A Frost-resisting Preparation. Autocar 28:11:14 THE sharp snap of frost which we have already experienced may have caught some motorists napping, but those who are wise will have taken the necessary precautions to guard against any such ravages upon the cooling systems of their cars. Apart from the heating of the motor house, which in some, indeed in many, cases is almost impracticable, the motorist may use a non-freezing or frost-resisting preparation for mixing with the cooling water in order to prevent cracked cylinders and other damage incidental to the depression of the thermometer. One of the latest of these preparations, the outcome of the most recent experiment and research, is known as "Aglace," and is sold by Messrs. Brown Bros., Ltd., Great Eastern Street, London, E.C. It is adapted for use, not only in motor car radiators, but in all kinds of water heating apparatus liable to burst or become disabled by frost. Amongst the claims made for it are the following: that, while preventing the water from freezing, it conveys heat perfectly and preserves the containing metal from corrosion, so that the water-circulating fittings are unaffected; does not deteriorate by use, so that it can be used over and over again; does not evaporate, so that wastage from this cause may be made up with water. The composition, which is inexpensive, is sold in a concentrated form, so that one gallon of it, mixed by stirring with two gallons of water, is sufficient to protect any water-circulating system against twenty degrees of frost—a severity very rarely experienced in this country—while smaller proportions will serve for less severe conditions, the following being the requisite quantities of Aglace and water respectively recommended for frosts of varying degrees of severity: 5° of frost require one-third of a gallon of Aglace to three gallons of water; 10° of frost require two-thirds of a gallon to three gallons of water; and 15° of frost require one gallon to three gallons of water. | ||
