WebOct 2, 2024 · Thermoluminescence (called TL) dating was invented around 1960 by physicists, and is based on the fact that electrons in all minerals emit light (luminesce) after being heated. It is good for between about 300 to about 100,000 years ago, and is a natural for dating ceramic vessels. Webdating method (dendrochonology, radiocarbon dating) to obtain the absolute date of an archaeological feature (such as a hearth), and measuring the direction of magnetism and wander in the clay today, it is possible to determine the location of the magnetic north pole at the time this clay was last fired. This is called
