While charcoal is not pure carbon, it is almost there. It is actually a hydrocarbon. Charcoal is formed when it is slowly burned, without much oxygen, allowing for water and other elements to be stripped away. What is left, when dry, is dark ashy chunks, which we call charcoal.
Charcoal has many uses, particularly enjoyed during the summer months of grilling outside. It burns at a higher temperature and does not give off as much smoke. This makes it an ideal method of burning and cooking. This, however, is just the tip of the iceberg. Activated charcoal is used for forensic sciences, which helps in activating and finding evidence that is harder to see with the naked eye.
It can also be used as carbon for chemical reactions. Because of the low smoke, it is a viable option for many different uses. Charcoal has been used since ancient times and was common in many places that had a wide variety of wood. It is also used for art, filtration systems, and some medications.
