Nancy >From my reading of historical geology I have the impression that radio carbon dating works very well for 10,000 years and somewhat older -- perfect for old stone age and Neolithic, but not good for recent. Burials around Stonehenge yes, lace no.
And the loupe probably is the best portable tool, unless you have a tablet that can take pictures at very high resolution, and with enough storage space for the images.

Jeri, Laurie Waters reported at IOLI that she paid the $500 or so to have a snippet of some lace radiocarbon-dated last year, with the latest, most precise technology. The lace was thought to be 16th or 17th century. The radiocarbon dating came out with a range that included the putative date, but had such a large possible error on the date that the conclusion was that radiocarbon-dating is not precise enough to be useful. And BTW, a jeweler's loupe is still very useful 'in the field' so to speak--there's lots of better tools in the lab, but at a dealer's stall, the loupe still can't be beat, or is there a convenient tool I'm overlooking?
