Petrographic Study

AbstractPottery or often called gerabah is one of the results of technology that developed in the neolithic period, until now some people in Central Java in general and in the northern coast of Rembang regency in particular still found pottery craftsmen, one of them is in Balong Mulyo Village, Kragan District, Regency of Rembang. To get raw materials such as clay and sand, Balong Mulyo pottery craftsmen apparently make use of natural resources in their environment. As one artifact made from clay and sand materials, petrographically pottery can be analyzed type content and mineral percentage. The results of an analysis of petrographic samples of pottery fragments from prehistoric-protohistoric sites in the northern coast of Central Java such as Binangun, Leran, Plawangan and Tanjungan sites, have in common with the pottery samples from Balong Mulyo. This is one of the benefits of applying petrographic studies in archaeological research. In addition, the results of this petrographic study can provide an explanation that prehistoric-protohistoric humans in the northern coastal area of Central Java to meet their daily needs have utilized the natural resources of their environment, one of which is in pottery technology.Keywords: Pottery, Neolithic, Petrographic analysis, Raw material, Environment. Abstrak            Tembikar atau sering disebut gerabah adalah salah satu hasil teknologi yang berkembang pada masa neolitik, hingga sekarang sebagian masyarakat di Jawa Tengah umumnya dan di daerah pantai utara Kabupaten Rembang khususnya masih ditemukan pengrajin tembikar, salah satu di antaranya adalah di Desa Balong Mulyo, Kecamatan Kragan, Kabupaten Rembang. Untuk mendapatkan bahan baku seperti tanah liat dan pasir, para pengrajin tembikar Balong Mulyo rupa-rupanya memanfaatkan sumberdaya alam di lingkungan mereka. Sebagai salah satu artefak yang dibuat dari bahan baku tanah liat dan pasir, secara petrografis tembikar dapat dianalisis kandungan jenis dan prosentasi mineralnya. Hasil analisis petrografi sampel fragmen tembikar dari situs-situs prasejarah-protosejarah di kawasan pantai utara Jawa Tengah seperti Situs Binangun, Leran, Plawangan, dan Tanjungan, secara garis besar memiliki kesamaan dengan sampel tembikar dari Balong Mulyo. Inilah salah satu manfaat penerapan kajian petrografi dalam penelitian arkeologi. Selain itu, hasil kajian petrografi ini dapat memberikan penjelasan bahwa manusia prasejarah-protosejarah di kawasan pantai utara Jawa Tengah untuk memenuhi kebutuhan hidup sehari-hari mereka telah memanfaatkan sumberdaya alam lingkungannya, salah satu di antaranya adalah dalam teknologi pembuatan tembikar.Kata Kunci:  Tembikar, Neolitik, Analisis petrografi, Bahan baku, Lingkungan

Late Palaeolithic

The aim of the article is to present the results of a multifaceted analysis of a collection of non-flint stone artefacts obtained during excavations of the complex of Late Palaeolithic camps at site 17 in Nowogród, Golub-Dobrzyń district. It included an obsidian artefact and objects made of crystalline rocks (quartzite, quartzite sandstone, quartz, coarse sandstone and diorite), which were created as a result of knapping the raw material using techniques similar or identical to those used during the processing of flint. The results of petrographic analysis confirmed that these raw materials had come from natural resources located near the site. Most of the analysed artefacts are represented by large flakes. In addition, one chip and two tools, a multiple burin and a pebble tool, were distinguished. Use-wear analysis showed signs of use on two artefacts, including the pebble tool. The obsidian artefact is currently the northernmost Late Palaeolithic find of this type. In order to determine the geological source of the raw material, the artefact was subjected to PGAA and XRF analysis. PGAA analysis confirmed that the obsidian originated from a source in northern Slovakia (Carpathian 1 type), probably from the Cejkov or Kašov deposits, Trebišov district. The article also describes a rock crystal and a probable concretion of quartz of this type originating from site 6 in Ludowice, Wąbrzeźno district

<p>The number of iron sand reserves is mostly spread in the coastal waters of Indonesia, from the coast of Sumatra, the southern of Java to Bali, the beaches of Sulawesi, beaches in East Nusa Tenggara (NTT), and the northern coast of Papua. Total reserves for ore are 173,810,612 tons and metal as much as 25,412,652.62 tons. But its utilization was not optimal because PT. Krakatau Steel, and PT. Krakatau Posco has produced steel plates only 24,000 to 36,000 tons per year. While the need for steel plates for the shipping industry each year requires 900,000 tons per year. With the need for raw material for steel plates in the form of iron sponges with Fe ≥ 60%, PT. Krakatau Steel is still imported from abroad. The proof is PT. Krakatau Steel before and during the year 2000 still imported Iron Ore Pellets from the countries of Sweden, Chille and Brazil for 3,500,000 tons per year. This condition is the cause of the national steel industry unable to compete with the foreign steel industry because imported raw materials are subject to import duties. This is an opportunity to build a steel raw material company because all this time the steel raw material industry in Indonesia has only two companies. This condition encourages the manufacture of iron sponges, with the process of making iron sponges with technology adapted to installed production capacity. This study analysed the manufacture of iron sponges using Cipatujah iron sand, as raw material for the manufacture of iron sponges, with the results obtained in the form of iron sponges with the highest levels of Fe ≥60.44%. This can be used for the purposes of raw materials for steel making PT. Krakatau Steel (PT. KS), because so far PT. KS claims that Fe &lt;60% local sponge iron products. This can encourage the independence of steel raw materials, which impacts on the independence of the defence industry. But the government must also protect and prioritize steel raw materials for national production for national steel production. With the national government steel industry, the consortium of vendors supplying raw material (iron sponge) to maintain the quality and supply of continuous sponge iron.</p><p><strong>Keywords</strong>: iron sand, iron pellet, iron sponge</p>

The l’Hort de la Boquera site is located in the northeastern part of Iberia and its stone tool assemblage includes up to 25,000 flint artefacts. This is the first approach to the analysis of the raw material through an archaeopetrological study. Results were obtained by use of mineralogi¬cal techniques: macroscopic and petrographic analysis, Scanning Electronic Microscopy (SEM), Micro-Raman and X-Ray diffraction (XRD); additionally, Laser Ablation Inductively Coupled Plasma Mass Spectrometry was applied. It has been possible to discriminate at least four flint categories, the ‘Evaporitic flint type’ (with two local subvarieties – ‘Common evaporitic’ and ‘Garnet’ varieties) that comes from local outcrops of the Ulldemolins Complex, and two flint types that had their origin further afield: the ‘Charophyta flint type’ (coming from the Torrente de Cinca Unit) and the ‘Dark flint type’ (from the La Serra Llarga Formation).These results make this study the most comprehensive analysis of raw materials that has been carried out in the area so far

Ne Iberian Peninsula

The Picamoixons site is a rockshelter located in the province of Tarragona (NE Iberian Peninsula). It was object of two rescue campaigns during 1988 and 1993, which led to the recovery of a complete archaeological assemblage, including stone tools as well as faunal and portable art remains that date the occupation to the 14th to 11th millennium BP (calibrated). This study involves a petrographic characterisation of the stone-tool assemblage in order to establish: 1) the procurement areas, 2) the raw materials management strategies and 3) the mobility radius and territorial sizes of the hunter-gatherers groups that occupied the site. The method applied comprises in a multiscale analysis that includes systematic prospection, the petrographic characterisation of geological and archaeological samples, an analysis of the chert types represented in the knapping sequence, and the definition of the mobility axes and areas frequented according to lithic procurement.A petrographic analysis of the chert in the prospected area led to the definition of nine macroscopic varieties related to five types (Vilaplana, Morera, Maset, Vilella and Tossa cherts), related to Lower and Upper Muschelkalk (Triassic), Lutetian, Bartonian (Palaeocene) and Sannonian (Oligocene) deposits.The study of the knapping sequences indicates the main exploitation of Bartonian cherts (Tossa type), and the use of Lutetian cherts (Maset and Morera types) for configuring retouched tools. The exploitation of the remaining raw material types identified is considered sporadic and opportunistic.Defining the procurement areas enabled the mobility radius to be assessed as between 3 and 30 km, highlighting the importance of the fluvial basins as natural movement pathways. The results indicate that the main procurement territory was 16 km2 in area, associable with a forager radius. The most remote procurement distances suggest a maximum exploitation area of 260 km2, defining an intra-regional range. This range presents parallelisms with various contemporaneous hunter-gatherers groups in Western Europe, suggesting a progressive mobility reduction dynamic during the Late Pleistocene-Initial Holocene.

Insight Into

Archaeological ceramics refers to products made primarily of clay and containing variable amounts of lithic and other materials as well. The term ceramic is derived from the Greek keramos, which has been translated as "earthenware" or "burned stuff." Ceramics include products that have been fired, primarily pottery but also brick, tile, glass, plaster, and cement as well. Since pottery is by far the most important archaeologically, and the methods of sampling and study are largely applicable to the others, this chapter is devoted primarily to pottery. Pottery then is the general term used here for artifacts made entirely or largely of clay and hardened by heat. Today, a distinction is sometimes made between pottery, applied to lower-quality ceramic wares, and the higher-grade product porcelain. No such distinction will be made here, so the term pottery alone will be used. Raw material that goes into the making of a pot includes primarily clay, but also varying amounts of temper, which is added to make the material more manageable and to help preserve the worked shape of the pot during firing. Of primary interest in ceramic studies are 1. the nature and the source of the raw materials—clays, temper, and slip (applied surface pigment)—and a reconstruction of the working methods of ancient potters; 2. the physical properties of the raw materials, from their preparation as a clay-temper body through their transformations during manufacture into a final ceramic product; 3. the nature of the chemical and mineral reactions that take place during firing as a clue to the technology available to the potter; and 4. the uses, provenance, and trade of the wares produced. Much of the information needed to answer these questions is available through standard geochemical and petrographic analysis of ceramic artifacts. Insight into the working methods of ancient potters also has been obtained through ethnographic studies of cultures where, because of isolation or conservative traditions or both, ancient methods have been preserved.

This study focuses on the examination of aspects of the carinated pottery of the Dvaravati period. This type of pottery is one of the most prominent types found in a large number of Dvaravati sites in Thailand. Samples used for this study were collected from excavations at archaeological sites located in several regions of Thailand including Northern, Northeastern and Central Thailand. The carinated potteries were analyzed using petrographic analysis. The objective of this work was to examine the pottery fabric. This method is used to establish sources of raw materials, and whether production techniques, decorations, and firing temperature show patterns associated with the raw material source distributions. It is also possible to reconstruct the production technology of the vessels. Knowing the source of raw materials (source of clay and temper) and understanding the patterns of manufacturing and decorative processes help better understand material distribution patterns of the Dvaravati period. Analysis shows that Dvaravati earthenware pottery raw materials include both primary and secondary clays, and that temper used was both organic matter (rice chaff) and grogs (fired clay mixed with iron oxide). Evidence for wheel-thrown production was associated with all decoration styles, and finishing techniques included plain, polishing, incising, cord marking, red slip and black burnishing. The firing temperatures were as low as 400-550° C. These samples indicate there was general homogeneity over a wide area, but also the presence of regional groups of pottery. This suggests the widespread circulation of pottery styles among various production centers during the Dvaravati period.

&lt;p&gt;Nowadays, the production of constructional materials requires raw materials obtained through extractive activities that often imply different environmental impacts. In a perspective of a growing sensitivity towards a responsible use of natural resources the attention to materials coming from waste is focused. The waste from the municipal thermovalorization plants can be suitable for this applications, and after moderate and sustainable treatments, can find a role of raw material-second in the construction of works, reducing the need to find additional natural resources and related problems for disposal or storage. The present study aims to explore the possibility of promoting inertization (i.e. reducing the BA&amp;#8217;s release in water of environmentally dangerous chemical species below the legal thresholds) of as large a fraction of BA as possible, using ashes from one of the municipal waste incineration plants of Northern Italy, and exploiting byproducts of the incineration cycle, i.e. the spared steam from turbines, which produce electricity, and carbon dioxide from combustion fumes. The treatments discussed are as a function of the particle size (s). &amp;#160;BA are partitioned into three main classes, determined by previous studies s &amp;#8805; 4.75, 4.75 &gt; s &amp;#8805; 1, s &lt; 1 mm; %. The BA fraction with 4.75 &gt; s &amp;#8805; 1 mm was further divided into two portions to optimize the steam washing process: 4.75 &gt; s &amp;#8805; 2 mm and&amp;#160; 2 &gt; s &amp;#8805; 1 mm. BA with s &gt; 4.75 mm are treated with steam washing only. In fact, although they do not contain high concentrations of heavy metals, they largely surpass the Italian legislation thresholds related to the occurrence of chlorides and sulfates. Steam is generally available from modern incineration plants in a considerable amount, and it is more effective than water in removing a variety of impurities/low-crystallinity fragments from the surface of coarse grains. Inertization of BA with 4.75 &gt; s &amp;#8805; 1 is investigated by means of both steam washing and accelerated carbonation, to optimize the combination of these methods and expand as much as possible the s-range that requires steam washing only.&amp;#160; As to the BA fraction with s &lt; 1 mm, whose heavy metals content is likely larger than elsewhere, steam washing is of difficult application and therefore we resort to accelerated carbonation.&lt;/p&gt;

Calcium carbide Slag is from CaC2 hydrolysis reaction and will do harm to land and make pollution. Calcium carbide slag can be a substitute for limestone to produce clinker with a high portion of CaO as an excellent calcium raw material. As a kind of industrial wastes, the properties of calcium carbide slag differentiate from that of natural limestone. In the present investigation, the modern analysis methods of XRF, XRD, DTA/TG, petrographic analysis were used to compare carbide slag and limestone, and the results showed that the main chemical compositions of the calcium carbide slag were basically the same with that of natural limestone. Comparing with limestone materials, calcium carbide slag had a higher content of CaO, and the main mineral phase constituent of limestone was CaCO3, whereas the main mineral of calcium carbide slag was Ca (OH)2 with a lower decomposition temperature. It has been found that under the same temperature the amount of C3S in the clinker of calcium carbide slag batching was slightly less than that of limestone batching.

The research is devoted to the studies of raw materials and molding masses of ceramic products from the settlement Toksanbay. The purpose of the research was to study the technological aspects taking place in the course of ceramic vessels production, as well as in-depth study of the raw materials and molding masses of pottery ceramics of the settlement. During the research of samples, in addition to petrographic analysis, fragments of ceramics were studied using the binocular microscopy method, chemical experiments were carried out (using a micromethod) with the use of ammonium molybdenum, hydrochloric acid, and microenacts were checked for iron in the composition of the crock. The received result revealed that as the raw material ferruginous clay was used, and the chemical reaction to Fe of all fragments turned out to be positive. The original clay contains sand, besides this, sand feldspars, fragments of sandstones, silicified schists and epidote are noted in the sand composition. Three recipes of molding masses were revealed. The organics is stated in the form of silicified voids. The composition of organic matter showed carbonate-siliceous or carbonate-phosphate. The microreaction analysis using ammonium molybdenum (МоН4)2АmО4 determined the presence of a phosphate type in organic samples. From the organic fillers, a part of the studied samples revealed hollows of round and oval shape from the burnt organics. The study of the pottery of the settlement will be continued but it can be argued that the Toksanbay potters used local clay, and the most common impurity was organogenic limestone.
