Some knowledge about lava:
Volcanic activity have make the magma become the lava after 100 million years! The heat resistance of this kind stone is very strong, also include anti-cracking!
The air permeability of this kind stone tool is very good! The food will not easily burned and more less smoke!
When you heat the stone tool, it will release far infrared, it can keep the food more fresh!
This kind stone tool have been used for many thousand years, although in the modern time, a lot of people still use it to cook the food!

Instructions:
Put the stone tool in the brine, and boil it for about 5 minutes!
When the brine cold, clean the brine and smear some edible oil to the surface of stone tool!
When you use it, for the first 4-5 minutes, burn it by small fire and then big fire!
At the beginning do not use the big fire in order to save time, if the temperature increase a lot at a short time, it will make the stone tool cracking, it will also reduce the effect of far infrared, make the food more easily burned! So it will make the stone tool lost his effect! The available temperature is 180---200.

The stone is nature material, it will need more time to heat it than steel, and when you heat it, it will keep hot for a long time! So the energy you use on stone tool will the same as steel!
