Ceramics are generally harder than glass. This is due to the crystalline structure of ceramics, which allows for stronger atomic bonds and a higher hardness. For instance, the hardness of glass is typically around 5.5 to 6.5 on the Mohs scale, while ceramics can range from 6 to 9. Some ceramics, such as diamond, are even harder than glass, reaching a hardness of 10 on the Mohs scale. The data from the Mohs scale, which is a standard measure of mineral hardness, supports this conclusion.
