Sometimes a black ware is 'overfired' to an ashy grey.

In such wares ornament is rare, and consists mainly of (a) incised
dots, dashes, or lines, in simple rectilinear patterns (chevrons,
zigzags, lozenges), often enhanced by a white chalky filling (V, Figs 5-
8); (b) ridges or bosses modelled in the clay surface, or adhering to
it. The forms are plump and globular, often round-bottomed or
standing on short feet. Rims are absent or ill-developed; necks
actually prolonged into trough-spouts or long beaks; handles are very
simple and short. Vases are sometimes modelled like animals, or have
human faces or breasts (V, Figs. 1-4).

These wares begin in the Stone Age, and seem to predominate in the
early and middle Bronze Age. Locally they may have lasted even later,
but the use of the potter's wheel spread rapidly in the early Bronze
Age.

B.
Hand-made wares of light-coloured clay, with painted decoration,
usually in black or reddish-brown. The paint is generally without
glaze, but sometimes is decayed and easily washes off.

The forms and ornaments resemble those of class A, but are less rude
and more varied. Distinct rims and standing-bases appear, and spouts
give place to a pinched lip.

C.
Hand-made wares of black or other dark clay, with painted decoration
in white or ochre. These fabrics are rather rare, and the paint is
easily washed off. The forms follow those of class B.
