This coal extinguishing pot works great for putting out the fire after a BBQ. Just grab the coals with tongs, open the lid and toss them in. The extinguishing pot does the rest, no water required. Later, you can re-light the old charcoal to help your next BBQ start more quickly.
Just remember, it's made of cast iron. It will get hot! Don't store or transport it in or on inflammable surfaces.
