Optimization of High Temperature Reduced Iron Series Crystal Art Glaze Formula Based on Orthogonal Experiments
This study used orthogonal experiments to quantitatively determine the primary and secondary relationships of the main influencing factors of crystal glaze chemical compostition:K2O+ Na2O,K2O/Na2O,SiO2/Al2O3,SiO2,CaO/MgO,BaO,ZnO and Fe2O3.A iron series crystal art glaze suitable for the firing system of the Jingdezhen shuttle kiln is prepared,addressing issues of foot sticking of the flowing glaze and excessively long time vequired for crystallization and thermal insulation.The crystal glaze with yellow green base color and evenly distributed dark green crystal dots can be obtained when the weight percentage of the glaze is SiO2 68.9％,Al2O3 5.3％,Fe2O3 2.6％,CaO 5.3％,MgO 11.9％,K2O 1.3％,Na2O 2.6％,BaO 0.7％,ZnO 1.3％,TiO2 0.1％,respectively.
