As the temperature drops, lead freezes out until, at 183°C, both tin and lead are freezing. Once everything has solidified, the temperature continues to fall.

WebbHow to build a phase diagram. By cooling alloys from the liquid state and recording their cooling rates, the temperature at which they start to solidify can be determined and then plotted on the phase diagram. If enough experiments are performed over a range of compositions, a start of solidification curve can be plotted onto the phase diagram.
