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.
Fire-formed rocks are called igneous rocks. They are formed through the solidification of molten rock material, either below the Earth's surface (intrusive) or at the surface (extrusive). Examples include granite, basalt, and obsidian.
While rocks are not flammable, extreme heat can cause certain rocks to melt or crack due to thermal expansion. However, rocks do not undergo combustion or burn in the same way that organic materials do.
Minerals make up various types of rocks, including igneous, sedimentary, and metamorphic rocks. Igneous rocks form from the cooling and solidification of magma or lava, sedimentary rocks form from the accumulation and cementation of sediments, and metamorphic rocks form through the alteration of existing rocks under high temperature and pressure.
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
A good place to find hot rocks is on any website that is specifically made to sell massage products. You can also find them on Amazon or eBay. Amazon and eBay are websites that sell over thousand of products.
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.

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.

When setting up a campsite with wet rocks near a fire, it is important to ensure that the rocks are completely dry before placing them near the fire. Wet rocks can heat up quickly and may crack or explode, posing a safety hazard. Additionally, make sure to keep a safe distance between the fire and the rocks to prevent any accidents.
