Marmorino Veneziano is a type of plaster. It is based on calcium oxide and used for interior and exterior wall decorations. Marmorino is made from crushed marble and lime putty, which can be tinted to give a wide range of colours. Dating back to Roman times and throughout the 14th-16th centuries, this kind of plastering was developed by a young Venetian architect called Andrea Palladio. Venetian plaster is a hard wearing, high gloss surface, characterised by its attractive marble grain.
