It is thought that these balls were produced as votive offerings to Hathor from as early as the 11th Dynasty though the majority date to the New Kingdom. The exact method of creation for these balls is unknown. A likely procedure however is the 'à noyau perdu' technique, in which a vegetal matter, such as reed, is compressed into the desired shape (evidence of which can be found in broken beads which show impressions of the reed fibres). A faience paste is then spread over the matter, and the whole object is heated. As the temperatures rise and the faience bakes, the vegetal matter turns to ash, creating a hollowed form.
