Studying influence of element Gd3+ on the magneto-optic properties of the tellurite glass 
This paper presents the results of research on the tellurite oxide glasses containing Gd3+ elements addition. The evaluation of the magnetic properties of the investigated materials was based on the determination of the dominant type of magnetic order by measuring the DC magnetic susceptibility. Their magneto-optic properties were determined on the base of the Faraday effect measurements and Verdet constant calculated from the turn angle of the surface light polarization. The results of magnetic susceptibility measurements indicate the change in the nature of magnetic ordering induced by the addition of gadolinium ions. Parent glass Te2 is a typical paramagnetic. The addition of gadolinium ions to the parent glass caused the change in magnetic ordering from paramagnetic to diamagnetic. With the change in the nature of magnetic ordering magneto-optic effect is reduced. An increase amount of point defects and an increase of average volume defect sizes that was observed on the basis of PALS, and a small value of magnetic susceptibility in this case may influence such behavior of the magneto-optic effect. The obtained results can provide important advises on the development of new materials possess unique magneto-optic properties for applications in optoelectronic devices.

Kurt Randhahn's artistic pottery workshop in Bolesławiec – a forgotten episode from the Art Nouveau period
Kurt Randhahn, was a lecturer in the Ceramic Vocational School of Bolesławiec, and also managed an artistic pottery in this city between 1899 and 1906. What distinguished it from other works, was the elegant and exclusive assortment of products (vases, jugs, bowls, fi gurative works), decorated with drip glaze, opaque glaze, half-opaque, so-called alabaster glaze, mirrors glaze and modern paint layers. The works were created on the basis of the designs made by Berlin sculptors: Arthur Lewin-Funcke, Konstantin Stark, August Gaul and Carl Stork, as well as artists from Bolesławiec: Ernst Heinecke and Hermann Knauer. Randhahn’s ceramics was highly appraised by critics and won numerous awards, among other things: a honorary diploma on the 1st International Modern Decorative Arts Exhibition in Turin in 1902 and a silver medal on the World Exhibition in Saint Louis in the United States in 1904.

The influence of ecological characteristics of energy sources on environmental burden accompanying fl oat glass manufacture
This paper presents an analysis of a potential impact of electric energy from selected primary energy sources and natural gas from various European countries on environmental burden generated by the fl oat glass production process. In case of the group of European countries taken under consideration the range of values of the cumulated Pt index was relatively wide, from 98.5 Pt/t to 134 Pt/t of glass sheets. Lower burdens were predicted for electric energy generated from renewable primary energy sources and nuclear energy. It has been shown that it is ecologically more
advantageous to satisfy energy needs of the manufacturing process with natural gas than with electric energy.

Application of mercury porosimetry in evaluation of the infl uence of thermal shocks on changes in the texture and pore size distribution of magnesia-chrome refractory materials
The mercury porosimetry method is one of basic measuring techniques for the industry of catalysts, ceramics, active carbons and many others. There is also a wide range of possibilities of using mercury porosimetry in the research fi eld related to refractory ceramics design, production and application. The aim of the article is to present one of possible examples of solving research problems related to the determination of textural changes in magnesia-chrome materials subjected to thermal shocks. Analyses of the pore size distribution of 6 magnesiachrome materials characterised by different shock resistance were performed. The investigations were conducted on single samples subjected to 5 and 10 air thermal shocks and their results were compared to the values obtained for the original samples. It was found that in all the examined samples the median diameter of samples subjected to thermal shocks increased. At the same time changes in the pore size distribution were observed, which can be related to the materials’ resistance to thermal shocks. In the case of materials characterized by enhanced thermal shock resistance the number of 10-30 µm pores was increased, whereas in materials characterized by lower thermal shock resistance the increased number of pores was noted for the pore size of 30-90 µm. From the point of view of the quoted example, porosimetric tests should be considered very useful in the solving of research problems related to the effect of destructive factors on refractory ceramics.

Introduction to the analysis of the ceramists lumbar spine overload, based on a literature review.
When describing the hazards associated with the work with ceramics, resarchers were focused only on the poisoning by the toxic fumes, or danger caused by being in dusty areas. Based on the literature and analyzing the way in which ceramists are working, we came to the conclusion that the another work hazard in that kind of the activity is overloading of the lower back. Pain in the lumbar spine is a result of the overloading spine stabilizers, and the intervertebral disc damage, which are caused by a big compression and shear force. These factors appear because of the poor posture during work /especially when lifting heavy objects/ as well as the persistence of a static position.

Identification of the phenomenon of discoloration on Low-E coating of glass pane used in insulated glass units and its elimination
Akaganeite is one of allotropic form of iron oxyhydroxide. Due to its tunnel crystalline structure, it is considered a promising material for sorption applications e.g. for heavy metal removal from water. In this work we present a relatively simple and effective processing route to form ß-FeO(OH) nanoparticles onto surface of carbon nanotubes. Such carbon tubes can be used as a modifier of filter materials for water treatment. Introduction of an active component on the surface of either polymeric or ceramic membrane enables simultaneous retention of solid particles, adsorption of heavy metal ions and provides protection against biofouling.

Synthesis of wollastonite on the basis of common raw materials
Wollastonite is a mineral used in various industries. Since there is no economically important deposits of wollastonite in Central Europe, groups of experiments were performed to prepare wollastonite based on cheap natural raw materials. The solid statereaction method was selected with interval of temperature in the range of 1000-1300°C. Lacustrine chalk, limestone and calcite veins were sources of calcium, whereas glass sand and quartzite schist were used as a source of silica. Best results were obtained for lacustrine chalk and quartzite schist. Another important factor is pressing before synthesis – better results were obtained for non-pressed samples.

Examples of the Nanoparticles Produced by Microwave Solvothermal Synthesis (MSS) Route
Microwave solvothermal synthesis (MSS) is an example of microwave assisted wet chemical synthesis process. Microwave heating enables a precise control of the reaction time, fast heating and reducing the thermal gradients. This results in a better crystallinity of the nanoparticles comparing to the precipitation process, and a narrow size distribution. An additional advantage is a reduced synthesis temperature, since no calcination is need. In the paper we presented two new reactors used for the MSS process. We have shown their applications in the synthesis of nanohydroksyapatite ZnO and ZrO2, as well as the enhanced control of their properties possible due to the use of microwaves. The MSS-1 and MSS-2 reactors enable industrial scale production of nanoparticles.

Pride, Pottery and Nationalism in Nineteenth-Century Ireland
Throughout the nineteenth century it was oftentimes mentioned by British politicians or the British press that Ireland should utilize its natural resources in order to improve its condition. In the 1850s the discovery of feldspar and kaolin in County Fermanagh in the north-western part of Ireland ushered in the pottery industry on the Emerald Isle. The Belleek pottery allowed the Irish to feel proud. What is more, the clayware from Belleek found patrons in Queen Victoria and her son, who bought some specimens and, thus, popularized it in Great Britain. On the heels of the spectacular success of the Belleek came Fredrick Vodrey who not only produced excellent pottery but by employing Celtic motifs became a part of the Gaelic Revival, which helped to the Irish to bolster their national identity and mitigate the infl uence of Anglo-Saxon culture. The article shows what role the Belleek and Vodrian pottery played in Ireland in the nineteenth century when the Irish where trying to gain independence.

Maiolica from Nieborów and the discussion on „national art”
The maiolica manufactory in Nieborów was established by prince Michał Piotr Radziwiłł in 1881. Its director was Stanisław Thiele, who had worked in Nevers, France and in Ćmielów. Maiolica from Nieborów reflects the style popular in Europe at that time. It is eclectical, has the forms similar to French or Italian wares. Warsaw journals got involved in heated debates about the style of Nieborów maiolicas. They were criticised for their „Old German” forms and „garish decoration”, it was suggested that inspiration should be drawn from Polish folk pottery. Today, however, the maiolica from Nieborów is seen as one of the most interesting examples of European historicist pottery.

Mechanical properties of silicon nitride (Si3N4) submitted to Hot Isostatic Pressing and pressureless sintering process – comparative analysis

In the presented paper mechanical properties of silicon nitride (Si3N4) material were studied. Silicon nitride samples were obtained from commercially available powder. Two paths of ceramic manufacturing were applied to obtain fully densifi ed bodies. All of the samples were sintered in nitrogen in atmospheric pressure. Part of the samples were additionally subjected to Hot Isostatic Pressing (HIP). Apparent density, bending strength, Vickers hardness and fracture toughness were measured for the two set of samples, which differed in preparation path. The results were analyzed in order to estimate the infl uence of pressure assisted post-sintering (HIP process) on the microstructure and mechanical properties of silicon nitride material.

Paxton Vobiscum’: Joseph Paxton and the phenomenon of the Crystal Palace

The article deals with the history of the success of the Crystal Palace that was built in London as the venue of the Great Exhibition of 1851. It symbolized the might of the British Empire as well as the ingenuity of its author, a gardener, Joseph Paxton (1803-1865). The erection of such an impressive building was possible thanks to the outcomes of the Industrial Revolution and Paxton’s experiments with the use of glass and steel. Being initially a source of disputes and anxiety, the Crystal Palace became a major attraction of the Great Exhibition. In addition, it allowed Paxton to go down in history as one of the best architects of the Victorian period.

Clays from selected lignite deposits in Poland as a potential Raw material for ceramic industry

Accompanying clay raw materials from lignite mines located in Central Poland were tested as raw materials for building ceramics industry. It was concluded that mineral composition has a decisive impact on technological properties of clay rocks. Rocks containing mixture of kaolinite, smectites and quartz have the best properties for ceramic uses. Clayey rocks overlie “Adamów” lignite deposit. On the other hand, most of clayey rocks from “Szczerców” deposit showed too high shrinkage and plasticity. This property can be easily correlated with very high content of smectites. Only few samples from “Szczerców” deposit have good ceramic properties, but unfortunately contain too many larger grains of carbonates, which makes them impossible to use in building ceramics industry.

Glass-ionomer cement and implants for use in otosurgery
In this paper glass-ionomer cement and implants for use in otosurgery, which were developed and produced at the Institute of Ceramics and Building Materials, were presented. Treatment of hypoacusia requires defects to be reconstructed in the ossicular chain of middle ear in the cases of pathology resulting from chronic ear inflammations, trauma or congenital malformations. The clinical studies have been performed at the Institute of Physiology and Pathology of Hearing in Kajetany. Results of these long-term studies were presented. The application of glass-ionomer materials is the best method giving excellent results with regard to the reconstruction of a damaged conducting system in the middle ear. The use of cement and implants allows the wide range of anatomical reconstructions of bone defects that are result of disease processes or surgical removal. The anatomic reconstructions allow to restore primary and optimal function of the treated tissues. Application of glass-ionomer implants enables significant reduction in operation time. The glass-ionomer cement and implants are equally useful for reconstructive surgery in children and adults.

Glasses with energy – saving low-emissive and solar control low-emissive coatings

Coating of the glass surface with thin films of metals and metal compounds such metal oxides and the others is a very effective way to obtain the new properties of the glass without necessity to modify the bulk glass composition. The thin film coated glass is commonly used in buildings with aim to enhance the user’s comfort and energy saving. The coatings of metal compounds on glass may be obtained both “on-line” during the forming process and „off-line”, but In that case the glass sheets needs to be carefully cleaned before coating process. Thin films of metals for low emissive glasses needs to be coated „off-line” in the vacuum conditions. The method commonly used in commercial production of energy saving low-emissive (Low-E) glasses is magnetron sputtering. In this paper there some basic information on the properties and coating methods used in glass industry for producing the Low-E and Solar-Low-E glasses have been presented.
