Materiality | Get Stoned
Stones seems like a daunting subject to master - aren't there millions of types? - but truthfully when it comes to interior design and construction, you only really need to learn about five of them: granite, marble, limestone, slate, and sandstone. Here are some quick facts:
Granite is an igneous rock (which I definitely had to look up) formed from the cooling of magma. It is typically less expensive than marble and has a more "speckled" appearance created from hot magma melting together different materials into one.
Marble is actually created from layers of shells formed by years of pressure and heat. Marble often has a sort of luminous quality, indicative of the shells that formed it long ago.
Limestone is frequently used in exterior applications (particularly in TX), while travertine (a type of limestone) is more common for interiors.
Slate is softer and more brittle than other stones. Because of this, it can be easily grafted from its original rock and split into thin slabs. It has a noticeably uneven surface, but is still smooth enough to walk on.
Sandstone is, unsurprisingly, a sedimentary rock made of sand. It is often seen installed with its naturally occurring rough edges. Quartzite is also a type of sandstone.
