Dating pottery archaeology
The use of ovens added new possibilities to the development of pottery.
Around the same time, some areas of South America were also developing pottery technology.
Some of these objects can be dated independently: radiocarbon dating can be applied to human and animal remains and even to charcoal.
The oldest evidence of pottery manufacture has been found at an archaeological site known as Odai Yamamoto, in Japan, where fragments from a specific vessel have been dated to about 16,500-14,920 years ago.
Another type of kiln is an updraft kiln, which is usually a cylindrical construction divided into two compartments: the lower compartment is where the fuel is placed, while the pottery is placed in the upper compartment.
This allows the heat to rise and the pottery is fired at a temperature level normally ranging from 1,000 to 1,200 degrees Celsius.
The aesthetic qualities of pottery can be analysed, and it is possible to have a better understanding of what type of pigments and other substances were known to that particular society.
In some cases the overall color of the pottery can be changed from its natural reddish to gray without the need of pigments, merely by manipulating the temperature and air influx in the kiln during the firing process.
