I found this link while cruising around with a student looking at resources for material science and archaeology. If you don't know about it, perhaps you will find is useful:
I wonder if anyone in SAS would like to contribute archaeological science information to the pages? Either way, this is a great example of an internet resource for teaching. I wish there was more of this out there.
Anyone want to take Tim's suggestion, and contribute to this source on behalf of archaeomtry?
