Radiocarbon dating of papyrus

04 Sep

No part of the ancient script was altered or damaged during this process. "The calibrated ages of the papyrus and leather samples are tightly clustered and place the age of the Codices within the third or fourth centuries A.

The results allowed lab experts to confidently date the papyruses to between A. D.," reported Tim Jull, director of Arizona's AMS facility, and research scientist Greg Hodgins.

After placing as many loose fragments as best as possible (we will talk more about our repairs in a future post), we had some very small ones remaining with no ink or coloring which were unplaceable.

We consulted with our curators and decided that we could use a few of these small fragments for C-14 analysis.

Our research to further understand the Book of the Dead of the Goldworker Amun, Sobekmose continues. One necessary condition is that the object must fit into a certain time range.

Carbon-14 (C-14) dating was one of the first scientific analytical techniques that we employed to confirm the date for this piece, thought to be approximately 1420 B. C-14 dating requires that the material in question be at least 2,000 years old (and up to 50,000 years old) to get a result with a significant certainty.

Additionally, with works of art on paper, we do not often have an expendable sample for this type of analysis.

Since its first use in the 1940s radiocarbon dating has been the most accurate method of dating ancient objects and artifacts.

Radiocarbon, present in living organisms, decays at a constant rate in dead tissue.
