On the theory and practice of art-enamelling upon metals
A technical manual on enamelling metals written by Henry Hardinge Cunynghame and published in Westminster by A. Constable in 1899 for craftsmen and studio enamellers. Halftone photographs show cropped hands grinding, pestling and spreading enamel on slabs, alongside workshop views of a belt-driven granite mill and simple line drawings of punches and tools.
