ABSTRACT

This study was conducted to study the influence of Co and Fe on the color of glaze and diopside crystals inthe diopside crystal glaze empirically produced and used by ceramic artists, in case of adding Co3O4 and Fe2O3. As aresult, the color of glaze was blue when Co3O4 was added to the diopside crystal glaze and the diopside crystals appearedpastel violet with Co included. When Fe2O3 was added to the diopside crystal glaze, the color of glaze appeared brownand the color of diopside crystals was goldenrod with Fe included. The crystals precipitated on the surface of diopsideconsisted of diopside crystals and diopside precursors. With longer retention time, the amount of diopside precursorsdecreased and the amount of diopside crystals increased. Also, Co was more easily included by the diopside crystals thanFe was and crystallizability of dispside was improved in case of including Co. Including Fe lowered peak intensity ofproperties and partially dissolved the diopside crystals.
