A similar material to Scagliola, also used to imitate marble, but relying entirely on pigments rather than stone aggregates for effect. Coloured Keene’s cement or gypsum plaster is used, together with animal glue and pigments, if a coloured marble is being copied. Frequently marezzo was cast on smooth sheets of slate or glass to give a polished surface; some polishing with pumice stones then followed. However, as the mould itself creates a reasonably smooth surface, the polishing process is not as lengthy as that for scagliola and thus marezzo is easier to produce. It was sometimes used for small areas of external cladding. Ashurst (1983); Trench (2000). [J. Cassar, R. de Angelis]
