RK has been on public record for more than two decades for our refusal to accept the validity of C14 dating technique for antique/historic oriental carpets.
During this time-period there has been a slow but continuing trail of evidence proving our position is correct and far from the nonsensical, luddite, doubting thomas accusations others have levied.
We stake our position on what we call the contamination issue and the lack of any accepted industry standard decontamination protocol.
Today a reader informed us of a recently published scientific article that explains fossil-fuel emissions skew C14 results for articles less than 2,000 years old and render testing results unreliable.
The article written by Heather D. Graven, Department of Physics and Grantham Institute, Imperial College London England, is entitled “Impact of fossil fuel emissions on atmospheric radiocarbon and various applications of radiocarbon over this century”.
It basically states “This finding has strong and as yet unrecognized implications for many applications of radiocarbon in various fields, and it implies that radiocarbon dating may no longer provide definitive ages for samples up to 2,000 y old.”
On account of their exposure to atmospheric contamination of all types, including but not limited to fossil-fuel emissions, carpets and textiles over their life span soak up many types of contaminants and until a universal and 100 percent effective protocol is developed to remove them C14 dating will never provide even the minimum of reliability necessary to date any weaving.
