A fire stone is a rock of fire-resistant materials, made of sandstone and limestone that’s formed when a meteorite falls on the Earth’s crust.

The stone is often found on volcanic areas.

If you’ve ever spent time in the wilds of Yellowstone, you may have seen one of these stones.

But it’s not something you would want to bring with you to the office.

The rock is made of carbon, which is the main ingredient in petrol.

A firestone, if it’s ever found, is usually found on the surface of a lava flow or on the bottom of a rockfall.

To get the most out of the stone, you need to heat it to around 200 degrees Celsius, or nearly 3,000 degrees Fahrenheit.

If that’s too hot, you’ll burn through it quickly.

This is because the carbon molecules will split, forming a new one.

A typical firestone can burn through around 40 to 100 kilograms of carbon.

The carbon content of a firestone varies, depending on where the stone is found.

The lighter the stone and the greater the amount of carbon it contains, the more carbon is burned off.

A rock made from volcanic rock would have the same amount of burning carbon.

However, a fire-stone made from lava rock is probably more prone to burn than a volcanic rock.

For this reason, some people suggest bringing a fire rock to the laboratory, to burn carbon, and to be sure it’s fire-proof.

In this case, it’s likely you’ll need a lighter to light the stone.

But if you’re looking to burn a fire in your office, a lighter might not be the best idea.

When you get to your desk, the stone should be in the same spot as the flame.

The light from your desk should illuminate the stone to a degree, allowing the carbon to be burned off more quickly.

You might be surprised at the number of times you’ll want to make sure that the stone has the same flame that you use to light your desk.

It can be hard to tell the difference between a fire and a spark, because the flame is very bright.

But a spark can be easily extinguished with a lighter.

In a fire, it burns hotter than a flame, so you’ll probably need to use a lighter than the one you’re using.

If the stone isn’t light enough, the carbon will burn out.

The next step, if you have the stone available, is to burn the carbon with a fire extinguisher.

In other words, you can put the stone in the fire, set the fire in the middle of the fire and then extinguish the fire with the extinguisher (usually the lighter).

If you’re not sure how to do this, ask your supervisor.

This isn’t always the case.

It’s also possible to make the stone burn through carbon, but you need a flame that can be extinguished with the fire extinguishers.

If there’s a fire you don’t know how to put out, try searching for information online or on YouTube.

If your fire is burning through a very fine, solid material like sand, it can take quite a while to put it out.

If it burns through a rock or a rock fragment, it may take up to an hour to extinguish with a small amount of water.
