Ceramic decorations in industrial space – former “Brauerei Pfeifferhof Carl Scholtz” brewery in Wroclaw (1895–1910)
The former Scholtz brewery building in Wroclaw, constructed around 1893–1895, is a example of a large industrial complex located on the outskirts of the city. The characteristic feature of this building is the spatial layout, architecture and ceramics decorations, which tend to imitate public utility buildings - schools and hospitals, as well as the aesthetics of a brick wall with colorful glazes detail, promoted by the city architect Richard Plüddemann (1885–1910). The Brewery is a typical example of an industrial facility build during the third quater of 19th century, in which the harmony of form and function also has an aesthetic dimension. The article discusses the decorations of facades of the brewery in the context of new technologies in the production of fi ttings and ceramic blocks, as well as presents a selection of templates for brick details between 1864–1900. The aspect of documentation and functioning of the “aesthetics of industry boulding” in the cultural environment, has also been discused.

Thermovisual estimation of the time necessary for drying the two outer layers of a ceramic casting die
The paper evaluates the drying time of two layers (model and constructional) of ceramic casting dies. The slurries were prepared using the aluminum oxide and a colloidal silica-based water binder. The constituents were examined in a scanning electron microscope (SEM), their particle size was determined in a LA-950 analyzer. Then, they were mixed in a mechanical mixer and the properties of the mixtures, such as the temperature, pH, as well as relative and dynamic viscosity were monitored using a thermo-visual camera during five consecutive days. After reaching the ambient temperature, the dies appeared to be fully dehydrated.

Porcelain Garden. Flora in the European Ceramics from the 18th to the 20th Century
The homeland of porcelain is China, where it was produced in the times of the Han Dynasty (206 B.C.–220 A.D.) and improved during the reign of the Tang Dynasty (618–906) and the Song Dynasty (960–1279). In Europe, porcelain appeared only after centuries. The fi rst news came with Marco Polo’s account of his trip to China. In the 16th century objects exported by the Portuguese and the Dutch appeared. They aroused delight among the collectors and provided inspiration. From the 15th century work aimed at inventing European porcelain was undertaken. The success came with the foundation of the Royal porcelain factory in Meissen in 1710, and subsequently with quite a number of manufactories in Vienna, Berlin, Nymphenburg, Ludwigsburg, Sevres and Polish factories in Korzec and Baranówka. Decoration of the early products imitated Chinese and Japanese porcelain, and one of the popular motifs – painted with ceramic enamels – were floral forms, including flowers having symbolic meaning in Oriental art. The article presents the historical development of the forms and types of fl oral motifs used in the decoration of ceramic products. It discusses various sources of inspiration evoked by floristic motifs, and the changing style of decoration, which corresponded to the current artistic styles (from rococo to art deco).

Foam glass obtained on the basis of fly ash from the combustion of biomass
The paper evaluates the possibility of foaming of fly ash resulting from the 100% of the biomass combustion, and kits containing fly ash and packaging glass cullet as well. The selected sets were subjected to the foaming process using experimentally the selected optimum temperature-time parameters. The resulting foam glass was tested for physical properties and microstructure. The study allowed to assess the foaming tendency of both the fly ash, and the material containing the glass cullet. It has been found that the packaging glass cullet and the process temperature have a signifi cant influence on the porous structure formation. The amorphic phase favors the increase in the proportion of closed pores and thus affects the important physical parameters, i.e. the density, porosity, and water absorption.
