A ceramic photographic enamel consists of a copper or silver plaque,
which is then enamelled white, and a photographic image is fired on to the surface.
This finished result is understood to be permanent, but the process does not end there.
The plaque is then coated several times with an acid-resisting flux, which protects the photograph
(if the enamel is to be coloured, this is done between the fluxes).
The photo enamelled plaque is then
polished with pumice powder on a motor bob,
which gives the vitramic enamel it's distinctive glossy surface.
An enamel which will stand being polished on a hardwood bob fed with pumice powder at
2000 revolutions per minute should be the last word in permanence, as applied to photography.
