This article identifies a set of ideal formulation parameters for high-alumina matte glaze through exploratory experiments and testing validation.The optimal weight percentages of the components are 26 wt% quartz,11 wt% Longquan clay,14 wt% talc,and 7 wt% α-Al2O3.Utilizing an orthogonal experimental method,we systematically evaluated the glaze's colorimetric properties,microhardness,glossiness,and microscopic morphology by combining color difference assessment,hardness testing,and observing with a super-depth microscope.Under high-temperature reduction firing conditions at 1310℃,the resulting samples exhibited exceptional comprehensive performance:microhardness reached 4893.3 HV;their color closely approximated natural white light;they demonstrated good body-glaze bonding;and glossiness was recorded at 26.85 GU—effectively showcasing favorable matte characteristics.This research provides significant theoretical support and practical guidance for the application of high-alumina ceramics while demonstrating their extensive potential in modern ceramic industries.
