H. Ger. smalzjan ; M. H. Ger.smelzen =to smelt (q. v.).] A. As substantive: I. Ordinary Language: 1. Literally: (1) A vitreous, opaque, colored material, tractable in the fire, and used in ornamenting metals; in painting on metals, to be subsequently fired. The art of painting in enamel or with metalline colors, and fixing them by fire, was practiced by the Egyptians and Etruscans on pottery, and pa ed from them to the Greeks and Romans. It was also practiced among the Chinese. Specimens of enameled work are yet extant of early British, Saxon, and Norman manufacture. Enamel is applied to various kinds of pots and pans for stewing and preserving fruit, the flavor of which would be injured by contact with iron, and its wholesomene by being cooked in ve els of bra or copper. The ordinary enamel for the purpose is common gla fused with oxide of lead. This will not resist vinegar and some other acids, and a dangerous poison may be present unsuspected. Articles exposed to the weather are sometimes enameled to preserve them from rusting. This has been done with plowshares, moldboards, water-wheels. (2) That which is enameled; a work of art worked in enamel. (3) A gla y opaque bead obtained by the blow pipe. (4) In the same sense as II. 2. Figuratively: (1) A bright smooth surface, like enamel. "Down from her eyes welled the pearles round, Upon the bright enamel of her face." (2) Glo , polish.. Fairfax. (3) A kind of cosmetic or paint for the face. II. Anat .: The ivory-like crust of the exposed surfaces of the crown of the teeth to the commencement of the roots. It is a delicate cellular wavy network of hexagonal crystalline fibers, with calcareous deposits in the cells, thickest over the top of the crown. B. As adj .: Pertaining to the art of enameling; enameled. enamel-germ, s. Anat.: A down-growth of epithelium, whence comes ultimately the enamel of the teeth. There are common and special enamel-germs. ( Quain .) enamel-kiln, s . Porcelain : The enamel-kiln for firing porcelain which has been bat-printed, that is, printed on the glaze, is made of fired-clay slabs, and is 6 by 3 feet, and feet high, with flues beneath and around. The fireplaces are at the sides, and smoke and flame are excluded from the interior. sin, as; expect. Xenophon, exist. ph = f. IMG:content-0951.png:[blocks in formation] Art : Painting upon metal previously covered with a glazed ground. This kind of painting can only be done in small pieces, and it stands in the same relation to porcelain painting as miniature does to water-color painting. The metals used are gold and copper; the latter is usually gilt; silver is never used, because that metal is liable to blister and otherwise injure the enamel, and bra is of too fusible a quality. For bijouterie an opalized semitransparent ground is laid on, or a transparent one through which the foil may be seen. For painting, an opaque white ground, such as we see on the dial plates of clocks, is placed on the metal. The laying-on and burning-in of this ground is called Enameling (q. v.). The best works of this nature were executed in the twelfth and thirteenth centuries. No course of experiments has hitherto made known the substances of which ancient enamels cobalt. The colors are mixed with spike, oil of lav 1642 material of a thinner quality in several applications. Over the surface thus prepared are laid suc ce ive layers of boiled linseed oil and of the oil mixed with lamp-black and turpentine spread on with a brush. The surface, which has become black and shining, is then varnished with copal and linseed oil with coloring matters. Five coats of varnish are succe ively applied, and the colors are varied at will.

Photog.: A photograph, for the ground of which metal or pottery is used; the image is developed by nitrate of silver until the half-tints are overdone or obscured, and the deep shades are covered with a thick deposit. The heat of the muffle drives off the organic matters, which formed but vehicles, and the fire cleans the image and restores the brilliancy and delicacy. A thin layer of flux fixes the image.
