Idealized liquid/solid (L/S) equilibrium conditions inside fixed-point cells used in freezing and melting experiments. In freezing experiments, as the solid layer on the crucible wall thickens, its L/S interface approaches the L/S interface of the thin solid layer on the thermometer well. Similarly, in melting experiments, as melting advances, the outer L/S interface approaches the inner L/S interface.
