Permission near roman kiln site - Oxfordshire

[Panam39]

I've recently got a metal detector and managed to find myself my first permission near the site of a roman kiln in central Oxfordshire.

I found several bits of pottery buried deep within the field I was on and was hoping anyone here could help me with a brief identification guide for roman pottery in the Oxford region.

Thanks in advance
