The Possibilities of innovation of the sanitary ceramics body
Čech, Tomáš ; Chudomelka, Josef (referee) ; Sokolář, Radomír (advisor)
The aim of this thesis is to assess the possibility of increasing utility properties shard of sanitary ceramics. Description the current production of sanitary ceramics. Assessing of the impact steatite admixture into existing raw material mixture for the production of sanitary ceramics firing body characteristics (porosity, strength, thermal expansion) using the available scientific literature. Proposition the optimal dose of steatite material into the raw mixture. Evaluation of physical and mechanical properties of the resulting products of this recipe.

Metodika konzervování-restaurování glazované keramiky
Kloužková, Alexandra ; Svobodová, Ljuba ; Dvořáková, Pavla ; Kolářová, Mária ; Kohoutková, Martina ; Randáková, Simona ; Šefců, Radka ; Kloužek, Jaroslav ; Vokáč, Miroslav ; Kubásek, Jiří
Metodika je zaměřena na konzervování-restaurování glazované keramiky s ohledem na stabilitu a pórovitost keramického střepu. Podává ucelený přehled o vhodných postupech pro zpracování materiálu tohoto typu. Obsahuje přehled vhodných metod pro hodnocení stupně poškození (jak střepu, tak glazury), postupy odběru vzorku a metody pro identifikaci chemického a mineralogického složení keramiky i glazury a stability jejich celkového systému. Dále popisuje možnosti čištění, postupy konsolidace, lepení a doplňování chybějících fragmentů a případné retuše střepu i glazury. Obsahuje rovněž zásady pro vhodné uložení těchto předmětů a pro pochopení jednotlivých výsledků jsou uvedeny komentované příklady.

Uranium in historical ceramic glazes: Determination by alpha radiation detection and comparison with other methods
Vopat, Michal ; Goliáš, Viktor (advisor) ; Jelínek, Emil (referee)
In the Czech Republic yellow and ivory glazes with uranium in the Ditmar-Urbach and Terra Teplice companies were manufactured in the pre-war and inter-war period. The production of these glazes took place at the latest since the 1900, the material springs have existed since 1912. Their production ended in 1945. The most suitable method of non-destructive determination of uranium was the measurement of surface alpha activity on planar surfaces by a probe with a ZnS (Ag) scintillator constructed special for this bachelor thesis. Altogether 85 samples, evidence of this production, were measured. To determine the conversion of detected alpha activity to uranium content, an indirect calibration method was chosen to measure uranium content in three types of glazes by WDS analysis. In the studied set, uranium contents ranged from 0.2-2.2 % with the highest frequency ranging from 0.5-0.6 % U. 16 samples of yellow and ivory glazes were without added uranium with contents up to 322 ppm eU. Comparison of uranium contents determined by surface alpha activity measurement with area beta activity confirmed that the glazing does not form a saturated layer for beta radiation. Three types of glazes analyzed by WDS were also measured by XRF. By comparing uranium contents determined by both methods, it was found that...

Ceramics for the First Grade of Primary School
FRAŇKOVÁ, Magdalena
At the beginning of the theoretical part the objects and tasks of the theses are defined. There are also described the teaching methods of project teaching at the primary schools. History of ceramics from all over the world from the Neolithic period is an integral part of the theoretical part. The forming techniques, modeling, glazing and burning techniques are described as well. In the practical part ten ceramics themes to the project teaching at the first grade of primary school are designed. There is a didactic documentation for teachers for each theme.

Painted folk decor on ceramics
MICHNOVÁ, Lenka
The main aim of my master thesis is to describe the development of painted folk decor on ceramics since the arrival of Anabaptism in the Czech Republic. Selected Moravia workshops are used to track the decor development. Another goal of this thesis is to find out whether workshops that produce ceramics and subsequently paint it in the traditional way exit even today. Next part of my thesis is devoted to selected Czech workshops that produce painted ceramics. A presentation consisting of photos is included as well as a literature research.
