EVAPORATION 373 Scale in Evaporators.—The concentration of the juice which obtains in theevaporators results in certain of the non-sugars becoming insoluble, andbeing deposited as scale on the heating surfaces of the evaporators. Inaddition to the scale formed from bodies originally in solution, there is thatcaused by the introduction of suspended matter due to inef&cient latter deposit is foimd mostly in the first ceU, and the former in the lastcell, where the concentration of the juice is greatest. The scales which arefound in cane sugar houses fall into three classes—siHcate, phosphate, and sul-phate scales, the two former being the most frequent. The quantity of scaleformed is
