One. Can a ceramic cup with cracks still be used?
If the crack is very shallow, the ceramic cup can still be used. However, I recommend that everyone replace the ceramic cup as soon as possible, as cracks can harbor bacteria and microorganisms. Using such a cup is unhealthy. Additionally, the longer a cup is used, the larger the cracks will become, increasing the risk of breakage, which is unsafe.
If the cracks are very large, it is recommended to simply discard the existing cup and purchase a new one.
Can I use hot water to repair cracked ceramic cups?
No. When cracks appear on ceramic cups, do not use them to heat or drink hot water. Heating such cups can cause uneven temperature distribution, which can easily lead to breakage, posing a significant safety hazard.
Three. How to use ceramic cups to avoid cracking
1、Hand-painted ceramic cups, ceramic tableware, and ceramic gifts are fragile items. When storing, pay special attention to protecting them from vibration, pressure, and impact. Avoid handling them with sweaty hands; wearing gloves is recommended.
2. Newly purchased high-temperature glazed porcelain should be soaked in clean water for one hour, followed by cleaning with dish soap to remove surface oil. After drying with a towel, place the porcelain in a box with foam padding to prevent damage from impact.
3. Ceramic cups, bottles, jars, and vases are typically formed by joining two segments together, from bottom to top. When moving them, you should not lift the upper part of the object with one hand. The correct method is to hold the neck with one hand and support the bottom with the other. Some bottles and jars with double handles should not be lifted only by the handles, as this could cause them to break or damage.
