What is marble?24-Mar-2017
When installing natural stone worktops in your bathroom or kitchen, you will find that there are a number of types of stone from which to choose. Marble has a long history of use in homes and it is both durable and elegant. Of course, like any natural stone, it's helpful to understand what this stone consists of. Its composition will help you understand its strengths and weaknesses which will give you the most realistic expectations.
Firstly, marble is not indestructible. It's tough and it will last a lifetime if it is properly cleaned and maintained. Marble is classified as a metamorphic rock. It forms when limestone is exposed to substantial heat and pressure. It mostly consists of calcite and other clay minerals, pyrite, graphite, iron oxides, and more. When the calcite in the limestone is exposed to heat and pressure, it recrystallizes and a rock mass of interlocking calcite crystals is formed.
Due to its calcium carbonate composition, marble reacts with many acids. While it can be used in a different form to neutralize acids, as a kitchen or bathroom worktop, it's best to steer clear of harsh substances. If a strong substance like bleach spills on your marble surfaces, it can cause significant damage because of the way the stone reacts with the bleach.
The most important thing to remember is that marble is a natural stone and, as such, it is quite porous. In order to prevent stains from penetrating the luxurious surface, it's always a good idea to have your marble worktops sealed upon installation and resealed regularly. Avoid placing hot pots and pans directly on this type of surface and always clean up any spills immediately to maintain that perfect finish.
