Carbon dating of the turin shroud
The gas slowly and gently oxidizes the surface of the object without damaging it to produce carbon dioxide for carbon-14 analysis.
Scientists remove a small sample from an object, treat the sample with a strong acid and a strong base, and finally burn it in a small glass chamber to produce carbon dioxide gas.
Rowe's new method eliminates the destructive steps of sampling, acid-base washes and burning.
The object is simply placed in a special chamber with a plasma, an electrically charged gas similar to those used in big-screen plasma television displays.
The Shroud of Turin, the controversial piece of linen that some believe to be the burial cloth of Jesus Christ, could finally be dated accurately.
A new method "stands to revolutionize radiocarbon dating," according to a new research.

About 1200, Constantinople was so crammed with relics that one may speak of a veritable industry with its own factories.
