对于易于结晶的玻璃组合物，粘度数据的差距在玻璃化转变温度和液相线温度之间扩展。或者，使用差示扫描量热法 (DSC) 来计算粘度，因为 DSC 实验中的冷却速率和假想温度下的剪切粘度都通过恒定的位移因子相关。然而，冷却速度低（
A gap in viscosity data spreads between glass transition and liquidus temperature for glass compositions, which are prone to crystallization. Alternatively, differential scanning calorimetry (DSC) is used to calculate viscosity as both the cooling rate in a DSC experiment and the shear viscosity at the fictive temperature are related by a constant shift factor. However, the low cooling rate (
