Primitive Stoneware Pot

 BRAZIL - Clay Pot (Panela de Barro)

When proto-Brazilians first learned that many foodstuffs were improved, or even simply made edible, by the application of heat, they basically used two ways to apply that heat. In the rain forests of the Amazon basin and the coastal mountains, on the savannahs of western and central Brazil and on the beaches of the the country's immense coastline, Amerindians cooked their food either by direct exposure to fire (grilling, basically) or by indirect exposure. Indirect exposure involved placing the food in some sort of fired clay container and heating the food in liquid inside the pot or pan. Even the most primitive tribes of Amerindians seem to have known the technique of firing clay to make ceramic products and to have learned that once fired, ceramics can be exposed to high levels of heat without damage. Metals were unknown to these tribes, and wood was unsuitable in the presence of fire, so without clay pots they would only have been able to grill food.

not sure what the worth is, they still use these today. Good Luck
