The many melting point methods can be grouped in different ways: (a) Some methods determine the point of complete melting of all crystalline material; others use a point farther removed from there and are more correctly called softening, slipping or dropping points. (b) Some are only being used for melted fat samples, others for finished products, or both. (c) Some depend on the subjective interpretation of the endpoint by the operator; others use objective indications. (d) Some depend upon manual controls; others employ a certain degree of automation. Especially in this last group, modern instrumentation has shown the way for possible improvements. The use of automatic temperature control, linear heating rates and objective endpoint determinations, as shown in some of the examples given, is an encouraging sign. These methods promise a noticeable improvement in the precision of melting point tests.
