Book excerpt: Excerpt from Materials and Methods Used in the Manufacture of Enameled Cast-Iron Wares It is the purpose of this paper to deal with the materials and methods employed in the manufacture of enameled cast-iron ware. In order that more general information may be available regarding the raw materials used in the compounding of enamels, considerable attention is given to the sources and methods of preparation of these materials, as well as to their properties and effects when introduced into the enamel composition. Methods of calculating enamel formulas and examples of the compositions of enamels of various types are given. The defects in enamels, their causes, and the remedies to be employed in overcoming them are discussed from both the theoretical and practical standpoints. Manufacturing methods and equipment used in compounding the enamels, making and preparing the castings, and applying the enamels are also discussed. This treatise deals with the enameling of cast iron by the dry, or American, process. In this method of manufacture, the thor oughly cleaned casting is painted with a suspension in water of powdered glass, clay, and other materials. This suspension is known as the ground coat. The casting is then heated until the ground coat is thoroughly fused, forming an extremely thin layer of transparent glass on the casting. The piece of ware is with drawn from the furnace and immediately coated, by means of long-handled sieves, with a layer of opaque, white, powdered glass, known as the cover-coat enamel. Next, the casting is returned to the furnace for a couple of minutes during which the cover-coat enamel fuses to a smooth layer. Two such layers of cover coat are usually applied, giving a total thickness of from 31; to 337 of an inch. The treatise does not deal with the methods of enameling cast iron by the wet process, in which a relatively thin cover coat is applied to a thick and only partially fused opaque ground coat.
