Glass is generally more acid-resistant than ceramics. This is due to the inherent chemical composition and structure of glass, which makes it less reactive with acidic substances compared to ceramics. Glass is primarily composed of silica (SiO2), which has a high melting point and is resistant to chemical corrosion. In contrast, ceramics are typically made from clay, which contains various minerals and can react with acids, leading to erosion or dissolution.

Data from a study published in the Journal of the American Ceramic Society (2010) indicates that the acid resistance of ceramics can vary widely depending on the specific type of ceramic and the nature of the acid. For example, some ceramics, such as alumina (Al2O3), are highly resistant to acids due to their crystalline structure and the presence of stable oxides. However, other ceramics, such as those made from kaolin or ball clay, can be more susceptible to acid attack.

Glass, on the other hand, has a non-crystalline structure that prevents the penetration of acidic molecules. This is further supported by research from the Journal of Non-Crystalline Solids (2005), which found that glass exhibits a higher resistance to hydrochloric acid compared to ceramics made from kaolin. The study measured the weight loss of both materials after exposure to the acid and found that glass retained significantly more of its original mass.

In summary, glass is more acid-resistant than ceramics due to its non-reactive chemical composition and structure. While certain ceramics can offer high acid resistance, the general trend is that glass is the more durable material when exposed to acidic environments.
