History of the Panama canal; its construction and builders . nsported to the nitrating houses, whereit is introduced into nitrators (large ironbowls equipped with appliances for coolingand continually agitating the contents),after which the glycerin is slowly added,great care being exercised during thisoperation to insure against sudden rise oftemperature. A thermometer is locatedat a convenient point in the nitrator toenable the operator to determine changesof temperature during the process of nitra-tion. When the nitration of the glycerin iscomplete the contents of the nitrator, whichnow consist of a mixture of nitroglycerin,water and the excess acid, are conveyedby means of a gutter or trough to the sepa-rating house. Here the .nitroglycerin,which is lighter than the acids, rises to thetop of the mixture, thus facilitating the sep-aration of the liquid explosive from thewaste acids. After separation is completed, the nitro-glycerin is delivered to one or more washtanks and subjected to the purificationtreatment. The finished nitroglycerin is.
