by Dr Carl Wieland An attempt to explain this very important method of dating and the way in which, when fully understood, it supports a ‘short’ timescale.
In other words, we have a ‘clock’ which starts ticking at the moment something dies.
Graphite, one of the softest materials known, is a form of carbon that is primarily used as a lubricant.
Although it does occur naturally, most commercial graphite is produced by treating petroleum coke, a black tar residue remaining after the refinement of crude oil, in an oxygen-free oven.
This black soot, also known as lampblack, gas black, channel black or carbon black, is used to make inks, paints and rubber products.
It can also be pressed into shapes and is used to form the cores of most dry cell batteries, among other things.
