Hi Ariel,
To be more precise, I was thinking of an archeological situation, where charcoal from an old fire, the rags wrapping a statue, or some other source of organics were found with the statue. Or there were remnants of a wood hilt on an old knife.
If it's a statue that was found in an antique shop, forget about it. I suppose you can get some estimate by observing rates of corrosion in an environment similar to whatever it was in for the last two millenia, but absent that, it's wild-eyed (ahem) guess time.
