If you are pursuing perfection, please think twice before making a decision. ※Depending on the quality of the soil used, the glazing method, and the firing temperature, the glaze will change in various ways, which is a characteristic of handmade pottery. ※Glaze will produce glaze cracks (flaking), pores, particles, and staining during the firing process. This is a normal phenomenon and does not affect use. ※When unboxing the product, please remember to record it with a video. If you find that the product you purchased is defective, please take a photo to save it and contact us. We will reply to you as soon as possible. ♦ Usage and maintenance methods ※The structural pores of pottery are larger than those of porcelain, which makes it easier to absorb water and absorb colors easily. If you mind eating colors, it is recommended to choose dark-colored products or avoid holding dark-colored foods. Before use, the pottery can be simmered in rice water for 30 minutes to allow the starch to fill the holes of the pottery, which can reduce the color of the pottery. ※Before first use, please wash it with detergent or scald it with hot water before filling it with drinks. After cleaning, wipe it dry or place it in a ventilated place to dry. ※Do not heat rapidly (such as open flames, pour hot water directly into the frozen cup, etc.) to avoid excessive temperature differences that may cause body cracks.
