The prepared clay is a smooth, almost greasy material, very plastic and tan in color. The pottery is thrown in a traditional Zapotec method, a pair of spherical, bowl-shaped plates, one balanced on the other without a pivot. The bowl or jar is dried in the sun and
burnish ed with a stone or shard. The pottery is embellished with intricate patterns, burnished smooth, then fired in a reducing atmosphere until the correct temperature is reached when normal, oxygen-containing air is admitted for a critical period of about five minutes. This produces the black coloration. Precise temperature and time definition is difficult because this process is an intuitive one, dependent on the skill of the Zapotec potters.Black clay pottery on exhibit
