A Reading on Kalpuregan Pottery Using Petrography

The lifespan of Kalpuregan’s pottery goes back to 3,000 BC and is probably one of the few areas in the country where the same traditional methods of designing and making pottery are done there now. Recognition of indigenous phenomena is possible by understanding human activities in the environment around them. Laboratory studies for analyzing pre-historic pottery in Iran will give us a better understanding of the production and distribution process. In the meantime, pottery items in Kalpuregan come from technology and firing clay. Clay is abundantly found on the surface of the earth. So far, no reports have been published on the recognition of elements that form containers or potteries in the Kalpuregan, district of Saravan. Most of researches have been done on the motifs and ways of making this pottery. The aim of this study was to identify Kalpuregan pottery using petrographic test. The results showed that Kalpuregan soil is secondary clay. These types of clays include various types such as ballclay, stoneware, red clays, marl, bentonite and refractory clay. The components of pottery comprise the following three major categories: clays, fillers, and fluxes. Clay has other elements such as titanium oxide, potassium oxide, sodium oxide, magnesium oxide, iron oxide and calcium oxide, the percentage of which is different depending on the type of soil. In the process of research, after the petrographic examination, it was found that most of the elements of the clay for pottery in Kalpuregan are Quartz minerals, which are seen as phenocryst and polycrystalline. This type of mineral makes up 20% of the sample volume. In the course of research on the type of fire in Kalpuregan pottery kilns, it was found that the color change of pottery after firing is due to the temperature conditions of pottery kilns in this area.
