To repaint clock dials, all the old paint must first be removed, and the plate cleaned thoroughly from grease. The white ground can be painted with white enamel, obtainable in 3d. and 6d. tins. These enamels dry hard and glossy. The figures may be painted with black enamel, with a fine camel-hair brush. If only a single dial is to be painted, the figures may be spaced out on a piece of paper a little smaller than the dial plate; when this paper is laid upon the dial to be painted, the marks can be easily transferred to the minute circle.
