Sandstone is predominantly made up of particles of quartz that have been eroded from other rocks, often granite. These particles are carried down streams and rivers and deposited. Natural minerals occur in the water and glue the particles together. Time and the weight of other materials on top compacts the sand to form the stone. Fossilisation is also a regular occurrence. The finished tiles are particularly suited for large slabs and for use both inside and outside.
Travertine is a form of limestone deposited by mineral springs, especially around hot springs. It is a hard, durable material (used to build the Coliseum in Rome) but is characterised by holes throughout the stone and usually exists in the following popular colours: White, Cream, Beige and Brown. Yellow, Red and in particular Silver Travertine are gaining in popularity. Travertine tiles are extremely popular due to the available of a wide variety of sizes and finishes such as Honed and Filled 305x305mm – 305x457mm – 406x406mm – 305x610mm – 406x610mm – 610x610mm – 610x915mm / Tumbled 100x100mm – 100x200mm – 200x200mm – 305x305mm – 406x610mm – 610x610mm – 610x915mm / Unfilled and Brushed 305x305mm – 406x406mm – 305x610mm – 406x610mm – 610x610mm / Chipped or Pillow edged 406x406mm – 406x610mm – 610x610mm – 610x915mm .
The vast majority of our travertine comes from quarries in Turkey
Limestone consists mainly of calcium carbonate that was formed on the bottom of shallow lakes and seas, deposited as loose particles of shells, or formed chemically by the action of acidic water containing carbon dioxide. This slightly dissolves the calcium carbonate that is already present, which then reforms by binding onto particles of sand or shell. Over time these beds build up, are duplicated, and become further compacted by the weight and/or pressure caused by movement of the earth¹s crust. Minerals, often oxides of iron, help to decide the various colours of stone available in all shades of white, black, grey, beige, cream and yellow.
Marble is a metamorphic rock composed mainly of calcite or dolomite crystals. The crystal-like texture is the result of limestone being changed by heat and pressure. Marbles range in colour from white to black, with many varieties of colours in between.
Granite is an igneous rock made up of quartz, feldspar and mica. It is molten rock that has solidified under pressure. It is available in many colours ranging from Black to White with a multitude of colours in-between A very hard material, Granite is excellent for flooring which is subjected to heavy traffic.
Slate is another metamorphic rock formed when sedimentary rock, typically shale, is subjected to great pressure. Slate can be split into thin layers. The minerals within the rock re-orientate themselves to be at right angles to the source of the pressure, and so do the planes of easy cleavage. Our slate tiles comes from China, India and Brazil and are available in a number of colours including Multi-colour, Black and Grey
Basalt is an igneous rock, basically solidified magna or lava flows. Some basalts are compact; some have small holes caused by volcanic gas bubbles. Basalt is usually dark in colour.
