Bronze dating

Voltammetric experiments produce current–voltage curves that have characteristic shapes for many compounds.

In order to date copper-containing, archaeological finds, a team led by Antonio Doménech-Carbó at the University of Valencia examined the ratios of two different copper oxides, tenorite and cuprite, that can be differentiated and quantified based on their voltammetric curves.

The sample selection and preparation protocols of the different kind of organic materials (charred wood, vegetal remains and animal hairs) are described as well as the interpretation of the results in the frame of the current dating hypotheses and available analytical information about the casting technology.

Subsequent irradiation, for example if an x-ray is taken, can affect accuracy, as will the "annual dose" of radiation a buried object has received from the surrounding soil.

Ideally this is assessed by measurements made at the precise findspot over a long period.

The heating must have taken the object above 500° C, which covers most ceramics, although very high-fired porcelain creates other difficulties.

It will often work well with stones that have been heated by fire.
