Old farm items?

[cluecollector]

I haven't found anything of great value but still find many farm items on my family land. Barbwire was always setting of the detector until I learned the property lines. Going inside the lines I am now finding things like this. What I can't understand is why the pottery set off the detector. Perhaps a metal based paint?

I bet if you go back to where you found the pottery you will find something under it.
