“You attending at it and aback think: oh my God we’ve got a allotment of Vietnam in here,” says Marcelo Carvalho, a administrator of Marble Granite Limestone Warehouse, as he explains the address of natural-stone kitchen worktops over man-made.
“Or Athens, or Italy, or Turkey, or India,” he continues, gesturing appear added than 400 stones from all over the apple ample in MGLW’s all-inclusive London warehouse.
Carvalho says granite acclimated to annual for about 70 per cent of MGLW’s sales for kitchen worktops, but in contempo years there’s been a about-face to quartz — a counterfeit bean — which today makes up the agnate percentage, as adjoin to granite’s beneath 10 per cent.
The actual 20 per cent is marble, which has remained “pretty constant”, alike admitting MGLW and added bean suppliers attention adjoin it for worktops, as the absorptive actual wears abominably with acerbic contact.
The growing address of counterfeit quartz is article that Carvalho puts bottomward to a array of factors, not atomic the internet. He mentions the “practicality” of quartz — it looks absolutely as specified, so is accessible to adjustment online. This is in adverse to the about-face in veining and colour of accustomed stone, alike in altered blocks mined from the aforementioned quarry.
As we clasp our way through perilous endless of bean slabs, with Carvalho pointing out his favourites, he says that they banal abounding added slabs of accustomed bean than man-made, admitting affairs far added of the latter, “because you charge to see it to buy it”.
Most of the accustomed bean in this barn acclimated to appear from Italy, Portugal and Spain, but over the accomplished 20 years quarries in Turkey and China accept abounding the market. According to the Observatory of Economic Complexity, 45 per cent of the world’s marble now comes from Turkey, with alone 18 per cent from Italy.
Supply and appeal can additionally be befuddled off antithesis by “the whim of fashion”, says Carvalho, citation the tenfold abatement in acceptance of crema marfil — a buttery Italian marble — a decade ago, and the adverse aftereffect on a accurate quarry.
One blazon of Italian marble that Carvalho sees as captivation its amount is Carrara. The Carrara quarries in the Apuan Alps accept been mined for added than 2,000 years: the Roman emperor Augustus boasted that he begin Rome a burghal of artery and larboard it a burghal of marble, and it was the bean admired by Michelangelo. The sculptor spent continued stretches of time at the quarries allotment stone.
Today, accouterment has acquired from oxen and chisels to diamond-edged saws and tractors. Blocks of marble extracted from these quarries are about three cubic metres in size, asperous cubes that are broken — “like a loaf of bread”, says Carvalho — and able at processing plants nearby.
The slabs are transported common either by address or by road, authoritative their way to wholesalers such as MGLW, who again advertise the slabs on to retailers and stonemasons.
At Capital Granite, a stonemason in Walthamstow, east London, the slabs are cut to appropriate ambit for installation. Actuality the tinny bellow of the radio is disconnected by the bark of huge advanced alien machinery.
A crane with assimilation pads moves the abundant bean on to apparatus benches; a diamond-bladed saw cuts the slab to size; a CNC apparatus cuts spaces for sinks or hobs; again there is the milling apparatus and a acid machine, with this aftermost action accomplished by hand.
One stoneworker is inputting abstracts into the automated saw. He checks the laser band by eye, again the automatic arm whirrs its architecture brand forth it, slicing calmly through the water-drenched stone. Water is consistently acclimated back acid bean to anticipate overheating, bedew bottomward the dust, accumulate a beeline band and anticipate chipping.
A acid gelled aroma anon fills the air, which the artisan tells me comes from the adhesive in this counterfeit stone, but he seems unfazed: “Here, it’s not a problem,” he says, pointing out the aerial beam and able extractor fan.
These assurance measures are vital, as alive with quartz has been anon affiliated to silicosis — an cureless ache acquired by inhaled silica particles triggering deepening and fibrosis in the lungs, as able-bodied as added lung diseases including tuberculosis, emphysema and cancer.
It’s a botheration that has risen forth with the acceptance of quartz, which can accept a silica agreeable as aerial as 90 per cent, as adjoin to granite, which is beneath than 45 per cent.
Hundreds of years ago, Italians acclimated to appear to the Torquay polishers to apprentice from them
Granite is not after its own ethical drawbacks, advancing beneath the spotlight in 2017 back adolescent bullwork and poor alive altitude were begin in abounding Indian quarries, area 45 per cent of the world’s granite is mined, according to the OEC.
In acknowledgment to this report, British retailers John Lewis and Habitat both took a ambit of their granite worktops off the market.
Carvalho says that there are some ecological allowances to application accustomed bean because there are beneath bogus chemicals in its composition. It is difficult, however, to avoid the carbon brand of alteration a 250kg slab of bean beyond the world.
A acquaintance band-aid for British kitchens comes by way of Britannicus Stone, founded in 2011. Administrator Orlando Boynes says: “Many of Britain’s stones acclimated to be advised adored afore the canicule of the Grand Tour, back the Italian marbles became the cachet symbols that they’ve remained.”
He is amorous about the “muted, admirable apple colours” of the British accustomed stones they supply, such as Devonian marble and the anemic Hopton Wood limestone, acclimated on the floors of Chatsworth.

Like abounding bean suppliers, Britannicus doesn’t clearly acclaim application its absorptive stones for kitchen worktops: “For a kitchen worktop that can absolutely be abused, we would beacon addition appear granite,” says Boyne, but he admits to bartering their marbles for high-end projects, back the attending of the kitchen is added important than circadian use.
The British “shining stones” can “really booty a polish”, says Boyne, black the abatement in our built-in abilities associated with this once-precious resource: “Hundreds of years ago, Italians acclimated to appear to the Torquay polishers to apprentice from them.”
When it comes to allotment a bean for a kitchen worktop, the artful is absolutely aloof the surface. Alongside applied and ethical considerations, the amazing faculty of accomplished and abode that lies anchored in age-old accustomed stones — whether in the marble of Carrara or of Devon — comes into comedy too.
