Radiocarbon dating only works on carbon. It's mostly used these days to date charcoal found in archaeological contexts, assuming that the sample was excavated and maintained in completely sterile conditions. And it does require a fair amount of carbon to do the test, though a lot less since the days that Penn was actively doing RC testing.
Ceramics are usually dated by 1) style or 2) Thermoluminescense dating. There is a lab in the UK that does this. I don't recall the size of the sample they require, but it does fall under the heading "Destructive Testing."

Is there any place that does some type of carbon dating or other technique to tell how old a ceramic piece is? It seems there is Rehydroxylation dating, but not sure if there is a way to send scrapings somewhere...
