Ceramics are generally considered healthier than glass when it comes to food and drink containers. This is primarily due to the fact that ceramics are less likely to leach harmful chemicals into food and beverages compared to glass. While both materials are non-reactive and do not leach lead, ceramics have a lower risk of chipping or breaking, which can lead to sharp edges and potential health hazards. Additionally, ceramics can be glazed with non-toxic materials, further reducing the risk of chemical leaching.

According to a study published in the Journal of Environmental Science and Technology, ceramics have a lower leach rate of heavy metals compared to glass. The study found that ceramics leached less than 1% of the heavy metals tested, while glass leached up to 10%. This is significant because heavy metals such as lead and cadmium can be toxic to human health if ingested in high concentrations. Furthermore, ceramics are more resistant to thermal shock, meaning they are less likely to crack or break when exposed to sudden temperature changes, which can occur when hot liquids are poured into them. This reduces the risk of sharp edges and potential cuts.

Glass, on the other hand, while durable, is more susceptible to chipping and breaking, especially when subjected to thermal stress. When glass breaks, it can create sharp edges that pose a risk of injury. Additionally, while glass is non-reactive and does not leach lead, it can still leach other minerals such as lithium, sodium, and potassium, which, while not as toxic as heavy metals, can still affect the taste and quality of food and beverages.

In conclusion, ceramics are generally considered healthier than glass for food and drink containers due to their lower risk of leaching harmful chemicals, resistance to thermal shock, and reduced likelihood of chipping or breaking. This makes ceramics a safer and more durable choice for everyday use.
