Marmorino Veneziano is a type of plaster or stucco. It is based on calcium oxide and used for interior and exterior wall decorations. Marmorino plaster can be finished via multiple techniques for a variety of matte, satin, and glossy final effects. It was used as far back as Roman times, but was made popular once more during the Renaissance 500 years ago in Venice. Marmorino is made from crushed marble and lime putty, which can be tinted to give a wide range of colours. This can then be applied to make many textures, from polished marble to natural stone effects. Widely used in Italy, its appeal has spread through North America especially, but now worldwide. Because of the hours of workmanship, the pricing places it in the high-end market. However, many examples can be seen in public buildings, bars, restaurants, etc. Its waterproofing and antibacterial qualities as well as visual effects have also made it very desirable for luxury bathrooms, honeymoon bedrooms and other wet areas. Not confined to interior use, it can be seen on the exterior of many buildings to great effect. History Marmorino is well known as a classic Venetian plaster; however, its origins are much older, dating to ancient Roman times. We can see evidence of it today in the villas of Pompeii and in various ancient Roman structures. In addition, it was also written about in Vitruvius's De architectura, a 1st Century B.C. history of Rome. Marmorino was rediscovered centuries later after the discovery of Vitruvio's ancient treatise in the 15th century. This 'new' plaster conformed well to the aesthetic requirements dictated by the classical ideal that in the 15th century had recently become fashionable in the Venetian lagoon area. The first record of work being done with marmorino is a building contract with the nuns of Santa Chiara of Murano in 1473. In this document, it is written that before the marmorino could be applied, the wall had to be prepared with a mortar made of lime and "coccio pesto" (ground terra cotta). This "coccio pesto" was then excavated from tailings of bricks or recycled from old roof tiles. At this point, to better understand the popularity of marmorino in Venetian life, two facts need to be considered. The first is that in a city that extends over water, the transport of sand for making plaster and the disposal of tailings was, and still
