14 c dating fiasco shroud turin
When this type of measurement is made on a carbon-based sample of known age, the measured age is close to the actual age. Thus, by measuring the amount of vanillin remaining on the cloth, one might be able to estimate the age of the cloth.Rogers developed a new method of dating linen based on its vanillin (a.k.a. Rogers believes that vanillin is detectable in the sample taken for radiocarbon testing.Unfortunately, he allegedly chose to use a qualitative analysis method: He stained a sample of the shroud in his home laboratory using phloroglucinol–hydrochloric-acid reagent.If a significant amount of vanillin is present, the reagent changes its color.In the past, various methods of estimating the age of the shroud were considered: The color of the linen is one potential indicator.
, and a long-time believer that the shroud is an actual burial cloth of a crucified man which dates from the first century CE.
This would seem to make his measurements of no value.
Very small samples from the Shroud of Turin have been dated by accelerator mass spectrometry in laboratories at Arizona, Oxford and Zurich.
Jesus Christ) who was executed about 30 CE ~ mn~ 3 years by the Roman Army.
It has been shown to generate extremely precise quantitative measurements of carbohydrates, such as vanillin.
