PRELIMINARY ANALYSIS ON SOURCING CLAY SEDIMENTS USED IN POTTERY PRODUCTION AT KUKULIK, SAINT LAWRENCE ISLAND, ALASKA JOZWIK, Diana, Department of Geology and Geophysics, Univ of Alaska Fairbanks, Fairbanks, AK 99701, [email protected] The archaeological site of Kukulik on Saint Lawrence Island was excavated by Otto Geist from 1931-1935 (Geist 1936) and includes pottery, wood, bone and ivory artifact...
Cylindrical objects made usually of fired clay but sometimes of stone were found at the Yarmukian Pottery Neolithic sites of Sha'ar HaGolan and Munhata (first half of the 8(th) millennium BP) in the Jordan Valley. Similar objects have been reported from other Near Eastern Pottery Neolithic sites. Most scholars have interpreted them as cultic objects in the shape of phalli, while others have ref...
Clay from deposit Bilalovac, Central Bosnia, was characterized by chemical, IR, XRD and DTA/TG analysis. The major mineral components are kaolinite, illite, muscovite and quartz. Raw clay may be used for pottery products and terracotta. Clay was beneficiated by wet method removing fraction over 20 μm. Beneficiation process increased content of kaolinite and decreased content of quartz. Benefici...
this study examined the adsorption behavior of two cationic dyes used in textile industries (cibasic red 46 and ci basic blue 3) on tunisian clay used in pottery. the ability of pottery clay to remove thebasic dyes from aqueous solution was compared to that of the commercial powdered activated carbon (pac)and raw clay. physicochemical characteristics of these adsorbents were performed by boehm ...
The Oneota who lived in large farming communities in the La Crosse locality from apPl"()~im(itely A.D. 1300 to 1625 are recognized by the characteristic ceramics tl1e¥ pfodllced. They manufactured shell-tempered ceramic vessels. that were much larger(indmore finely made than the grit-:-tempered pottery of the Woodland culturesthat inhabited Wisconsin prior to A.D. 1300. The use of shell· to dec...
Applicability of PGAA on pottery archaeometry has been proved in investigations of pre-Columbian figurines from Venezuela. PGAA is a non-destructive bulk analytical method, capable to determine concentration of majorand some trace components. We take part in the MÖB-DAAD project aimed to investigate Hungarian Neolithic pottery, and also in an IAEA CRP with more methodological objectives. Within...
The origin of pottery is among the most important questions inOldWorld archaeology. The author undertakes a critical review of radiocarbon dates associated with the earliest pottery-making and eliminates a number of them where the material or its context are unreliable. Using those that survive this process of ‘chronometric hygiene’, he proposes that food-containers made of burnt clay originate...
A new method for determining the vitrification rate of pottery depending on the firing temperature was devised using secondary electron images (SEI) of scanning electron microscope (SEM). Several tests were performed to establish the appropriate operating conditions of SEM and reproducibility as well as to examine the applicability of the method. The grayscale values converted from each pixel o...
Geophagia (the pica of pottery, clay, earth, or dirt) is practiced before and during pregnancy in several countries, including Mexico, Turkey, Australia, and some African countries, and has been linked with cultural fertility beliefs and the satisfaction of cravings. Unfortunately, consumption of contaminated pottery can represent a source of lead exposure. Concerns regarding ingested pottery a...
