As we’ve discussed before, the artifacts we produce are a large part of what separates us from animals, and so we are justifiably proud of them.

Since only 1 mg of carbon is required for accelerator mass spectrometry (AMS), very small iron samples can now be analyzed (50 mg of a 2.0% C iron or 1 g of a 0.1% C iron).

We anticipate that this methodology will be particularly useful to archeologists who currently have to rely on context to date iron artifacts.
