Abstract
In this research, the influence of temperature and pressure on the phases formed in a defined glaze are investigated, so an initial batch including silicate, soda, calcium carbonate and boric acid with a defined seger formulation was prepared, and then it was divided into several samples. Some samples were fired at different temperatures and some of them were autoclaved at different pressures. Then the formation of different phases was investigated by X-ray diffraction. Also the microstructure of the samples was observed by scanning electron microscopy. The X-ray diffraction results showed that different phases were formed during firing and autoclaving where the firing process influenced the behavior of the solubility of the materials.

Keywords: Frittic glaze, Solubility.
