The Experimental of Low Temperature Color Slip for Decorative on Earthenware Body.

摘要

The purpose of the study was to investigate the effects of dolomite body, frit and potassium feldspar on the properties of color slip for decorative method of color slip on earthen ware production. The chemical composition of raw material was analyzed by X-ray fluorescence(XRF). The experiment started with triaxial blend of dolomite body, frit and potassium feldspar in the defined ratio and then to painting of color slips on specimen. After that, firing specimens at 950°C in oxidation atmosphere. Finally, the specimens were tested microstructure and physical properties. The results showed that the ratio of 50% dolomite body, 40% frit and 10% potassium feldspar were optimum properties for decorative on earthenware body. In color slip consisting of blue color added cobalt oxide 1 wt% ,green colors added chromic oxide 10 wt% , gray color added manganese oxide 10 wt% ,yellow color added stain 2225 10 wt% and hazel color added ferric oxide 2 wt%.
