Thermoluminescence: Useful for identifying age ceramic or ceramics, you can use it up to now supplies containing crystalline minerals to a certain warming event previously (such as for example if the product was made).

Fission-track dating: an approach that find age various vitamins and glasses in line with the tracks of scratches accomplished by the spontaneous fission of uranium-238, by far the most plentiful isotope of uranium.

Potassium-argon (K-Ar) and Argon-argon (Ar-Ar): gauge the ratio of argon gasoline in igneous eruptive stone to calculate the length of time enjoys elapsed since the stone cooled and solidified.
