Two measurements in aluminum crucibles with a hole showed an endothermic effect (boiling) in the temperature range 365-445 °C with an onset temperature between 427.9-433.0 °C. The onset temperature is derived from the intersection of the tangent line with the highest slope of the endothermic peak with the baseline. The DSC run no. 34306 showed a small additional endothermic signal in the temperature range of 375 - 385 °C.
