Limestone is sedimentary rock consisting mostly of marine creatures and sediments of organic material such as skeletons and shells. This material settles to the bottom of the water and over millions of years solidify into solid rock.
Limestone is a beautiful stone and is available in many different colours and shades ranging from white, cream, tones of blues, greys, tans and even dark blacks which occurs when there is a high content of organic material. When yellows and browns are prominent there is a high content of iron oxides. Although there tends to be a lot of veining, streaking and speckling on the surface of the tiles, this just adds to its unique appearance. Strong, hard wearing and sturdy, when properly sealed, Limestone can be used to enhance the look of any room in your home and is currently the Interior Designers’ stone of choice.
Travertine is a compacted form of limestone that forms in rivers and especially in geothermal hot springs or geysers by minerals dissolving in water and then being deposited on the earth’s surface via rivers and natural springs. It comes in many different natural colours including ivory, beige, walnut, Brown and gold. Iron compounds or other organic impurities create the warm colours of travertine and it often has bands of vibrant colour running through it caused by chemicals becoming trapped in the stone as it forms. These colours appear as banded lines in the face of the stone. Cross cut style is that very popular cutting style. Colour shades and mineral marking appearance is that make these stone slabs popular since Roman time. Vein cut also coming back
Travertine has a layered appearance and pitted holes (air pockets) which occur naturally from water flow action. These holes in the travertine can be filled in at the factory or left unfilled allowing for a selected colour grout to be used to fill or simply leave unfilled on the walls.
Marble is formed from limestone with the heat and pressure over millions of years in the earth’s crust. These pressures or forces cause the limestone to change in texture to a hard, compact, dense, fine grained stone capable of taking a shining polish.
Minerals that result from impurities give marble a wide variety of colours.
Marble can have six or more major finishes, polished (shiny), honed (matte), tumbled and brushed (textured surfaces). Bush hammered, Sandblasted. The polished and honed surfaces are flat and smooth, while the brushed and tumbled surfaces are textured and aged look. Bush hammering and sandblasting would give textured / grip surface. The polished surface is the shiniest with high reflection, while the tumbled surface is more natural reflecting the least amount of light. The tumbling process gives the stone an aged appearance, achieved by placing the travertine into a large vat with abrasives and sand which then gets shaken or ‘tumbled’. A soft textured appearance is achieved by brushing with coarse wire all over the tiles after the honing process to take away all sharp edges from the surface of the tiles and corners
Travertine is one of the most frequently used stones in modern architecture. It is a commonly use for paving patios, garden paths, façades, external wall cladding, flooring, showers, wall coverings, counter tops, steps and stairs.
ABOUT SANDSTONE SLABS & TILES
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) mineral particles or rock fragments.
Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth’s surface, as seen in Bowen’s reaction series. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions.
Our York grey and York blend sandstones contain high volume of quartz that makes them durable that is why very popular in construction industry
