Although some of the more elaborate and advanced holders were of copper or brass, most of them were of iron, the work of local smiths, few of whom made any attempt to decorate what they evidently regarded as strictly utilitarian articles (see Fig. 14). Although rushlights antedated candles, some of the holders were made to answer a dual purpose, and on the same stem or slide as the rushlight holder there was a candle socket, an important feature fully exemplified in Figs. 4 and 5. Candles, Moulds, and Boxes. The collector of household curios does not trouble about the candles; his object is to secure a few candle moulds, candle boxes, and, of course, candlesticks. It may, however, be convenient here to refer to the moulding of candles which was at one time a domestic duty just as it had been to collect rushes and after they were dried dip them in fat, and to make lights which would burn with more or less steadiness. The candles were made from various fats, much of which was accumulated in the kitchen during the processes of cooking, supplemented by other ingredients deemed best for the purpose. The candle moulds or tubes in which wicks were inserted were of varying capacities and ranged from two to a dozen or more. The moulds were dipped in troughs of fat, having been heated sufficiently to melt the fat. The process was by no means new, in that it was used in this country by the Saxons; and at a still earlier period candles were made by the Romans, for among the sundry objects picked up among the uncovered ruins of Herculaneum have been small pieces of candle ends. There was but little advance in the art of candle-making, for the candle, briefly described as a rod of solidified tallow or wax surrounding a wick, remained almost unimproved until the eighteenth century, when spermaceti was introduced, and in more recent years paraffin has been substituted. Candles were hung up by their wicks in bunches until required for use, but those needed for immediate supply were always kept in candle boxes. It is these boxes of copper, brass, and tin which are sought after. The decorated japanned tin boxes are very pleasing, and some of the best, ornamented after the "Chinese style" or painted with little scenes, and rich in gold ornament, especially those made with other japanned wares at Pontypool in South Wales, are desirable acquisitions.
