff.
Rubbing of every two rocks doesn't create fire... those are special type of rocks...perhaps having some amount of phosphorus in them... when they are rubbed...friction causes heating which causes them to initiate sparks
if you scrape the rockes together it will make friction which also means heat. If you do this long enough, hard enough, then you will make a fire but it isn't easy!
Minerals are not made of rocks. Rocks are aggregates of minerals.
you need a certain type of rock called flint and you need a stick and you rub the flint and the stick together to cause friction and that causes fire.
fire.
if im on the right mission, click on the guide book and put it over the fire and it will tear. but first you need to get the logs and rocks. i forgot where the logs were, but the rocks are inside the cave.
Make a signal fire.
Creating sparks with flint rocks
Flint, i think
Back in the stone age. The cavemen wanted to make fire so they used rocks.
the aboriginal people used wood and rubbed stones to make the fire and put the food over it
it starts by you having two rocks and a stick and you make a fire and leave it there and it causes a fire~
banging 2 rocks together one of them was flint.
