GENERAL COMMENT
The use of freeze-point cells embodies one of nature's simplest and most predictable
phenomena. However, the technique (requiring association of cells with other
equipment) involves subtlety and operator sensitivity. Before relying upon
measurements made in them, the operator should perform enough freezes to become
familiar with the cell, furnace, control, monitoring thermometer and readout (as a
system) to ensure that the melt is clearly identifiable and sufficiently consistent.
