Two non-joining fragments of apparently the same plaque. Original edges have not been preserved, but on the right side of fragment (b), a shallowly incised line is discernible, most probably marking the epigraphic field; the width of the right margin is more than 2 cm. Inscription shallowly incised probably after firing.
Porous Nile clay with considerable organic and mineral admixture (mica, quartzite, limestone?).
