Two DSC measurements in aluminium crucibles with a hole showed an endothermal effect after the melting in the temperature range of 340 - 380 °C. The onset temperature was derived from the intersection of the tangent line with the highest slope of the endothermal peak with the baseline. No further endothermic or exothermic effects were observed up to the final temperature (500 °C). The mass loss after the DSC measurements amounted to 100 %.
