How can you tell how old a pottery shard is?
Researchers can use the shard to tell how old it is and possibly who made it. Look closely at the material of the shard. Knowing the color of the clay used will help to determine the age of the shard, as well as the name of the people who made it. Some clays completely change color when they are hardened (fired).
When was Anasazi pottery made?
Pottery occurs as early as A.D. 200 in the Anasazi region, and most of this pottery appears to have been made of floodplain or soil clays. These alluvial clays are often usable as they come from the ground, and the high iron content of the clay resulted in a brown surface color.
What did the Anasazi use their pottery for?
Baskets and Pottery They were strong beautiful baskets from part of the yucca plant or wet willows that bent easily. They carried food and water in their baskets. They even put hot stones and water in baskets to cook food. Hundred of years later, the Anasazi started making pottery for cooking and storing things.
How do you date ancient pottery?
The dating procedure involves measuring the mass of a sample of ceramic and then heating it to around 500 degrees Celsius in a furnace, which removes the water. The re-fired ceramic is then weighed immediately, using a highly accurate microbalance, to determine precisely the rate of water recombination.
How do you age an old pottery?
To determine the age of a ceramic object, a sample is weighed and then heated to around 500 degrees Celsius. This removes the combined water from the sample, which is then weighed again. After that, the sample is exposed to moist air and the rate of mass gain accurately measured over a few days.
What is a pottery shard?
A definition of sherd, according to Merriam Webster’s online dictionary, is “a fragment of a pottery vessel found on sites and in refuse deposits where pottery-making peoples have lived.” However, shard is a more generic term for “a piece or fragment of a brittle substance.” In short, sherd (short for potsherd) goes …
What did the Anasazi eat?
The most important crop for the Anasazi was corn. They crushed corn with a stone called mano. The corn that the Anasazi grew was multicolored and hard. Also, The Anasazi ate roots, berries, nuts, greens, cactus seeds, fruits, and wild honey.
How did the Anasazi decorate their pottery?
Decorated Anasazi pottery was often painted with a thin layer of pure white clay called a “slip” at this point in the process. After the pot has dried some it is smoothed and polished by rubbing with a smooth stone resulting in an appealing smooth but not exactly glossy finish.
What did the Anasazi invent?
The Anasazi, also known as the “basket makers,” are famous among anthropologists for their basket-weaving techniques. Weaving and sewing tools were used extensively by the the Anasazi people in most facets of their everyday lives.
Does carbon dating work on pottery?
What can be dated? For radiocarbon dating to be possible, the material must once have been part of a living organism. This means that things like stone, metal and pottery cannot usually be directly dated by this means unless there is some organic material embedded or left as a residue.
When did the Anasazi Indians start making pottery?
Experimentation with the geologic clays began in the 6th century, and by the beginning of the 7th century the technology had been fine-tuned, setting the stage for the next 600 years of Anasazi pottery production. The foundation of the Anasazi ceramic tradition was the cooking pot.
Where can you find shards of Indian pottery?
While it may seem like most pottery shards come from Indian tribes in the southwestern area of the United States, shards are actually found throughout the country. Researchers can use the shard to tell how old it is and possibly who made it. Look closely at the material of the shard.

What did archaeologists study in the Anasazi society?
However, instead of its beauty, archaeologists are now studying pottery technology: its origins, changes within the craft, and the organization of pottery production within Anasazi society.
