Talk:Obsidian hydration dating

Hi. I made some improvements. I added the new method for measurement the hydration rim with secondary ion mass spectrometry. I improved the history chapter. I added few references. I also wrote the paragraph for the reliability of the method based on Friedman’s equation. Finally I removed the cost per age calculation because it is not representative. Measurement with high-power microscopes it may cost $20 but when using SIMS the cost is range from $150 to $300. Many thanks. --Nikplas (talk) 18:12, 21 February 2010 (UTC)
