One. If the ceramic bowl has cracks, can it still be used?
No.
When using ceramic tableware, if scratches appear on ceramic bowls or plates, the glaze on the plate may be exposed. If scratched tableware is used to serve acidic or high-temperature foods, it may release harmful substances such as heavy metals, which can endanger human health.

If substandard or non-compliant ceramic products are used, harmful substances will leach out, and when ingested with food, they can cause chronic poisoning over time. Lead compounds in glazed ceramic products can be dissolved by acids, and when food comes into contact with the surface of tableware, the lead can be dissolved out by organic acids in the food.
Furthermore, the sharp edges at the openings of the porcelain bowls also pose a risk of injury.
Two. What are the specific requirements regarding cracks in ceramic bowls?
1、only a beggar would use a bowl with a hole.
In the past, ceramics were very valuable items, and ceramic bowls were considered a luxury. Ordinary households could not afford them, especially in rural areas, where most people used earthenware bowls, commonly known as clay bowls.
In the past, even ordinary people could not afford porcelain bowls, let alone beggars. They could not even afford earthenware bowls, so they could only collect and use broken bowls with holes. Over time, bowls with holes became a symbol of beggars.
2、Cracks in ceramic bowls can negatively impact business.
"Our ceramic bowls are prone to chipping and cracking during use. While many users choose to continue using bowls with minor imperfections, this practice is considered unfavorable according to Feng Shui principles.
Therefore, any bowls with minor cracks must be discarded properly. When discarding, it's crucial to handle them carefully. First, find a red cloth. Then, place the bowl on the red cloth and wrap it securely. This prevents any negative energy from being released and ensures continued good luck and career success.
