(This article is specifically designed for Indian subcontinent)Marble StoneMarble stone should be hard, sound, dense, and homogeneous in texture with crystalline texture. It should generally be uniform in color, veining and be free from stains, cracks, decay and weathering etc.
Precautions while Purchasing Marble Stone1. Check the quality of marble stoneand compare the available quality in your area with the quality of stone available in any other reputed marketnear yourarea..2. Try rates from three or four shops. The rates may vary in following two ways.According to quality of the stone According to size of stone slab as the smaller the size of stone slabs is, the cheaper the rate of stone slab would be. 3.Make sure thatthe stone being offered is hard. This can be verified by pressing the stone with some hard object forcibly. In case of katcha stone the chips of stone will split from stone slab.4. Make sure that the stone slab gives clear ringing sound when struck. 5. Verify that the stone is free from any stain i.e. deep cut or mark on the surface. 6. Confirm that the stone has uniform color without any spot. 7. Check the thickness of stone pieces and take supply of only those pieces that have the same thickness. 8. Check stone pieces thoroughly because it is generally observed that the shopkeeper place superior pieces on the top of stack and inferior pieces below. 9. Measure the stone by smallest rectangle at the time of payment. The broken piece should not be measured.
10. Make sure that the loading is done in your presence as the labor at the shopmay alsoload inferior or rejected pieces instead of superior pieces of the same size in the vehicle. 11. Get the pieces of stone laid vertically; not horizontally in the vehicle. If loading is done in horizontally , the stone slab may break during transport.
Precautions While Purchasing Granite StoneGranite is a stonethat isgaining popularity because of its hardness, ability to take good polish and wide variety of colors available in it. The following precautions should be taken while purchasing granite stone.
1) Check patches on surface of discoloration, hairlines, cracks, deep pin holes on the surface. These signify a weak slab and will cause problem.2) Check artificial coloringas itis a huge problem with stones now a daysespeciallythe black granite. Stone merchants rub industrial oil on the surface to intensify the color and creates a deep black and rich polishthat wears off in matter of weeks. 3) Verify artificial color by rubbing with cloth dipped in kerosene oil or white petrol. If cloth brings black color then it is a fake color. 4) Also check the back of the slab for circular mark. These are made by kerosene cutter which is used to cut the block of granite slab. This shows that the cutting process is wrong. The granite slab should be water cut having no circular mark on the back of the slab.
Granite counters are highly scratch resistant and will not show wear from daily use. Granite countertops requires a lot of maintenance. Heat will cause granite countertops to chip and crack. Granite counters are heat resistant and can withstand the heat of hot pots and pans without damage.
Extremely old granite countertops that have had their surfaces worn away by constant handling and use can weaken and crack over time. Likewise, heavy objects, such as cast iron pots dropped with enough force on the stone, can cause granite to crack. Granite is at its weakest during transportation.
Granite is high maintenance. Granite is stain, scratch, heat and chemical resistant. Some granites dont require any sealing at all. On a daily basis, dusting, wiping up spills and using potholders or trivets are the extent of maintenance and these are common to most countertop materials.
How Long Do Granite Countertops Last? Granite countertops last longer than most other materials, offering a durable and beautiful material to use throughout your kitchen. Granite can last for 100+ years; after all it is a natural substance found deep in the earth that is already millions of years old.
You can simply clean up spills or do general cleaning using a wet cloth and dish soap like Ivory or Dawn. Never use an abrasive pad on any natural stone; if necessary soak sticky or dry food stains with water or a PH neutral cleanser first, then wipe away with a soft cloth.
To put a shine on your granite put a little cooking oil on a soft cleaning cloth and wipe it across the countertop. Buff it gently. This makes the counter a little bit stain-resistant and gives it a glossy shine. Even if you know how to clean countertops correctly your granite will need to be resealed periodically.
Cracks, fissures, and breaks in your granite can all be repaired using epoxy. If your granite breaks, you may be able to repair it by using epoxy resin to bind the two pieces together, then fill any remaining cracks using more resin.
Installers can do minor repairs, but granite crack repair is a major repair (with a separated crack). Cracks in granite are repaired first by filling with an acrylic or using a color-matched epoxy to glue the pieces back together.
Resurfacing granite, including polishing and sealing, ranges from $200 to $1,200, depending on the damage and work needed. You may opt to repair small chips and cracks yourself using a DIY granite epoxy resin repair kit for $35 to $100.
The minerals in hard water can leave streaks or build-up on the slick stone surface, which means the granite looks cloudy. Add 1 tablespoon of liquid dish soap to 1 gallon of warm water and mix until suds form. This can be used daily without harming the granite countertop.
Windex contains ingredients that can permanently damage the granite. While the most common damage done by Windex is dulling the shine of the countertops, it can also cause pitting. Windex can strip the sealer off of your granite countertops, leaving the granite susceptible to staining and other damage.
When granite and other types of natural stone are properly sealed, they repel liquids and prevent them from permeating into the stone. Without sealing, water will penetrate the stone and leave behind water marks, some small, some large, giving your stone a perpetually dirty appearance.
The price of resealing costs $0.50-$2 per square foot. Professional restorers finish the project by adding a sealer to the floor or counter. The sealant helps prevent future stains and protects the shine.

Rocks are infamously durable and can be an eyesore in a garden, in a landscaping project or it may just be in the way. The problem usually is that the rock is too heavily embedded or it's simply too heavy to lift or roll out of the way. By breaking a rock you can decrease the load and remove it in a safer manner.
If you need to move big rocks, breaking them up is a good way to decrease the load and make them safer to move. The easiest way to break big rocks is by using a sledgehammer. Just hit a specific point on the rock over and over with the sledgehammer until it cracks. If you dont have a sledgehammer you can also use a regular hammer to break up rocks. If the rock is small enough, place a canvas bag or pillowcase around it to protect yourself from flying debris. Then, hit the rock with the hammer, gently at first, gradually hitting it harder until it cracks. To learn how to split an embedded boulder, read on! Did this summary help you?YesNo
We have often noticed that procurement and quality control departments are puzzled when it comes to gauging the quality of natural stone slabs (marble, granite, limestone, sandstone or slate). To fill this gap, we have formulated an overview of simple to use techniques that anyone can use to easily check the quality of granite/marble. We will lay out very simple steps that anyone can follow. But before that, there are some basics:
First and the foremost aspect of buying stone is realizing that names of these stones dont really matter much unless youre looking for very popular industry-standard stones like black/grey granite etc. Best way to go is to actually see the stone slabs in person. However, this is not always practical. Samples are a great alternative, but one must know:
We have seen so many projects that use white granite for their staircases. Despite our consultation, architects are adamant about using white granite which is fine but they always forget to seal it! White granite is very porous and prone to chemical attacks. Therefore, we advise our clients to use white porcite for their applications.
In India, the customary thickness of granite slabs is 18mm, for marble, it is 20mm and differs for sandstone, limestone etc. Apart from just the thickness of the stone, there must be consistency across the thicknesses of slabs. Slabs of varying thicknesses are very difficult to work with, especially for flooring.
Quality control departments really need to revamp their strategy when it comes to gauging the quality of marble/granite. Here are some tips, that we, as a natural stone company, use to quality check our goods after they have been manufactured.
This is one of the most overlooked factors for gauging the quality of the stone. The quality of polish of the stone plays a very imperative role in the overall finish of the project. Using dull marble/granite in your projects may unknowingly take away from a pristine finish. At Petrosstone we use special surface roughness meters that gauge the quality of the surface finish for all our products. Roughness meters are expensive and not very practical in most cases.
Consistency in thicknesses across granite/marble slabs is essential, especially for applications such as floorings. Checks like these are best performed when the slabs are unloaded from the trucks. This way, it is easier to sort out the non-conforming slabs onto the different stand. A tolerance of 0.1-0.3mm is acceptable, but anything over that may be a concern depending on the application of the stone.
Firm slabs with no cracks/holes add the overall strength to the slab. If these will be cut into thin sizes for door and window frames, this is even more crucial. Partially damaged slabs do not hold well under stress and might break while handling.
Companies must ask their suppliers to submit at least 2 samples during the selection process. One sample must, at all times, be with the quality department and the other with the procurement. When the goods are delivered, each block must be checked against these samples. We are confident that quality control departments will start noticing an enormous difference between the samples submitted and the final slabs delivered. This is because suppliers usually submit samples of fresh quality slabs (premium quality slabs) but deliver sub-par goods at the site. At petrosstone we believe in legitimate business practices and hence, refrain from any such activities that jeopardize our customer relationships. In fact, these articles on QA have been a solemn attempt to safeguard our readers from falling into such traps.
Ordering your slabs to be custom sized can save a lot of time and energy spent Unlike most companies, we can provide custom-sized slabs. We can provide custom-sized slabs that best fit the required application(after being cut to size). This way, companies dramatically reduce their material wastage to the extent that it brings down the price of stone to the price of vitrified tiles!
Bends are more common in softer stones like marble. Bent slabs are complicated to work with. The most effective way to prevent bends is to use slabs thicker than 20mm. This practically gets rid of any bends.
Artificial colouring can make the stone disguise its defects like cracks, lines, patches. Sometimes, even completely change its appearance. Use a tool (5-6 on the Mohrs Hardness scale) to scratch the surface of the stone. If it does not leave a scratch, this means that the stone has an artificial colour coating. These coatings differ from sealants, which we at petrosstone use to shield against chemical attacks.
If you are using granite/marble tiles for your project, it is important to check for even sizing and right-angled cuts. This will save a lot of time and energy during the fitting process. Uneven sizes with incorrect angled cuts are very difficult to deal with.
