Scagliola (from the Italian scaglia, meaning "chips"), is an artificial way of imitating marble and other precious material. It is a decorative building material.
Stucco columns, sculptures, and other architectural elements can be made by scagliola. It came into fashion in 17th-century Tuscany.
Scagliola is a composite substance made from selenite, glue and natural pigments, imitating marble and other hard stones. The material may be veined with colours and stuck on to a core, or patterns may be carved into a prepared scagliola matrix. The pattern is then then filled with the coloured, plaster-like composite. Then it is polished with flax oil for brightness, and wax for protection. The whole thing gives a richness of colour not easy to get in natural marbles.
Notes[change | change source]
- ↑ Stucco is a material used for decoration in buildings. It is made of an aggregate (such as sand) plus a binder (such as lime) plus water. Animal or plant fibres are often added to give it strength. Modern stucco might add acrylics and glass fibres to make it last longer.
- ↑ Selenite is a crystalline form of gypsum, and gypsum is basically a form of calcium sulphate (CaSO4·2H2O)
