NOLA OSATZEN DA HARRI NATURALA? paisaia harria

Harri naturala etxeetan eta lorategietan gehien erabiltzen den materialetako bat da. Baina inoiz gelditu al zara zure harrizko teila, adreilu edo zorua nondik datozen galdetzen?

Kanpoko hormetarako pilatutako harri sistema natural ederrak

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.

Marmola

Marmola 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.

Kuartzita

Kuartzita Beroaren eta konpresioaren bidez aldatu den hareharritik sortzen da. Harria zuriz dator batez ere, baina kolore marroi, gris edo berdexkekin ere aurki daiteke. Harri natural gogorrenetako bat da, eta aukera bikaina da eraikinen fatxadak, erakusmahaiak eta harri gogorrak behar dituzten beste egituretarako.

Granitoa

Granitoa jatorriz magma (laba) jasan eta mineral ezberdinen eraginez aldatutako harri igneo bat zen. Harria noizbait sumendi-jarduera handia izan duten herrialdeetan aurkitu ohi da, eta kolore askotarikoetan dago eskuragarri, beltza, marroia, gorria, zuria eta tarteko ia kolore guztietan. Granitoa aukera bikaina da sukaldeetarako eta bainugeletarako, bakterioen aurkako ezaugarriengatik.

Kareharria

Kareharria koralak, itsas maskorrak eta beste ozeano bizia elkarrekin konprimitzearen emaitza da. Bi kareharri mota daude, kaltzioz beteta dagoen mota gogorragoa eta magnesio gehiago duen mota bigunagoa. Kare-harri gogorra eraikuntza-industrian erabili ohi da, edo lurrez eta morteroan erabiltzen da iragazgaitza duen kalitateagatik.

Harri urdina

Harri urdina 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.

Arbela

Arbela eskisto eta lokatz-sedimentuak beroaren eta presioaren bidez aldatu zirenean sortu zen. Beltza, morea, urdina, berdea eta grisa koloretan eskuragarri, arbela estalkietarako aukera ezaguna bihurtu da, mehe moztu eta tenperatura hotzak jasan ditzakeelako kalte minimoekin. Arbela ere askotan erabiltzen da zoruko baldosa gisa, bere izaera iraunkorragatik.

Trabertinoa

Trabertinoa 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.
