The shelf life of ceramic tableware is generally around 3-5 years. This number is mainly based on the fact that the ceramic material, due to long-term use, wear and tear, and cleaning, may become rough on the surface, resulting in cracks, etc., which may become a breeding ground for bacteria. However, the actual shelf life is also affected by a variety of factors such as production process, frequency of use, and cleaning methods.
I. Shelf Life of Ceramic Tableware
Ceramic tableware, with its unique texture and durability, is deeply loved by people. However, like other items, ceramic tableware also has its service life. So, how long is the shelf life of ceramic tableware? Generally speaking, the shelf life of ceramic tableware is around 3-5 years. This time range mainly considers that during long-term use, the ceramic material will gradually become rough on the surface due to wear and tear and cleaning, and may even crack. These minor damages not only affect the appearance of the tableware, but may also become a breeding ground for bacteria, posing a potential threat to people's health.

II. Factors Affecting Shelf Life
Of course, the actual shelf life of ceramic tableware is not fixed, but is affected by many factors. First, the manufacturing process is a key factor. High-temperature firing process can effectively reduce microorganisms and harmful substances in ceramics, increase its sealing and wear resistance, thereby extending its service life. Low-temperature firing process, however, may lead to cracking and deformation of ceramics, shortening its shelf life. Second, the frequency of use and cleaning methods will also affect the life of ceramic tableware. Frequent use and improper cleaning will accelerate the wear of the ceramic surface, shortening its shelf life.
