Pretreatment — Please contact us to discuss the nature of your research objective to ensure the most appropriate material selection and pretreatment of carbon dating ceramics pottery sherds. You are welcome to request that we contact you after the pretreatment to discuss options for AMS dating. The lab is more than happy to extract the residue then return the sherd to clients as requested. Please make sure to indicate on the data sheet if the sherd needs to be returned. Otherwise, it will be discarded upon completion of the analysis. The lab prefers to date the burned food residue extracted from the interior surfaces of a sherd as this offers the best chance of a date that will be representative of the last time of usage. In general the burned food residue has to be a patina that can be removed in small bits or chunks rather than a sooty powder. When the residue is so thin that only a sooty powder can be removed, it is difficult if not impossible to perform an alkali treatment to remove humic acids that may have come in contact with the material from overlying sediments or surface or ground water interactions.
Radiocarbon dating: radioactive carbon decays to nitrogen with a half-life of years. In dead material, the decayed 14C is not replaced and its concentration in the object decreases slowly. To obtain a truly absolute chronology, corrections must be made, provided by measurements on samples of know age. The most suitable types of sample for radiocarbon dating are charcoal and well-preserved wood, carbon dating ceramics leather, cloth, paper, peat, shell and bone can also be used.

Carbon dating of pottery and ceramic. Whether is it possible? Pottery and especially pottery sherds most often present at archaeological sites worldwide. They are preserved for long because of physical parameters of their matrix. In some cases they are used for dating sites 'relatively' taking into account their different peculiarities: form, picture and carbon dating ceramics, kind of matrix, kind of inclusion and additives etc.
I refunded you to save me and my support staff a huge headache. That is how I roll. You state that there are false posts in our support forums. That makes no sense whatsoever. Our support forums are threads created by our customers and responded by our support team. A simple look at our demos as well as our customer sites will show you the opposite. Not sure why you feel you have to pile more and more crap lies on top of it.
