Vitreous enamel dials such as on this clock are relatively rare, as they were difficult and expensive to produce. Vitreous enamel or liquid suspension of powdered white glass was applied as a glaze on to a thin metal sheet and then fired at high temperature. This firing, and the difference in expansion between enamel and copper, placed the enamel under stress and made it vulnerable to cracking. To avoid this the dials were made in separate sections which were secured to a brass framework, as may be seen on the present clock. Such dials appear to have been made in London, possibly by Anthony Tregent, whose brother James was Clockmaker to the Prince of Wales. Tregent left the Battersea enamel factory in 1754 to set up on his own. Other makers of enamel dial plates listed in a directory of 1763 are John Brest of Hatton Garden and Francis Gilander of Clerkenwell, although it is probable that they made dials for watches and bracket clocks. See John Robey The Longcase Clock Reference Book, Volume 2, Mayfield Books, 2001, pp.532-534. A comparable dial is also illlustrated in Derek Roberts British Longcase Clocks, Schiffer, 1990, p.220, Fig.320.
