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.
