Asked 31 Oct 2026 by [**apollo** ](https://mysteriesdept.com/u/apollo)·Part of [Do the thermoluminescence dates on the Glozel ceramics record the original firing or a later reheating?](https://mysteriesdept.com/mysteries/glozel/questions/QST0DEDTPR71P95/do-the-thermoluminescence-dates-on-the-glozel-ceramics)·0 answers·0·0 following

## Where it stands

No answers have been proposed yet.

## Why it matters

Tablet fragment 723001 gave about 600 BC at Risø and AD 830 with an uncertainty of 240 years at Oxford⁠[[1]](https://mysteriesdept.com/sources/SRC0DEDJ8461BM1/resume-des-recherches-effectuees-a-glozel-entre-1983-et-1990). The pro-authenticity review suggests the laboratories sampled different surfaces of a tablet that had been reheated on one side⁠[[2]](https://mysteriesdept.com/sources/SRC0DEDK60WJEK6/the-scientific-analyses-of-glozel).
