In this paper we describe a case in which a cash book, dated of the year 2000, was sent to the Forensic Science Division, Document Laboratory, Zurich Canton Police in March 2003.
The questioned document was a list of 29 pages containing a consecutive handwritten numbering and dated entries (payments) made of blue ballpoint pen ink.
Additionally, with works of art on paper, we do not often have an expendable sample for this type of analysis.
Unlike the Fourier-Transform Infrared Spectroscopy and X-ray Fluorescence Spectroscopy described in the two previous posts which require no sample and were used to investigate pigments and adhesives used on the papyrus, C-14 dating requires a sample from the object, usually about 5 mg, which is destroyed during testing.
For several reasons, it is a rare opportunity for us to test Museum objects using this technique.
Fortunately, we believed our papyrus fit into this time range.

They have the delightful passion and enthusiasm common to TAM-goers as well as to people who are relatively new to interacting with organized skepticism.
The questioned document was suspected to have been written within a short period (e.g., a few hours) and backdated.The document lab was asked to determine the date of the entries of the questioned list.On one hand, we were asked, if the cash book had been kept on account consecutively during the period of one year, and on the other hand, the judges were interested in knowing, if the document could have been written in 2003 and back dated to 2000.Kyle Sanders I’m a combat pilot by trade but have been a hobbyist cartoonist all along. ng Meeting during our Vegas honeymoon to launch the project and get pranked by Randi at the buffet line, it was a very exciting week for us. I had been previously involved in the secular movement as an organizer, but Skepticism was the community I was looking for.I established Little Rock’s Skeptics In The Pub immediately afterwards and found my nerdy niche.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.I enjoy meeting fellow skeptics with a military background, it does not happen much.Anyway, I found them to be lovely people and I am glad to see more like them in the skeptic community.Every single one of the above mentioned articles has noted that, indeed, there is no actual evidence to suggest the text itself predates the Prophet’s lifetime.According to the logic being used by the “predating” line of thinking, If I found a scrap of paper that existed prior to my birth and wrote something on it, it means that, actually, what I had written magically predates my birth.Results show that it is possible to determine the relative age of entries written by ballpoint pen within a relatively short time scale, if storage and supporting material of the different samples are the same or at least similar.ABSTRACT: A study of four different ballpoint pen inks was carried out using methods of HPLC and solid-phase micro extraction and gas chromatography mass spectrometry.There are only a handful of labs in this country that do this kind of analysis.
