temperature at which movement of the specimen is observed is recorded as the pour point. INTRODUCTION In the cloud point experiment‚ waxes will appear and thickens the oil and clogs fuel filter and injectors in engines. The wax also accumulates on the cold surfaces and forms an emulsion with water. The appearances of cloud point determine the first cloud of wax crystals in a liquid when it is cooled.
