Glass transition temperatures (T g ) determined at high rates of heating or cooling are essential for applications involving stress relief during cooling from firing of glass‐to‐metal seals and dental restorations. The measurement of T g at heating rates as high as 600°C min −1 is reported. These high‐rate data, when combined with previously reported low‐rate (≤20°C min ‐1 ) values, indicate that the Arrhenius‐type relation between T g and heating or cooling rate is maintained into the high‐rate regime.
