Painted ceramics of Hallstatt Period from Poland     
In the article the author describes the phenomenon of painting the ceramic wares that emerged in south-western Poland during Hallstatt Period (about 700-450 BC). The ceramic forms, the process of painting, decorative motifs and their meaning were presented. Considerable attention was also paid to the genesis and the process of formation the manner of painting the pottery, its penetration to the territory of Poland and its cultural and social consequences.

The possibility of usage mine waste TG3 clay from Turoszów in sanitary ware production
In this paper preliminary results of imputing TG3 clay, such as cheap and alternative material in sanitary ware have been presented. The main purpose was to find the highest amount of TG3 clay that is possible to replace the original raw clay material for producing ceramics parts without decreasing technological parameters, such as: viscosity, density, fi ltration etc. The maximum was reached on level 37% in all components ratio. The over dosage changes clay equilibrium in suspension and among others has infl uence on burning temperature and deformations.

Pottery grey and black Polish-Lithuanian borderland
The article presents a short story of potteries’ development in the borderland of Poland and Lithuania. Moreover, the secrets of production of siwak in Poland, bearing in mind one of the greatest centres, Czarna Wieś Kościelna, as well as black ceramics in Lithuania. The above mentioned black ceramics are being made in the Dzukija National Park, nearby Merkine, by the Niemen river. Particular stress was put on the methods of work, tools, ways of decoration, baking techniques and also new ways of ceramics’ manufacture. The selected creators of siwak in Poland and black ceramics in Lithuania have been discussed. It is worth mentioning that the problem of national identity and ethnic and cultural affiliation of presented regions and continuation of fi ring tradition by young generation has been shown.

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.
