چکیده    Crystalline glaze is one of the most important artistic glaze types to have visual effect in art ceramic field. it has micro or macro crystals inside or on the surface of glass phases where macro crystals occur being embedded inside the glaze and micro ones form as bunches on the glaze surface. the smallest element forming these bunches is called core,coming together in melted glaze and forming macro crystals. the glaze has the elements to improve crystallization in the primary mixture. after the development of the mixture,glaze crystallized slowly. crystals can be formed in the same or different colours. this study is intended to investigate the effect of zno addition on crystalline formation and development inside the frit mixtures prepared in various ratios. the crystalline developments were inspected and defined with characterization techniques in the best crystal mixture. xrd phase analysis method was used to analyze the phase development of frit compositions and glaze applications. crystals were visualized by polarized optical microscope,and microstructural analyses were done with sem-edx. willemite crystals are formed during glaze firing cycles instead of frit preparation step. successful crystal glaze surfaces are obtained by fritted recipes of zno-na2o-sio2 (zns) and zno-na2o-sio2-al2o3 (znsa) glaze systems.
