Abstract A method of determining the fudge point of a solution of a compound the solubility of which changes with temperature, which comprises heating to a temperature above the fudge point of the solution a sample cell and an associated reference cell containing a non-crystallizable liquid, such as a silicone oil introducing a sample of the solution into the sample cell, cooling the cells, simultaneously measuring the temperatures of the sample and the liquid while cooling, recording the temperature of the sample at which the temperature curve of the sample diverges from the temperature curve of the liquid, displacing the sample in the sample cell with a fresh sample and reheating the cells. Apparatus for conducting said method is also disclosed.
