The potters of the village of Mata Ortiz in the Casas
Grandes area of Mexico, about 100 miles south of the border with New
Mexico, have established a potting community that is very creative.
Potters seem to vie with each other for the next innovation or the
next level of excellence in quality.
The original Casas Grandes people had a tradition of
pottery making beginning about 1060 A.D. The art was lost after 1340
A.D. until a Mata Ortiz resident, Juan Quezada, figured out the old
way of making pottery from pot fragments he found and taught the
people of his village. He has spent his life training the young
people there how to mix the clay, shape the bowls and jars, decorate
them, and fire them outside in homemade kilns using wood and cow dung.
Clay is brought down from the mountains in the area.
The various colors are red, gray, orange, and pure white. The clay is
|
dried, ground by hand on a stone metate, and mixed with grit. Then
it is sifted and ground to a fine powder. After the powder is mixed
with water, it is spread out on a gypsum slab to cure for two to three
weeks. More water is added, and the clay is kneaded to a proper
consistency for pottery making.
To form the pot, a clay "tortilla" is patted out and
then pressed into a shallow bowl mold. This gives many of
the pots their characteristic, rounded bottoms, and traditionally,
would make the pot a good shape doe evenly heating foods over a fire.
A thick "donut" of clay is placed on top of this base. The pot
is shaped up into a very thin wall, usually by pinching, sometimes by
coiling and smoothing the clay. Finally, a small "donut" of clay
is added at the top so that the rim can be shaped.
After being smoothed with a piece of hacksaw blade, the
pot is dried, finished with sandpaper, and polished with a stone to a
high shine. The matte design is added by making a "slip" or
paint of water and clay. Often using only a single hair from the
head of the potter, the fine lines and incredible designs are painted
on using hand-eye coordination and the artist's artistic imagination.
The pot is fired to harden the clay. First the
pot is warmed in the sun. Outside, the pot is heated in an
efficient, hot fire which can reach a temperature of about 1220
degrees Fahrenheit. The fuel is cattle dung and cottonwood.
Manure from range-fed cattle is preferred to that from grain-fed
cattle because it burns more cleanly.
If a black pot is desired, then the firing conditions
are altered. Pulverized dung is placed beneath the pot after
which the pot is covered with a metal box. A clean, hot fire
burns on the outside of the metal box, and the pulverized dung burns
as an oxygen-poor, smoky fire inside the metal box. This process
both hardens and blackens the pot. |
