Karaz pottery is quite distinctive. Vessels of all sizes
were invariably hand-made and
generally fired twice to produce
a contrasting color scheme of red and black: a reducing (smoky) atmosphere in a kiln turned the pots black, whereas an oxidizing one basked them red.
The exterior surface of vessels were often well burnished, especially in the later periods when a
silvery sheen was produced with
graphite. Many pots were ornamented
with incised and relief patterns.
