What I need to know is would they have to destroy/break/use the blade in any way to carbon date it?
I have an antiques dealer who specialises in blades/weaponry especially east Asian stuff. I'm trying to get her the entire piece of the blade, without ruining it in anyway.
Would a mass spectrometer be able to carbon date it? Is carbon dating even feasible? If it isn't, what methods might they use to say "Oh! Look it's not modern it's about '#x' centuries old." This would be the crime lab doing that, before kicking it to the antiquities gal.
Any help? Alternate ideas? Help?
Thanks in advance.
Edit: Alright here's what I need:
The CSIs find a two inch piece of a katana --it needs to be at least 14th/15th century. Now, I need a way for them to kick that over to my antique blade expert. I already know what she can look at and give them possible makers/school of the maker.
What I can't figure out --and hence the carbon dating-- is how to get it, realistically, from them to her. So, ideas?
