An artifact or artefact (from Latin phrase arte factum, from ars skill + facere to make) is "something made or given shape by man, such as a tool or a work of art, esp an object of archaeological interest". "Artifact" is the usual spelling in the US and Canada, "Artefact" in British, Irish and Australian English (see spelling differences).
In archaeology, where the term is most commonly used, an artifact is an object recovered by some archaeological endeavor, which may have a cultural interest.
Examples include stone tools such as pottery vessels, metal objects such as guns, and items of personal adornment such as buttons, jewellery and clothing. Other examples include bone that show signs of human modification, fire cracked rocks from a hearth or plant material used for food.
Terracotta, Terra cotta or Terra-cotta (Italian: "baked earth", from the Latin terra cotta), a type of earthenware, is a clay-based unglazed or glazed ceramic, where the fired body is porous. Its uses include vessels (notably flower pots), water and waste water pipes, bricks, and surface embellishment in building construction, along with sculpture such as the Terracotta Army and Greek terracotta figurines. The term is also used to refer to items made out of this material and to its natural, brownish orange color, which varies considerably. In archaeology and art history, "terracotta" is often used of objects not made on a potter's wheel, such as figurines, where objects made on the wheel from the same material, possibly even by the same person, are called pottery; the choice of term depending on the type of object rather than the material.
