Definition the temperature of beginning crystallization of allou (or temperature of the end melting a firm mix)
In temperature began crystallization of allou (or end melting of a firm mix) there will be a temperature appropriate by that isoterm, on which the point of structure it allou gets.
In a fig. the type threecomponent of the diagram of a condition of system with eutetic without double or threefold chemical connections and firm solutions is submitted. In temperature began crystallization of structure and there will be a temperature 14000C, as the point and is on isoterm with this temperature (at same temperature will be finished complete melting of a firm mix of this structure).
If the point of structure gets between two isoterms, that, accepting conditionally, that temperature between them changes on line of dependence (that strictly creating not always correctly), interpolation find temperature appropriate to the given point of structure.
