4 principles
Under different temperature conditions, after a certain period of time, the glazed surface of daily-use ceramic samples will be corroded by chemical test solution, and the color will change to varying degrees:
The color difference of the glaze surface before and after the corrosion of the sample is measured by an instrument; and the color difference within the corrosion cycle is measured according to the internationally recognized color difference judgment criteria:
The maximum value of the glaze color difference ΔEab(max) is evaluated to obtain the grade of the chemical corrosion resistance of the glazed surface of the test sample:
