A glazed ceramic product with crystalline structure gives an artistic effect.  In this study, the effects of calcium carbonate (CaCO3) addition into glaze  batches on the crystallization behavior of crystal glaze were studied.  Samples were fired at different gloss firing temperatures ranging from  1000-1200°C with 1060°C crystallization temperature. Xray diffraction (XRD)  and energy dispersive X-ray spectrometer (EDX) analysis of the phases  identified these crystals as willemite (Zn2SiO4) in the form of spherulites.  Scanning electron microscope (SEM) analysis indicated that willemite crystals  are in the acicular needle like shape. XRD result showed that the intensities  of crystal peaks decreased with the addition of CaCO3 up to 3.0 wt%. However,  there was no willemite crystals formation as the amount of CaCO3 raised to  5.0 wt%. Besides that, the results also indicated that willemite growth  occurs during isothermal holding at crystallization temperature instead of  during cooling from gloss firing temperature
