They are named after John Percival Droop, an English archaeologist, who first recognised the type.
The feet are high; at the upper end they bear a ridge in natural base clay colour and a similar band just below, sometimes slashed.
The earliest specimens are completely black, a type that remains in production throughout later developments.
Some early examples bear rows of bud-like decorations in the handle area.
Details of the post-540 decorative style are so similar to cups from Laconia that a connection must be assumed.
