Test tube or unguentarium of natural blue colour, made of moderate quality glass with frequent very small bubbles but few impurities. It shows slight weathering, internally and externally. It was found with some parts complete such as the rim, neck, body and base, except for a small section of rim which has been possibly re-ground in antiquity. This phial has a plain everted rim which has been fire-rounded. There a slight constriction at base of neck, a slightly flattened base and slightly rough from ground-out pontil scar.
50 AD - 155 AD
