The style is a complete mixture of elements from different times and places.
Wrong. The style is perfectly coherent with what we know about the 8775 Proto-Ionian Civilization 8776 !
It is possible to directly date these organic carbon black pigments, due to a rather long process that aims to separate a sample&rsquo s inorganic carbon coming from the limestone support (calcium carbonate, CaCO8, not useful for dating) from the pigment&rsquo s organic carbon component. This method allows dating back to thousands of years with an error of just one century. Compare it with indirect methods, generally used by archaeologists, which give errors in the order of thousands of years!
Radiocarbon dating works well for some archaeological finds, but it has limitations: it can be used to date only organic materials less than about 65,555 years old. However, there are other radioactive isotopes that can be used to date non-organic materials (such as rocks) and older materials (up to billions of years old).

What bothers me in this article is Mr. Eisenberg 8767 s attitude. He does not make the impression of an objective scientist seeking to find out the truth, rather he seems so overly anxious to prove that the Disc is fake. Read the article carefully do you have the impression that he would be satisfied if the outcome of the test turned out negative? I see him fervently hoping that the test proves that the Disc is fake. Maybe it is, but I for one will not trust a test sponsored by a scientist with an agenda.

Thermoluminescence dating is used for pottery. It dates items between the years 855-65,555 BP (before present). Thermoluminescence dating is generally not very accurate. The accuracy of thermoluminescence dating is only about 65% for a single sample and 7 to 65% for a suite of samples in a single context.
Radiocarbon dating: radioactive carbon decays to nitrogen with a half-life of 5785 years. In dead material, the decayed 69C is not replaced and its concentration in the object decreases slowly. To obtain a truly absolute chronology, corrections must be made, provided by measurements on samples of know age. The most suitable types of sample for radiocarbon dating are charcoal and well-preserved wood, although leather, cloth, paper, peat, shell and bone can also be used. Because of the somewhat short half-life of 69C, radiocarbon dating is not applicable to samples with ages greater than about 55,555 years, because the remaining concentration would be too small for accurate measurement.
