HVORDAN FORMES NATURSTEN? landskabssten

Natursten er et af de mest brugte materialer, der bruges i hjem og haver. Men har du nogensinde stoppet op med at spekulere på, hvor netop dine stenfliser, mursten eller gulvbelægning er kommet fra?

Natural stone was created thousands of years ago when the Earth was just a ball of mineral gases. As these gases began to cool down, they compressed and solidified to form the world we know today. It was during this process that natural stone was formed – the type of stone created depends on what type of minerals were combined at that time. This was a slow process that occurred over millions of years. As the Earth began to settle, many of these seams of stone were gradually pushed to the surface by heat and pressure, creating the large formations we see today.

Stone can come from anywhere in the world, and the type of stone is determined by its origins. There are quarries in America, Mexico, Canada, Italy, Turkey, Australia, and Brazil, as well as many other countries around the globe. Some countries have multiple natural stone quarries, whilst others only have a few. Let’s look in closer detail at where particular stones originate and how they were formed.

Marmor

Marmor is the result of limestone that has been altered through heat and pressure. It’s a versatile stone that can be used on virtually anything – statues, stairs, walls, bathrooms, counter tops, and more. Usually seen in white, marble is also common in black and grey tints, and has great weather endurance.

Kvartsit

Kvartsit stammer fra sandsten, der er blevet ændret gennem varme og kompression. Stenen kommer hovedsageligt i hvide farver, men kan også findes med brune, grå eller grønlige nuancer. Det er en af ​​de hårdeste naturstenstyper, hvilket gør den til et fremragende valg til bygning af facader, bordplader og andre strukturer, der kræver kraftige sten.

Granit

Granit var oprindeligt en magmatisk sten, der var blevet udsat for magma (lava) og ændret gennem eksponeringen for forskellige mineraler. Stenen findes almindeligvis i lande, der har oplevet høj vulkansk aktivitet på et tidspunkt, og fås i et stort udvalg af farver fra sort, brun, rød, hvid og næsten alle farverne derimellem. Granit er en god mulighed for køkkener og badeværelser på grund af dens antibakterielle egenskaber.

Kalksten

Kalksten er resultatet af sammenpresningen af ​​koraller, muslingeskaller og andet havliv. Der er to typer kalksten, en hårdere type, der er fuld af calcium, og en blødere type med mere magnesium. Hård kalksten bruges ofte i byggebranchen, eller formales og bruges i mørtel på grund af dens vandtætte kvalitet.

Blåsten

Blåsten is sometimes referred to as basalt, and is one of the most common natural stones around the world. Bluestone forms through the alteration of lava, and because of this, is one of the closest stones to the Earth’s surface. Basalt is generally darker in colour, and is used as house roofing and floor tiles because of its hard texture.

Skifer

Skifer blev skabt, da skifer- og mudderstenssedimenter blev ændret gennem varme og tryk. Tilgængelig i farver fra sort, lilla, blå, grøn og grå, er skifer blevet et populært valg til tagdækning, da det kan skæres tyndt og modstå kolde temperaturer med minimal skade. Skifer bliver også ofte brugt som gulvfliser på grund af sin varige natur.

Travertin

Travertin is created when floodwaters wash through limestone, leaving mineral deposits throughout. As it dries out, the extra minerals solidify to gradually create a much denser material called travertine. This stone is good as a replacement for marble or granite, as it’s much lighter and easier to work with, yet still durable. For this reason travertine is often used on floors or walls, and is estimated to last around fifty years if maintained regularly.
