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), otherwise known as calcium carbonate, and usually contains other minerals, such as clay, micas, quartz, pyrite, iron oxides, and graphite.
Dolomite is an anhydrous carbonate of calcium magnesium carbonate (CaMg(CO3)2). This class of stone is closely related to marble and limestone in its’ constituency but has an added mineral to make it uniquely different, namely, Magnesium. While it is considered marble, the addition of the Magnesium in dolomite enhances scratch resistance, heat resistance and staining and etching resistance.
Quartzite is a non-foliated metamorphic rock composed almost entirely of quartz. It forms when a quartz-rich sandstone is altered by the heat, pressure, and chemical activity of metamorphism. Metamorphism recrystallizes the sand grains and the silica cement that binds them together. The result is a network of interlocking quartz grains of incredible strength.
Onyx is naturally formed from calcite in caves around the world when water drips and evaporates from the ends of stalagmites and stalactites. Once it evaporates, it leaves behind traces of minerals and calcium carbonate which causes its intricate bands of varying colors. The bands of color are produced with alternating silica minerals – quartz and morganite – and leave behind bands that lie parallel to one another.
Limestone is a sedimentary stone comprised mostly of decayed fish bones formed at the bottom of an ancient seabed. Over geologic time its Calcium Carbonate grains were compacted together enough to create the stone we know as limestone. Here as well, other mineral inclusions and binders give each limestone variety its unique coloration.
Our SlabSmith technology allows us to overlay the templates of your project on the slabs you select so that you can see exactly how your project pieces will look before they are cut to make sure you get the exact flow, colors, etc. in the areas that you want them.
Once we have this virtual layout the way you want it, this digital information flows seamlessly throughout the entire production process, thanks to our cutting edge technology.
Come visit our showroom where we would be happy to show you our SlabSmith technology, and how it helps us ensure your complete satisfaction.
