Marble is created when the sedimentary stone (limestone or travertine) is exposed to heat and pressure over a long period of time. The stone undergoes a metamorphosis, it recrystallizes and becomes denser and harder. The recrystallization allows the marble to take a nice and beautiful polish finish during fabrication.

4.Procedures of Compressed Marble. This is the very basic step-by-step process of making compressed marble: (1)Selected marble boulders are crushed and sieved into various sizes. (2)Marble granules are mixed with specially formulated polyester resin and compacted under vacuum by vibro-compression technology.

However, since most natural marble is quarried overseas, it does require significant transport resources and energy to get the slabs from the quarry to the end user. Engineered marble, on the other hand, has a much higher embodied energy. It also requires more chemical inputs during the manufacturing process.

Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. In its pure form, marble is a white stone with a crystalline and sugary appearance, consisting of calcium carbonate (CaCO 3).Usually, marble contains other minerals, including quartz, graphite, pyrite, and iron oxides.These minerals can give marble a pink, brown, gray, green, or variegated coloration.

Pure white marble is the result of metamorphism of a very pure (silicate-poor) limestone or dolomite protolith. The characteristic swirls and veins of many colored marble varieties are usually due to various mineral impurities such as clay, silt, sand, iron oxides, or chert which were originally present as grains or layers in the limestone.

The most significant difference between granite and marble is its absorbency. The marble is laxer and more absorbent than granite. Granite, whose crystalline structure makes it more resistant to staining, abrasion, and discolouration, is, in fact, the hardest of all-natural stones. It may be damaged by cleaning liquids.
