African Sigillata 1 Base 1

Base with small-diameter ring foot from small to medium open form.

Base with ring foot usually less than 10 cm in diameter, though occasionally in the 10-13 cm range); gloss slip on both exterior and interior. 

Presumably mostly or exclusively from bowl and dish forms.  Forms likely include some of African Sigillata 1 Forms 1-10 and perhaps other forms not documented.
