1. Because “color on glaze” is to draw colorful patterns on the surface of porcelain fired at high temperature, and then fire in a low-temperature kiln to melt the color and glaze together. So try to buy underglaze color porcelain when purchasing a ceramic water cup. If it is glazed porcelain, please don’t choose too fancy ones. Because there are many harmful metals lead and cadmium in the painted pigments, if the glazed water cup is used for a long time, the harmful metal pigments in the water cup will dissolve and follow into the human body, which is likely to cause chronic poisoning. It is recommended that you try to choose a colorless white high-grade water cup or a high-grade water cup without lead glaze.
2. Do not store acidic food, fruit juice, wine, coffee and other beverages in ceramic water cups for a long time. Because the longer the ceramic water cup holds the drink and the higher the temperature, the easier it is to dissolve the lead, which is equivalent to aggravating the toxic and side effects of the dissolved amount of lead.
3. Tap a few times, the sound is crisp and high-quality, and the sound is dull or hoarse, which is inferior.
4. Thin-bodied ceramic products should have a sense of transparency when viewed under sunlight or light, which is thin and light, and has a uniform thickness.
