Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite.

Under the conditions of metamorphism, the calcite in the limestone recrystallises to form a rock that is a mass of interlocking calcite crystals. A related rock, dolomitic marble, is produced when dolostone is subjected to heat and pressure.

Marble is often used for sculpture and as a building material, especially for interior areas. This material has been used in construction for thousands of years and was widely the prefered product used by Greek and Roman architects.

Marble occurs in large deposits that can be hundreds of feet thick and geographically extensive. This allows it to be economically mined on a large scale, with some mines and quarries producing millions of tons per year.

The benefit of using Marble is the vast amounts of colours that are available. From reds to greens, whites and blues. On commercial projects, Marble is generally seen as a natural stone used for internal cladding. However, due to the variation of its physical make-up throughout different types, this natural stone must be rigorously checked before being installed to make sure that it is fit for purpose. Here at PMJ Masonry, we have experts on hand to guide you through the process.
