GENERAL QUESTIONS

TRAVERTINE

Travertine is unique because it is spread out among the world, so it travels to many different places. With the principal mining points in places like Iran, Italy, Mexico and Turkey, the travertine you see in the shop has probably travelled thousands of miles to reach you.

t’s also prone to etching—a chemical reaction that eats away at the stone—from acidic substances, including wine and other alcohols, vinegar, coffee, tomato juice or sauce, and citrus juices. Bleach and ammonia can also cause etching on travertine.

If the Travertine is installed on concrete and the crack goes through more than one tile in a row, the crack is normally caused by settling. If the Travertine was installed over a plywood sub floor it could mean that there is not enough support or the proper underlay was not used.

In addition to its colour, this material is very recognisable by its fibrous and porous texture. This is partly due to the gas bubbles that are often trapped between the layers of stone, creating spherical hollows, as if they were pores or cavities.

Travertine is often used as a building material. It typically lacks planes of weakness, and its high porosity makes it light in weight for its strength, gives it good thermal and acoustic insulating properties, and makes it relatively easy to work. Dense travertine makes excellent decorative stone when polished.

The Official Reasons Travertine Tile Is So Trendy
Its unique mottled pattern makes it a popular choice among homeowners, and it is available in a wide variety of colors and sizes. Travertine and travertine tiles are a durable material that will last a lifetime and add value to any property. It is typically sourced from hot springs, limestone caves, and quarries.

Also, Travertine tiles and pavers being heat resistant, do not get hot in the sun, and are comfortable to walk on. Their fire resistance means they do not crack and do not need additional safety layers in fireplaces.

Travertine is not as durable as Granite. However, if properly cared for, it lasts an eternity. Sealing is the most effective way to preserve the stone for a long duration. With so many stone options to choose from, homeowners swear by the opulence and style of this natural stone.

Travertine is a natural stone that is similar to limestone. It forms around mineral springs, especially hot springs. Fibrous pores in the stone make travertine different from other popular stones, like granite or marble. These holes mean that travertine absorbs water quickly.

Travertine floors can damage easily, any oily or harsh spills can damage the travertine tiles and penetrate the pores leaving a permanent stain, unreachable by domestic cleaning methods.

In areas prone to dampness, mould can quickly develop in the unfilled holes.” To fill the holes in the tumbled travertine, we recommend using a pre-packaged grout in a complementary colour to the stone.

Rust basically develops on any surface that has iron deposits. Natural stone like travertine and marble have iron deposits in their molecular structure and chemical composition.

Like most natural stone, travertine pavers will not fade — even if they’re always in the full sun. You can’t say the same for most manmade products.
 

We’re happy to report that our durable travertine pavers do well even in drastic temperature conditions. From 100 degrees Fahrenheit in July to freezing winter weather, travertine stone patios look great season after season, year after year

It is a very durable stone, and while it is easier to care for than some types of natural stone, travertine is very heavy, and its porousness requires that you seal the surface regularly. It is not appropriate for all locations. Pros – Travertine looks luminous, attractive, and cool. Installing it in the Kitchen is recommended. Clean it regularly and keep it dry for the best experience. Cons – Travertine Limestones are porous, which makes them vulnerable to stains and scratches.

Travertine gets it color naturally once it’s exposed to extreme temperatures. Travertine becomes white, red, yellow, orange, and brown once the carbonate material aragonite is activated through extremely warm temperatures and precipitation.

It is a natural sedimentary rock that is most often found in Italy but travertine deposits are also common in Turkey, Mexico, Peru, Croatia, Iran and even China. It is also found in the USA but most of the material used there is imported

Travertine is a go to luxury natural stone element for contemporary bespoke interiors, and yet it has a long history that can be traced to ancient Roman architecture including the world renown Colosseum.

Many homeowners love travertine pavers for the fact that they add colour, texture and appeal to their outdoor living areas. This naturally occurring stone is known to last for many years if it has been properly cared for, but it is prone to the development of mold when exposed to excessive moisture.
 

Over time excessive amounts of water can cause Travertine to lose its shine and causes a white chalky looking build-up. The hard water causes this build-up.

The good news: Travertine Pavers can withstand the fluctuations in cold weather and harsh freeze/ thaw climates just as easily as they can endure 100F+ scorching summers in the south.

Take special care to avoid contact with common acidic liquids such as vinegar, wine, fruit juices, coffee and tea – all of which can stain travertine permanently. If travertine comes into contact with any of these liquids, it should be cleaned immediately with a soft damp cloth and neutral soap.
 

MARBLE

Marble is a metamorphic rock that is created as a result of the metamorphosis of a combination of rocks under intense pressure and temperatures. These rocks include calcite, limestone, dolomite and serpentine. The main component of marble is calcium carbonate and contains acidic oxide.

Marble doesn’t hold heat – This is one of the most interesting facts about marble stone. The stone is heat-resistant compared to concrete and wood – which absorbs and holds heat. Marble is used to naturally cool interior spaces in hot climates.

The most common Italian marble is Carrara, named for the region it comes from. “Carrara has a gray field, or background,” says Bruno, “with a light gray veining.” This stone can also tend toward blue-gray, and the patterning is usually soft and feathery.

While marble is quarried in many countries around the world including Greece, USA, India, Iran, Spain, Romania, China, Sweden and even Germany, there is one country which is generally considered the home of the most high-grade and luxurious marble available

Unfortunately yes, they are very prone to heat and when they come into contact with extreme heat, the thermal shock can force cracks in the marble’s surface – permanently damaging them.

Often times, you will find that it feels colder than the other surfaces in your home. This is because the rock conducts heat in a different manner. Its high density and hardness enables heat to transfer from a warm object, like your soles. Heat dissipates fast through marble, too, so the flooring does not feel warm.

Marble rates a 3 on the Mohs hardness scale, and is considered a “soft” stone – hence its common use in sculpture. It’s also a porous stone, so it’s more prone to staining and damage due to harsh cleaning products.

Marbles are used principally for buildings and monuments, interior decoration, statuary, table tops, and novelties. Colour and appearance are their most important qualities.

Marble is a timeless natural stone loved for its eternal beauty and durability. Its homogeneity and softness make it easy to carve which is why it was commonly used in ancient times to create structures and sculptures that later became famous.The longevity of marble has made it the prefered material for construction. Marble is the most convenient and aesthetically pleasing material for use as a kitchen countertop because of its resistance to heat. Elegant and long-lasting, marble was the material of choice for ancient emperors.

Marble is a porous material, which means it can absorb moisture from the air. If moisture gets trapped inside the marble and then freezes due to cold weather conditions, it can expand and cause cracks

One of the biggest concerns of homeowners when it comes to granite and marble for kitchen countertops is porosity. They believed that this encouraged the growth of bacteria. The study discussed above shows that this is not true and that granite and marble, as well as quartz, are food safe and easy to keep that way.

Solid fuel fires Both marble and granite will crack when exposed to high temperatures, such as those of a solid fuel fire.

If exposed to direct sunlight for extended periods, the color of marble can be permanently altered. Over time, sun and light can cause the color of the stone to fade.

Yes, marble is porous. This means it can absorb water and other liquids into tiny holes in its surface.

Perhaps the most well-known weakness of marble is that it is a porous material, which means it absorbs liquids. It is more porous than other common materials such as granite worktops, for example.

Although due to it’s natural foundations, marbles are precisely finite, there is plenty of evidence that the marble beds in this region are so plentiful we may as well consider them infinite.

Marble has been used for centuries in just about every possible interior and exterior application. Artists like this medium because the material is relatively soft and easy to work with when first quarried, but it becomes very hard and dense with age. The material is also available in a variety of shades and patterns.

The Romans first uncovered marble in the town they named Luna. That site is the present-day village of Luni, less than 10 kilometers from the source of the marble used in Richard’s sculptures.

Sealing and Finishing Marble Floors- To avoid damage, deterioration and powdering, marble and other natural stone surfaces need to “breathe”. Therefore, any surface protection must be permeable.

Marble is extremely durable and because of its limited porosity does not absorb large amounts of water. It does, however, absorb some water and, since it is highly reactive when exposed to acids or even mildly acidic rain water, it can suffer substantial deterioration.

Since marble is a natural stone, it is heat resistant up to 350 degrees Fahrenheit. While extended contact with high temperatures can still cause some damage, a well maintained countertop should not be affected by an occasional hot item or short-term exposure to high temperatures.

Marble can develop reddish marks for a variety of reasons, such as spilled red wine, bacteria or moisture that interacts with the iron in the stone.

LIMESTONE

Limestone is extremely durable. It does, however, absorb water and, since it is a carbonate rock, it is highly reactive when exposed to acids or even mildly acidic rain water, and it can suffer substantial deterioration. The most common effect of weathering and erosion is loss of precise detail.

The stone has the unique property of retrograde solubility, meaning that the stone is less soluble in water as the temperature increases. Limestone is also classified as a young marble formed from the consolidation of seashells and sediment.

Although relatively soft, with a Mohs hardness of 2 to 4, dense limestone can have a crushing strength of up to 180 MPa. For comparison, concrete typically has a crushing strength of about 40 MPa. Although limestones show little variability in mineral composition, they show great diversity in texture.

Limestone is a very common sedimentary rock consisting of more than 50% calcium carbonate. Although it occurs in many different forms, its origins can be traced back to either chemical or biochemical processes that occurred in the geological past, often tens to hundreds of millions of years ago.

They already know what makes limestone decay. Chemicals such as sulphur dioxide and nitrogen oxides from air pollution react with the stone to make it dissolve. This sometimes creates a hard, black, gypsum crust on the outside, leaving a soft, crumbly stone underneath.

Limestone (CaCO3) reacts with hydrochloric acid according to the equation CaCO3 + 2 HCl —> CaCl2 + H2O + CO2.

When sulfurous, sulfuric, and nitric acids in polluted air and rain react with the calcite in marble and limestone, the calcite dissolves. In exposed areas of buildings and statues, we see roughened surfaces, removal of material, and loss of carved details.

Limestone is generally less expensive to purchase and install than other natural stones like marble and granite. It is an excellent option for someone who wants the sleek look and feel of natural stone but is on a limited budget.

If exposed to direct sunlight for extended periods, the color of limestone can be permanently altered. Over time, sun and light can cause the color of the stone to fade. Also, surface discoloration can occur when objects placed on top of limestone are left in the same place for long periods.

On the contrary Limestone Pavers deflect light and have a cooling effect. With good insulating properties, the natural stone Pavers do not turn hot in extreme heat. The pores on their surface transfers the heat beneath and tends to remain cool even in extreme heat

Many people don’t know it but limestone is actually one of the most durable of all natural building materials. Limestone is exceptionally weather-resistant and while it does naturally corrode over time, the corrosion is superficial and won’t impact the structural integrity of the structure.

The three leading lime producing countries in the world as of 2022 were China, the United States, and India, with production volumes of 310 million metric tons, 17 million metric tons, and 16 million metric tons, respectively.

It should be frost-proof, so that it’s not affected by the freeze/thaw action, which could ‘blow’ and damage the surface. Very pale limestones tend to be more susceptible than darker ones; they also tend to be less dense/durable, more prone to glare and, of course, show up dirt more easily.

A sawn limestone with no finish that is dense or hard will become slippery when wet. Limestone that is porous should not be used for steps as they fail in the winter when the frost hits them. They tend to fall apart from freezing. It is important to have the correct finish on limestone to give a good slip resistance.

Limestone is a raw material that is used globally in a variety of different ways including construction, agriculture and as industrial materials. Limestone is very common in architecture, especially in Europe and North America.

One of the benefits of liquid limestone is that it is stronger than concrete. Therefore, it will hold up well for years to come.

Carbon dioxide in the air dissolves in rainwater and becomes weakly acidic. This weak “carbonic acid” is able to dissolve limestone as it seeps into cracks and cavities. Over many years, solution of the rock can form spectacular cave systems

GRANITE

  1. Durable Beauty: Granite is a natural stone known for its remarkable durability and timeless beauty, making it a popular choice for countertops, flooring, and more.
  2. Natural Variability: Each granite slab is unique, with intricate patterns and colors formed by nature, ensuring a one-of-a-kind look for your project.
  3. Heat and Scratch Resistance: Granite’s dense composition makes it highly resistant to heat and scratches, providing a reliable surface for cooking and daily activities.
  4. Low Maintenance: Sealed granite is easy to clean and maintain, requiring only regular wiping to keep its lustrous appearance intact.
  5. Versatile Applications: From kitchen surfaces to outdoor spaces, granite’s versatility allows it to enhance both interior and exterior design projects with elegance and durability.

Granite is the oldest igneous rock in the world, believed to have been formed as long as 300 million years ago. For those who’ve forgotten your high school science classes, igneous rocks are formed from cooling lava or magma. Granite is also what’s called a “plutonic” rock, meaning that it forms deep underground.

Granite can be permanently stained if you seal it with a preexisting stain. It can crack when hit by a hard, sharp object like a meat cleaver. Because it’s so heavy, granite often requires additional structural support with spans and cantilevers.

Granite is an igneous rock, which means it was formed deep within the earth from volcanic magma as it slowly cooled.

The word “granite” comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a completely crystalline rock.

Granite is generally considered the strongest and most durable commercial stone type. Most of the minerals within granite are hard giving the stone a high abrasion resistance. Granite is also highly acid resistant making it a great choice for kitchen bench tops, toilet floors and throughout entertaining areas.

Granite is famous for its natural ability to resist moisture. In fact, that’s one of the reasons it’s such a good choice for counters. It has a natural water resistance that helps protect it. However, it isn’t water-proof.

Granite is naturally heat resistant, and heat damage would occur only if the granite was heated unevenly. So briefly putting a hot pan down on your granite countertop isn’t going to cause long-term damage. That said, we don’t recommend putting hot pans on granite countertops — not for the granite’s sake but for yours.

Sharp Knives. …
Highly Pigmented Liquids. …
Acidic or Abrasive Cleaners. …
Raw Meats. …
People.

The beauty of natural granite is an important consideration, but so is its stain-resistant functionality. And you won’t have to worry about drink spills staining your granite as long as you wipe up messes as they happen.

As a result of all of Mother Nature’s work, granite is extremely dense. This density is what makes granite so heavy; granite weighs in at about 166.5 lbs per cubic foot with the darker denser colored granites heavier than lighter granites. Concrete weighs about 150 pounds per cubic foot.

Granite is currently known only on Earth where it forms a major part of continental crust. Granite occurs as relatively small, less than 100 km² stock-like masses and as large batholiths often associated with orogenic mountain ranges and is frequently of great extent.

Granite has a natural temperature because it is a natural stone or material. Most of the time, it will be cooler to the touch but the granite sustains the room temperature and radiates the temperature throughout the kitchen, bathroom, or whichever room the granite countertop is located in.

In many cases the granite looks dull or cloudy. So, granite countertops don’t exactly fade or change in tone, they are often coated with substances that make the surface appear dull. Technically, the shine is still in there.

Natural granite stone will not fade or yellow in the sun. Granite slabs treated with dyes or resins can fade or darken over time. Avoid this problem by working with a reputable supplier and sealing your countertops regularly.

One thing to keep in mind: granite is naturally UV resistant, but if it has been treated with color-enhancing resins, these resins will fade with prolonged exposure to the sun. Granite is affordable, wonderfully durable and relatively easy to repair if it should suffer a chip or crack.

Found in mountain ranges throughout the world, granite is the result of the eruption and cooling of volcanoes. Over time, these materials harden into an extremely tough and durable material.

China (107M tonnes) remains the largest granite, sandstone, and other building stone producing country worldwide, comprising approx. 31% of the total volume.

Granite is somewhat common on Earth, and its formation is generally driven by water and plate tectonics, which aid in creating large melt bodies below the Earth’s surface. However, granites are extremely rare on the Moon, which lacks these processes.

Granite is one of the best choices of natural stones to use in outdoor areas. It is incredibly resistant and easy to maintain. As long as you seal it, it will be protected against the cold and it won’t crack.

No, but it can discolor it so you want to be cautious with especially hard water on your granite countertops.

Diamond is the hardest and rates a 10, while granite is the toughest natural stone at 6. Limestone comes in at 3 as does its metamorphic counterpart, marble. Softer stone is easier to dress or carve but does not wear or weather quite as well as harder stone.

CARE & MAINTENANCE

Regularly dust the surfaces with a dry, untreated feather duster, or with a cloth lightly dampened in soapy water. Dust and dirt are abrasive and can damage your stone over time. In addition, daily maintenance prevents cleaning with more aggressive products from becoming necessary.

Mild dish soap.
Flour.
Hydrogen peroxide.
Commercial natural stone cleaner.
Microfiber cloth.

With stone, once its laid, the only maintenance required is to keep is clean. Over the long term, maintenance with stone is much less than timber.

It’s essential to only use cleaners which are appropriate for natural stone surfaces. This means avoiding using vinegar. Stones like limestone, marble, or travertine will react to vinegar because it’s an acidic cleaner with harsh effects.

To maintain the luster and shine of your natural stone, use a stone-safe polish about once a week. To polish stone, simply spray the polish directly onto the surface, then buff the surface until it’s dry with a lint-free cloth or dry paper towel.

Stone objects decay in all environments, but the modes of decay vary from one region to another. In the modern industrial countries acid deposition has accelerated the decay of stone. Many objects that survived centuries of weathering without serious damage have, in the present century, decomposed beyond recognition.
 

Topical sealers are coatings that will protect the surface area of the stone. This coating will guard against oil, water and other debris. They are cost-effective, easy to apply, and are slip resistant. However, low-quality coatings can discolor stone, and reapplying can often require harsh stripping.

Oil. Smooth stones may also be brought to a high, wet-look shine with oil. Jojoba oil is one good choice, as it will not become sticky or rancid as some kitchen oils will.
