The loading time and temperature dependences viscoelastic behavior of a soda‐lime‐silicate glass (SLS) were studied by indentation creep experiments. Experiments were conducted in air, water and silicone oil with 15–10 000 s loading times, and temperatures ranging between 100 and 500 K. The indentation size was found to depend much on the loading time and temperature. Hardness was found to decrease significantly with increasing loading time, even at 173 K, and to decrease rapidly with rising temperature, even well below the glass transition temperature ( T g ). Water on the surface of glasses appeared to reduce the hardness and indentation viscosity of the glass.
