We have provided a number of answers to Frequently asked Questions relating to our Bespoke Natural Stone products
Q. Can Marble be used in kitchens?
Marble can be, and has been used in many kitchens, but it is not advisable because it is highly reactive to the acids which is contained in many cooking items, such as vinegar, lemons, tomatoes and orange juice. These acids will penetrate the marbles surface and stain or corrode the stone. The shine finish can be restored, but can be a very time consuming and expensive procedure.
Q. What are the different types of stones?
There are four main categories of which stones are identified: SEDIMENTARY, METAMORPHIC, IGNEOUS STONE, and MAN-MADE (Quartz).
SEDIMENTARY rocks are formed from sediments that have settled at the bottom of a lake, sea or ocean, and have been pressurised over millions of years. The sediment comes from eroded rocks carried there by rivers or ice. Also from fossils of sea creatures.
LIMESTONE: composed primarily of calcium carbonate (CaCO3) in the form of the mineral calcite. Varies in colours and most limestones are in Matte/Honed finish as it cannot be polished. Most common colours are Beige, Brown and Grey colour. FOSSILSTONE: Considered a limestone that contains natural fossils such as sea shells and plants.
SANDSTONE: is composed of sand-sized grains of mineral. It also contains a clay cementing material which bonds the sand grains together. Usually formed in light brown, yellow or red colours.
FOSSILSTONE: Considered a limestone that contains natural fossils such as sea shells and plants.
TRAVERTINE: Key characteristics of Travertine stone are the holes within the stone which are caused by carbon dioxide evasion. Travertine often has a fibrous or concentric appearance and exists in white, tan, cream-colored, and even rusty varieties. It is formed by a process of rapid precipitation of calcium carbonate, often at the mouth of a hot spring or in a limestone cave. In the latter, it can form stalactites, stalagmites, and other speleothems. It is frequently used in Italy and elsewhere as a building material. Travertine is a terrestrial sedimentary rock, formed by the precipitation of carbonate minerals from solution in ground and surface waters, and/or geothermally heated hot-springs. Similar (but softer and extremely porous) deposits formed from ambient-temperature water are known as tufa.  wikipedia
METAMORPHIC stone is a result of a transformation of pre-existing rock which was subject to extreme heat and pressure. These physical and/or chemical changes may be a development of a crystalline formation, a texture change, and/or a colour change.
MARBLE: is metamorphosed limestone which is softened from heat and pressure and recrystallize into marble where a form of mineral change has occurred, composed of fairly pure calcite (a crystalline form of calcium carbonate, CaCO3). It is extensively used for bathroom floors and cladding but its uses are endless. Marble can be sourced in many different colours but is usually veined.
SLATE: A fine grained metamorphic stone that by intense heat and pressure. Usually black, grey, or green. Used commonly in fireplaces and fire earths due to its heat resistant properties.
IGNEOUS stones are mainly formed when the earth melts the rock. Molten, or liquid, rock forms (known as magma) which is then cooled and solidified naturally. This type of rock is known as igneous or as known in Latin, ignis meaning fire. Mineral gases and liquids penetrated into the stone and creating new crystalline formations with various colours.
GRANITE: is a very hard, granular, crystalline consisting of Quartz and Feldspar with small amounts of mica, amphiboles and other minerals. All granite has what is called coarse-grained texture, meaning that the individual mineral grains are visible to the naked eye. Granite is favoured in many kitchen worktops/surfaces but is also heavily used in flooring and cladding.
MANMADE QUARTZ or also known as Engineered Quartz, is mostly made of 90-95% natural ground quartz and 5-10% of resins, pigments and colouring. These are all combined and engineered into durable and non-pourus slabs. The strength of engineered quartz makes it naturally resistant to abrasion, scratches, dents, and even acids without the need for sealants. One of the appealing features of engineered quartz is the fact it has such a wide variety of colours, patterns and textures. The engineered stone industry is forever expanding and developing new ways and methods of creating more ‘natural like’ designs.
Q. Where does natural stone come from?
Natural stones are formed when mineral sediments are exposed to millions of years to the earth’s natural heat and pressure. These minerals are the characteristics of natural stone. Natural stones are quarried all over the world but majority supplied from Italy, Spain, India, Greece, Brazil, United States, Mexico, China, Turkey and Portugal.
Q. Will my natural stone look like the samples?
It is not likely. Since natural stone varies from one slab to another, it is unlikely that a sample will represent a like for like of the material. Viewing of the full slab is advised. A sample is only used as an indication of the material it represents.
Q. Can natural stone be used on the exteriors of homes or commercial buildings?
Yes, many natural stones are used for exterior wall cladding, even in extreme weather. Depending on the location, it may be limited to the type of natural stone suitable to be used outdoors.
Q. Why is one material more expensive than another?
There are many factors that contribute to the price; including the quality, supply and demand, transport and many more. The quality of the finest processed marble will have a higher value than the same marble from a lower quality quarry. Even factors such as the rate of the U.S. Dollar will contribute to its price.
Q. Why should I choose a natural stone floor?
Natural stone has its beauty wherever it is used. The fact it is durable and easy to maintain, will leave your floor looking stylish for many years to come. It is very easily maintained with the correct equipment and guidance from Koliqi Marble. The price of natural stone has decreased in the recent years making it a very affordable and luxurious choice.
Q. How do I prevent staining on Natural Stone?
The majority of Natural Stone (with the exception of some Granite and Quartzite) are porous and will absorb almost any form of liquid. Sedimentary stones are the most prone to absorption, the use of a silicone based stone sealant is applied to help prevent staining of the stone. But, even a sealed surface can be stained if the liquid is left for an extensive period. Therefore, all spills should be removed of the surface as soon as possible. Once wiped, the point of contact with the liquid should be cleaned with mild soap and warm water.
Q. Can you give me a quotation on the telephone?
Yes, however it is helpful if you can provide a drawing/sketch of the kitchen. If this is not possible, even just measurements of the area which the counter tops will sit is helpful enough for a quote.
Q. Should my wall units be fitted before you come?
Wall units are not to be fitted if it can be helped. This allows a much easier and safer method to fit the worktop. However in some instances, this can not be helped, for example when you are replacing existing worktops.7
Q. How should I prepare for your arrival?
Your cabinets should all be level and clear of any cables etc. Support for the worktop should be fitted where it is required. This information will be given when the template is taken.8
Q. Can I see the Granite/Quartz/Marble before fitting?
Yes, please view our ‘Stone types’ and simply click ‘Request a Swatch’
Q. Can you get any type of granite?
We offer a bespoke service. If you are looking for something different or unusual we are happy try and meet requests.
Q. Do you do odd shapes/sizes?
Yes, we do offer a bespoke service. Contact us with your idea.
Q. Do you install worktops anywhere in the UK?
We have done for many years and we will continue to do so. Even though we are mostly concentrated in the London region, we will always consider work outside this area.
Q. Can you see the joints?
On some materials, joints can be visible even though our experienced fitters will do their utmost best to minimise visibility of the joint. Some materials, like some Granites, can be more discreet where the joint isnt so visible. We always aim for a 1-2mm joint.
Q. Should we tile the walls before fitting the tops?
No as this should be done after the fitment of the worktops for a more cleaner finish.
Q. Will I need to be there when you install my worktops?
If possible, you should be there to approve your worktop.
Q. Do you offer a templating service?
Yes, we offer a full service from templating to installation.10
Q. What is the difference between and upstand and a splashback?
Upstands are normally 100mm high. Splashbacks are generally the height of the wall units or hob extractor.
Q. Will you plumb in my sink / fit my cooker?
This is the plumbers/electricians job. We will only attach the sink onto the worktop and open a 35mm diameter tap hole for the plumber to use to connect your taps.
Q. Can I just replace my existing worktops?
Yes, many people do. If the kitchen unit are in good condition, there is no need to replace them. The old worktops must be removed and units levelled if required.
Q. How do I best care for my worktops?
In most cases, warm water and soap is all thats needed to maintain the stone. Please view our care and maintenance page for more information.
