The subject of my research is glass-crystal ceramic glazes - their design and modifications. As part of my research, I use many methods and techniques that allow measuring the properties and parameters that interest me.

In the present time, my research concerns the following research areas:

A. The influence of variable molar ratios of alkali oxides (Na2O/K2O) and earth alkaline oxides (CaO/MgO) on the structure and properties of raw glass-crystalline glazes.

The role of alkaline and alkaline earth oxides is widely known - they act as fluxes. In this research, we focus on determining how the ratio of these oxides affects the structure, microstructure and technological properties of analyzed glazes obtained in the analyzed oxide systems. The main purpose is to expand knowledge of these oxides, which is valuable during design and modify ceramic glazes for the ceramic industry.

B. The effect of a presence of divalent oxides (BaO, SrO, ZnO, ZrO2) on the structure and properties of raw porcelain glass-crystal glazes.

These oxides are presented in many types of glazes because they have a positive effect on some properties. In the works carried out, glaze compositions are created in that way the amount of the analyzed oxide changes systematically. Consequently, such a procedure gives you the opportunity to notice some relationship between the amount of ingredient and obtained properties. Based on the results, we try to determine the optimal amount of oxide, that will cause obtained the glazes with the best properties.

C. The effect of the addition of color oxides (Fe2O3, Cr2O3, CoO, CuO, NiO) on the structure and surface properties of raw glass-crystalline glaze with a variable molar ratio Na2O/K2O or CaO/MgO.

The last area of scientific interest is colored glazes: kinds of variable ratios of alkali oxides and their effects on the color obtained. The first results of the research gave results that indicate a significant effect of the alkali oxides used, on the addition of a constant amount of coloring oxide. Depends on the molar ratio, it is possible to obtain a surface color in such a way that the natural presence of coloring oxides in natural raw materials will be masked by other crystalline phases present in the glazes' composition. The research also concerns to obtain colored glazes of a specific color intended for firing at an established temperature.
