Introduction
On September 2001, an anonymous
collector brought a stone tablet
with an allegedly ancient Hebrew
inscription, attributed to Joash,
King of Judah, to the Geological
Survey of Israel (GSI) in order to
check its authenticity. Three
experts from the GSI studied the
tablet and the patina coating its
surface by various chemical and
mineralogical methods. In addition,
tiny carbonized particles from the
patina were dated by radiocarbon
AMS technique in the Beta
Radiocarbon Dating Laboratory at
Miami, Florida.
