Coloring Mechanism on Copper-Red Glaze

ABSTRACT

The influence of CaO, BaO, $CuCO_3$.$Cu(OH)_2$.$H_2O$ and the ratio of $Al_2O_3$/$SiO_2$ on the color of copper red glaze has been studied under reducing atmosphere. Basic glaze formula was chosen by pre-experiment. Specimen was sintered in oxidizing atmosphere up to 90$0^{circ}C$ and later reducing atmo-sphere to 128$0^{circ}C$ Main analytical instruments used are Esca and Scanning Electonic Microscope. The basic glaze formula of stable copper-red-glaze was found to be ;
