Romano British New Forest Ware Bottle
This selection of sherds are all of the same vessel, a delicate, long necked bottle which was found on Highdown Hill in the 1960s. This shape is often referred to as uguentarium, and the size is fairly small (compared to something like an amphora) so this was probably used for oil or some other liquid stored in smaller quantities - such as perfume, balsam, honey, or even cosmetics.
The colour and composition of the ceramic also suggests it originates from one of the numerous New Forest potteries which were producing wares during the Romano-British period.
