The defect in the carbon dating was that the samples were "uniquely coated with a yellow–brown [[plant]] gum containing dye lakes. [[Pyrolysis-mass-spectrometry]] results from the sample area coupled with microscopic and microchemical observations prove that the radiocarbon sample was not part of the original cloth of the Shroud of Turin.  The radiocarbon date was thus not valid for determining the true age of the shroud."<ref>http://greatshroudofturinfaq.com/Definitions/Thermochimica-Acta.html</ref>  Instead, "[e]stimates of the kinetics constants for the loss of vanillin from lignin indicate a much older age for the cloth than the radiocarbon analyses."<ref>http://shroudencounter.com/thermochimicaabstract.php</ref>
