These three methods are not fool proof and only offer a reasonable guess as to the date of very old artifacts. He converted the carbon in his sample to lamp black soot and coated the inner surface of a cylinder with it.

Eventually the entire ecosystem community of plants and animals of the planet including humans is filled with a concentration of carbon 14. When the animal or plant dies it stops exchanging carbon with its environment and from that point onwards the amount of 14 14 14 c in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.
