The First and Second Gostiny Dig Sites in Tobolsk

This article continues a series of papers dedicated to introducing in the scientific discourse materials ob-tained during archaeological investigations of the cultural layer of Tobolsk — the main city of Siberia during the Russian colonization. In the course of investigation of the First and Second Gostiny dig sites, laid at the walls of Gostiny Dvor, there were recorded 24 structures of residential and economic purposes, dated to the period from the 17th to the 19th centuries on the basis of planigraphic and stratigraphic analyses and finds. The residential timber structures were single-storeyed, with saddle notch type corners (“v oblo”) with tails. Beside the houses, there were root cellars. A representative collection of finds is related to the houses: animal bones; breakage of stoneware, chinaware, and glassware; fragments of terracotta, enameled, and polychrome tile, as well as objects made of bone, leather, bark, and wood, mainly dated to the 17th — beginning of the 19th century. The most common mate-rial, amounted to several thousand items, was represented by pottery shards — pots, ewers, jars, and pans, which were used for food cooking, food storage, as well as for other everyday purposes. The porcelain ware is associated with the tea ceremony and is mainly represented by fragments of saucers, and sometimes those of drinking cups, bowls, and teapots. By the provenance, two groups of the porcelain have been identified — Chi-nese and Russian, with characteristic makers marks and patterns. The collection of iron items consists of knives, bridle bits, door hinges, latches, nails, hooks, and fragments of scissors. The leather footwear is represented by one-piece leather-hide shoes, high boots, and shoes with iron heeltaps. Another category of the finds is represented by bone combs, which were ordinarily used not only by women, but also by men. The numismatic collection com-prises 36 Russian coins and a counter pfennig struck in the workshop of Johann Adam Dietzel (master 1746–1768) in Nuremberg. The copper articles are represented by five baptismal cross pendants and by a find unique for the Siberian region — a gilded panhagia of a copper alloy with a sliding finial, several liturgical inscriptions, and images, including those of the Crucifixion, the Holy Trinity of the Old Testament, and the Mother of God of the Sign. In ge-neral, the archaeological materials of the digs show that this quarter of the uptown of Tobolsk was part of the resi-dential and commercial housing of the town, while its residents had a relatively high level of material wellbeing.

The First and the Second Regency excavations in Tobolsk

This publication continues a series of articles which introduce into scientific discourse the results of archaeo-logical research into the cultural layer of Tobolsk — the main city of Siberia during the Russian colonization pe-riod. The First and Second Regency excavations were laid on the spit of the Troitsky Cape, on the territory of the Tobolsk Kremlin, in the utility building construction zone of the Tobolsk-Tyumen diocese. Based on the historical and archival data, the identified stratigraphic columns should demonstrate the peculiarities of the formation of cultural strata in different periods of development of the city since its foundation, but unfortunately, as shown by the excavations, the early layers were severely damaged across a large area as a result of constant active recon-structions of the Kremlin. The earliest of the studied objects are the remains of a defensive line that ran along the edge of the cape in the 17th c., protecting the city from attacks. As a result, the structure of the wooden fortifica-tions of the city have been identified, which represented a high log fence, with an adjacent platform — fighting gallery — on the inner side. The presence of such structure suggests that the defensive wall carried loopholes for cannons and culverins, significantly expanding the firing potential. The nature, location and construction of this defensive line is similar to the one we found in the Chukman excavation site, on the nearby cape of Chukman. The ancient objects of the First and the Second Regency excavations include eight structures that have not been fully explored. One of them contained a rare archaeological find — the remains of a tiled stove, faced with terra-cotta, glazed, polychrome relief and painted tiles. Another building preserved in a form of a brick foundation, during the clearing of which, for the first time in Tobolsk, fragments of porcelain ware from Gardner factory were found, which was considered to be the best in Russia in the 19th century. In general, the obtained materials open new opportunities for studying the early stages of the history and culture of the first Russian capital of Siberia.

Influence of modifying coatings on dielectric permittivity of ceramic materials with composite coatings

The results of research of features of modification of aluminosilicate ceramics by suspension of fluoroplastic, aluminophosphate binder (AFS), non-aqueous compositions of polyurethane components, are presented. Samples of aluminosilicate ceramics for research were obtained by technological methods, including batch preparation operations, sample pressing, pre-annealing and sintering at a temperature of 1200–1350 °C. Polydisperse powders of aluminosilicates obtained by grinding waste of porcelain production (porcelain ware, GOST 28390-89); low-melting clay raw materials were selected as initial components. Modification of surface of aluminosilicate materials was carried out by impregnation of aqueous compositions based on a suspension of fluoroplastic and aluminophosphate binder (AFS), non-aqueous compositions of polyurethane components used in the preparation of polyurethane foam and 5 % solution of polyethylene hydrosiloxane in toluene with the formation of composite coatings on the surface of ceramic materials. It is shown that the application of organic film coatings (based on polyurethane, aluminophosphate binder and a suspension of fluoroplastic-4D, polyethylene hydrosiloxane) leads to formation of a multilayer dielectric material in which there are interface surfaces separating areas with different dielectric properties. In the presence of an external electric field, conditions are created for migration polarization between the crystalline phase of the substrate and the amorphous phase of the coating, due to the redistribution of free charges in the volume of the composite. Moreover, the chemical interaction of AFS with ceramics leads to the smoothing of the surface relief of the aluminosilicate base and the overgrowth of deep pores. Composite “aluminosilicate – AFS-fluoroplastic coating” differs from other materials, primarily in that aluminophosphate binder coating chemically reacts with the ceramic base. The impurity ions introduced during coating application, its composite structure, as well as the heterogeneity of the interface determine the pronounced frequency dependence ε and tgδ, as well as large dielectric losses of the composite in comparison with the original aluminosilicate material.

Sprawczość w fabryce porcelany

Ethnography of a porcelain factory is one of the main components of a research project called “People from the porcelain factory”. The project is carried out in the porcelain factory in Ćmielów, Poland, owned by PolskieFabrykiPorcelany “Ćmielów” i “Chodzież” S.A. The project consists of anthropological research (design anthropology and workplace anthropology) and an artistic intervention in the field. The intervention entails manufacturing Human Trace tableware set and exhibiting it both in the factory and outside, to the audience interested in design. The fieldwork in the factory allowed the author to interact with various actors of manufacturing process – both in a more observational mode of ethnography and a more participatory one during the tableware production. Witnessing the process of material transformation of raw material into a porcelain vessel was also fascinating. The article points at the role of different modes of knowing and various skills necessary for porcelain ware production and focuses on evaluation of different ways of knowing, skills and cognition.

The aim of this paper is to present the most valuable ceramic pieces from the excavations of Gyula Castle (1956-61), led by Nándor Parádi. it contains the examination of 17 pieces in all, from the groups of iznik ware, Chinese celadon, porcelain ware and the so-called „Persian” fayance from the 16th–17th centuries.

Design of an Appearance Evaluation System for Porcelain Ware

To improve the efficiency and accuracy of porcelain appearance evaluation, a kind of automatic evaluation system was presented, which composed with industrial cameras, USB(Universal Serial Bus) data acquisition card and step motor etc. The software was mainly developed with C# language. Modules such as image pre-processing and evaluation algorism etc, were developed with matlab program language. Communication between C# program and matlab program was implemented with component technology. Experiments with bowls show that the system can conveniently evaluate the porcelain by its appearance and the result is accurate.
