As a new product,the silver porcelain cup meets people's characteristic needs and is favored by the market because of its diverse patterns and styles.X-ray fluorescence spectrometry,ICP spectrometry,potentiometric titration,and photomicrography system were used to test and observe the silver porcelain cup in the experiment.The results of the study show that the X-ray fluorescence spectrometry method makes it difficult to obtain accurate detection results due to the thin silver layer on the silver porcelain cup.Potentiometric titration can be opted for detection.Lead is often detected in silver porcelain cups.To reduce the lead content in products,it is recommended to use lead-free glazes.
