The design is etched into the surface. White or red clay is then rubbed into the engraved lines to make them stand out. Other pottery was made with animal heads, tails, feet and other features molded onto it. This kind of molded pottery is called effigy pottery. Farmers need containers that animals like rats cannot chew into to store their seeds and crops.
Pottery is also good for cooking and eating out of.
Making pottery was a woman's job. They made their pottery by coiling long strings of clay and squeezing them together. Then they would smooth the rough coils out. This is an engraved pot. The design below is the picture on the pot rolled out to see the whole thing.
