The bottom line is to always think about what exactly it is you're sampling and how it got there, and if there's any doubt, don't use it (unless there's nothing else), or if you do, make it quite clear in the report what any problems/doubts are that might be attached to the resulting date.
Oh, a good time to use wood charcoal is where you get a posthole with a nice burnt post in the bottom (sometimes you just get a charcoal ring) - always try and get seperate sub-samples from the outside rings big enough for C14 and keep them seperate, I could scream the number of times I've seen people just shovel the whole lot into a sample tub.... :face-crying:
Sorry for duplicating a lot of BAJR's post, for some reason it didn't come up when I first opened this thread page so have only just seen it, glitch in the system somewhere....
