Pueblo Indians from Utah and Colorado – Ancients architects and potters
The Mesa Verde region, located in southwestern Colorado and southeastern Utah, is well known to archaeologists and many tourists because of its beautiful landscape and famous cliff dwellings in the alcoves of the sandstone canyons. These ancient villages were constructed an inhabited during the XIII century A.D. by Pueblo culture. This region was one area where ancient Puebloans developed their culture to a great extent. Today, visible traces of it are well preserved architecture in canyons’ alcoves and niches as well as artifacts, and especially black-on-white pottery. Since 2011 study of the settlement model and socio-cultural changes that took place in Pueblo culture as well as documentation of material culture, mainly pottery is realized by Sand Canyon- Castle Rock Community Archaeological Project, first Polish archaeological project in USA, conducted in the Mesa Verde region, southwestern Colorado.

Synthesis and properties of ecological composites sintered
The subject of research presented in this paper was to try to carry slag from the glass fiber in the composite sintered solid at selected temperature-time parameters. The study used slag derived from the processes of solid waste incineration and a mixture of E and C -glass fi ber. The resulting composites were subjected to microstructural analysis and identification were selected physical properties such as apparent density, open porosity, absorption, and also resistance to ions leaching in a water environment was studied using the method of specimens boiling in distilled water during 60 minutes followed by measurement of water pH. Abrasion resistance was also assessed via friction of the surface by a freely rotating ball during 60 minutes (Calotester).

Synthesis and properties of inorganic pigments based on titanate pyrochlore compounds
New ceramic pigments based on pyrochlore structure Y2Ti1-xMnxO7 (x=0,01-0,1 M) were developed employing solid-state reaction synthesis at high temperature 1400°C. The goal was to determine the infl uence of concentration of chromophore (Mn) and type of mineralizers on the colouring effects of these compounds. The selected pigments were applied into ceramic transparent and opacity glazes as well as into gres mass. Glazes and mass were burned at 1200°C. The results indicated that these pigments can provide red-orange hues and that these compounds are stable in opacity glaze and gres mass.

Outline of the history of stained glass art in Poland

The article presents history of glass art from the beginning of Polish state until present moment describing the most important examples highlighting periods of the greatest development of this craft i.e. Middle Ages and Art Nouveau. The outline contains history of stained glass from the first pieces of stained glass found in Kalisz on which small painted and scratched ornaments were discovered. The composition of used glass is known by chemical analysis what gives us knowledge of contemporary technology. The author discuss also medieval examples of stained glass from Kraków, Toruń, Włocławek and Chełmno. In Modern Times stained glass art lost its importance and is used rarely replaced by other decorative motifs.
