talc mineralTalc is a natural clay mineral known for being the world’s softest material and for its powdered form, known as talc powder or talcum powder. While it’s associated with other gemstones, talc isn’t often thought of as a gem.

Why is talc not considered to be a gemstone? It’s too soft to use in jewelry. However, certain talc-rich stones like soapstone are used for decor!

Additionally, talc is an important ingredient in numerous products, along with having significant industrial uses. 

Today, you’ll get the 411 on talc’s uses, history, healing properties, varieties, and prices!

About Talc Stone

Talc, sometimes called “kerite,” can form as crystals or massive stones, though crystals are rare. In its purest form, talc color is white to colorless with a pearly luster. However, inclusions like iron or aluminum oxide can create other colors like brown, gray, yellow, pink, and more.

When people say “talc,” they may be referring to one of four meanings:

  • Talc mineral

  • Talc’s rock varieties (which we’ll cover in a bit)

  • Industrial-grade talc powder

  • Cosmetic talc powder

Speaking of, what is talc used for?

Talc Uses

Talc ingredients span various industries. Names like talc, talcum powder, magnesium silicate, cosmetic talc, or talcum all refer to talc. Usually, talc is crushed up and dried into soft white talcum powder, which is used alone or incorporated into other ingredients. 

The array of applications comes from its unique properties:

  • Absorbent and friction-reducing: Keeps skin dry and rash-free; Prevents lumps from forming in ground-up or powdered ingredients

  • Greasy texture: Lubricates to make cosmetics smooth and silky

  • Thickening: Added to cakes, paints, and ceramics

  • Resistant to electricity and heat: Used in science lab counters, rubber, and electrical switchboards

On the mineral side of things, what are the characteristics of talc?

Talc Specifications & Characteristics

The talc chemical formula is Mg3Si4O10(OH)2, meaning it's a hydrated magnesium silicate. Common impurities are fluorine, iron, and aluminum.

Talc’s slippery texture comes from its structure: thin, stacked sheets that aren’t held together well, so they slip apart easily. 

In the original Mohs mineral hardness scale, talc hardness was the standard 1 ranking, meaning the least scratch-resistant. 

Factors like toughness and cleavage also play a role in durability. Unfortunately, talc cleavage is perfect (the weakest type), making it vulnerable to breakage, too. 

Here are all of talc’s mineral characteristics: 

  • Color: Usually green, white, or gray; Sometimes brown, yellow, pink, blue, black, or colorless

  • Crystal structure: Monoclinic or triclinic

  • Luster: Pearly, greasy, or dull

  • Transparency: Translucent (crystals) or opaque (masses)

  • Refractive index: 1.54-1.59

  • Density: 2.55-2.83

  • Cleavage: Perfect on [001]

  • Fracture: Uneven and flat, fibrous, or micaceous

  • Streak: White

  • Luminescence: Fluorescence sometimes present in soapstone variety; Pink, yellow, or green in SW-UV & light pink, greenish-yellow, or yellow in LW-UV

  • Pleochroism: Sometimes present in dark stones; Weak; Colorless to somewhat brown

Types of Talc

Talc doesn’t have the same kinds of varieties as many semi-precious gemstones. Depending on who you ask, talc either has one or two varieties: soapstone and steatite. 

Soapstone is a dense, magnesium-rich metamorphic rock largely composed of talc masses compacted together, along with other minerals. It has a foliated structure (thin sheet stacks). Some call it “soaprock” or “saponite.” 

However, miners and craft sellers often use “soapstone” as a general term for soapy, soft rocks often used in sculptures. In reality, many of the stones they’re referring to are serpentine or alabaster. 

Steatite: Soapstone Synonym or Variety?

Some use “steatite” as a synonym for soapstone, but others distinguish the two. 

The latter party considers steatite a soapstone variety that’s unfoliated and almost entirely talc.

Both soapstone and steatite (if you separate them) have a slightly higher hardness than talc, between 1 and 2.5. So… still pretty soft! 

Talc (Soapstone) Value Properties

Talc itself isn’t sold for jewelry or decor, but soapstone is! Below, we’ll highlight the factors that influence soapstone’s value.

Color

Soapstone’s color often varies by its source, but includes white, gray, green, brown, and red. It may have elements of white, blue, or green. Many are gray to grayish-green.

Cut

Soapstone is almost always carved or sculpted, with some rare cabochons

Artistic soapstone includes figurines and sculptures. Some architectural soapstone options are cookware, bar tops, and sinks.

Size

Soapstone rough is often huge, lending itself to multiple-pound carvings. Prices are higher for larger carvings. 

Treatments

When heated to 1,830–2,190 °F (1,000–1,200 °C), soapstone changes into two new stones: cristobalite and enstatite. Subsequently, the hardness increases to 5.5-6.5.

You know what it can become, but what does talc crystal do for you?

Talc Healing Properties

It may not be a gemstone, but talc is a healing stone

Colorless to white talc, like all white gemstones, can awaken higher spiritual awareness. Unsurprisingly, these crystals are perfect chakra stones for the center of spirituality: the crown chakra!

Green talc, along with other green gems, can provide nurturing, grounding, and stress-reducing benefits. 

Let’s look closer at the physical and emotional healing abilities.

Physical Healing

Talc crystals are said to help you establish a good sleep schedule, especially anxiety-induced insomnia. They can also help the kidney and liver function better.

Emotional Healing

Emotionally, talc is soothing and grounding. Crystal healers love it for bringing stillness and promoting mindfulness. Many recommend meditation with talc to reduce stress or bring better sleep. 

Just like crystal healing itself, talc goes back centuries!

Talc Meaning & History

The word “talc” derives from the Arabic talq and Persian tālk. Translations differ between “pure” or “mica,” for its similarity to mica minerals.

Ancient peoples called lots of minerals talc, including selenite. The Medieval Latin term talcum once referred to many different shiny minerals. 

Though evidence is scarce, Georgius Agricola is said to have officially named talc in 1546. However, as you may have guessed, talc goes way further back, particularly its soapstone variety.

Ancient Talc & Soapstone History

The first discovery of talc or soapstone is unclear but goes back millennia. 

Some of the earliest archeological evidence is a moose head soapstone carving from Finland called Elk’s Head of Huittinen dated to roughly 7,000 BC.

During the Stone Age, Scandinavians started using carving soapstone. They were the first to realize soapstone’s heat absorption and slow heat loss. This property was useful for metal-casting molds (along with cooking tools and fireplace insulators), which put Scandinavia into the Bronze Age around 1750 BC.

East-coast Native Americans likely discovered soapstone in the Appalachian Mountains. They carved assorted items that date back 3,000-5,000 years ago and include soapstone tobacco pipes, decor, and bowls. 

Even earlier evidence from about 8,000 years ago revealed west-coast Native Americans canoed 60 miles to San Clemente Island for soapstone. They carved soapstone bowls and human figurines. 

talc mineral history baby powder controversy

Modern Talc History & Controversy

If you ask “what is talc known for?” nowadays, you’ll likely hear negative connotations. Sadly, these associations are warranted in many cases.

In 1886, Robert Wood Johnson and his brothers started Johnson & Johnson™ (J&J). Soon after in 1894, J&J made the first talcum powder and marketed it as baby powder with the company slogan “Safety First.” 

But J&J learned their talc-based products weren’t safe decades ago. Researchers told them the products contained asbestos and posed an ovarian cancer risk. 

Instead of adding the recommended warning label, J&J started marketing another talcum powder product (Shower to Shower) and kept lawsuits under-wraps for years. 

A popular 2018 Reuters article presented evidence of asbestos-positive tests on J&J’s baby powder back to 1971 and proof the company knew about the asbestos. 

In the last few years, multimillion-dollar lawsuits against J&J from customers who suffered ovarian cancer or mesothelioma finally made an impact. In 2020, J&J officially took its talc-based baby powder off the US and Canadian markets. 

All that said, is mineral talc safe? If it doesn’t contain asbestos, it’s safe. Testing is required to know that, so always do your research and check the funding sources of organizations providing that information. 

Why is there asbestos in talc at all? It has to do with its formation.

Talc Formation & Sources

Talc and asbestos often form close together, so talc from deposits with asbestos often gets contaminated. These deposits commonly have other cancer-causing minerals like tremolite, too. However, not every talc deposit contains asbestos.

Formation-wise, what type of rock is talc found in? Miners classify talc deposits based on the rock it forms inside, with three current categories: 

  • Magnesium Carbonates: Silica-rich dolomite and magnesite; Accounts for over 50 percent of the world’s talc production

  • Serpentinites: Serpentine-rich metamorphic rocks, where talc replaces some of the serpentine minerals; Accounts for around 20 percent of talc

  • Alumino-Silicates: Rocks that produce clay minerals when weathered; Accounts for about 10 percent of talc

Talc forms through one of two ways: hydrothermal alteration or thermal metamorphism. Confused? Don’t worry, we’ll break each one down!

The hydrothermal alteration process starts with rocks low in silica but rich in magnesium. First, minerals like pyroxene or olivine become hydrated, changing into serpentine. Then, carbon dioxide transforms serpentine into magnesite and talc. 

The thermal metamorphism process is low-grade, meaning low to medium pressure and temperature transforms the rock, but not drastically.

Thermal metamorphism occurs in magnesium carbonate rocks like dolomite and magnesite. First, water carries the rock’s silica away, but the magnesium stays in place. The magnesium carbonates react with the silica water, creating newly talc-rich rocks.  

With that in mind, where is talc found?

Mining Locations

Currently, the world’s top talc producers, in order, are China, the USA, and Japan. In the USA, Montana, Texas, and Vermont lead talc production. 

Other major suppliers include:

  • Australia

  • Brazil

  • Canada

  • Central Africa

  • Finland

  • France

  • India

  • Russia

  • South Korea

Soapstone is less widespread. You’ll rarely find it in the Northern Hemisphere because seasonal freezing or glaciers destroy deposits. Brazil is the best soapstone source, as it lacks these conditions. 

Now, how much is talc schist worth? Or soapstone?

Talc Price & Value

Talc is incredibly affordable. Almost always sold as rough specimens, the prices range from $11-$16 by weight — about $16 for 1-2 lb pieces and $11 for 26-100 lb pieces.

Soapstone’s price is generally affordable, but more dependent on its quality, particularly historical value. For instance, an authentic, historical Inuit carving could fetch $4,000-$6,000 prices. 

Modern soapstone carving prices are much lower. Small figurines are often $4-$6 each, while medium-sized carvings (8-15 inches) are typically $20-$50. Rough soapstone is the least expensive, usually around $2 per pound. 

Talc Care and Maintenance

Talc is extremely delicate, and caring for crystals like this takes caution. You can easily scratch it, even with your fingernail. 

To clean talc, carefully rinse it in warm water. Distilled water is best, as mineral particles in tap water may scratch the stone. 

Keep talc in a vacuum-sealed or airtight container and store in a dry, cool area away from commonly frequented areas. 

Want A Stone Softer Than Silk?

No matter how many minerals you’ve held, none feel quite like talc. Its soft, slippery texture perfectly reflects its soothing, calming properties. Whether you use it for a soapstone countertop or a decorative carving to display on that counter, you can revel in its relaxing vibrations — and know you hold a slice of history!

O Talc Stone

Talk, koji se ponekad naziva "kerit", može se formirati u obliku kristala ili masivnog kamenja, iako su kristali rijetki. U svom najčišćem obliku, boja talka je bijela do bezbojna s bisernim sjajem. Međutim, inkluzije poput željeza ili aluminijevog oksida mogu stvoriti druge boje poput smeđe, sive, žute, ružičaste i još mnogo toga.

Kada ljudi kažu "talk", možda misle na jedno od četiri značenja:

  • Talk mineral

  • Talcove vrste stijena (koje ćemo malo pokriti)

  • Industrijski talk prah

  • Kozmetički talk u prahu

Kad smo kod toga, čemu služi talk?

Upotreba talka

Sastojci talka obuhvaćaju različite industrije. Nazivi poput talka, talka u prahu, magnezijevog silikata, kozmetičkog talka ili talka svi se odnose na talk. Obično se talk usitnjava i suši u meki bijeli talk, koji se koristi sam ili uklopljen u druge sastojke.

Niz aplikacija proizlazi iz njegovih jedinstvenih svojstava:

  • Upija i smanjuje trenje : Održava kožu suhom i bez osipa; Sprječava stvaranje grudica u mljevenim sastojcima ili sastojcima u prahu

  • Masna tekstura : Podmazuje kako bi kozmetika bila glatka i svilenkasta

  • Zgušnjavanje : dodaje se kolačima, bojama i keramici

  • Otporan na električnu energiju i toplinu : Koristi se u znanstvenim laboratorijskim brojačima, gumama i električnim razvodnim pločama

Što se tiče mineralne strane stvari, koje su karakteristike talka?

Tehnički podaci i karakteristike talka

Kemijska formula talka je Mg3Si4O10(OH)2, što znači da je hidratizirani magnezijev silikat. Uobičajene nečistoće su fluor, željezo i aluminij.

Skliska tekstura talka proizlazi iz njegove strukture: tankih, naslaganih listova koji se ne drže dobro zajedno, pa se lako rastavljaju.

U izvornoj Mohsovoj ljestvici tvrdoće minerala , tvrdoća talka bila je standardna ocjena 1, što znači najmanju otpornost na ogrebotine.

Čimbenici poput čvrstoće i cijepanja također igraju ulogu u trajnosti. Nažalost, talk je savršen (najslabiji tip), što ga čini ranjivim i na lomove.

Ovdje su sve mineralne karakteristike talka:

  • Boja : obično zelena, bijela ili siva; Ponekad smeđa, žuta, ružičasta, plava, crna ili bezbojna

  • Kristalna struktura : monoklinička ili triklinička

  • Sjaj : biserni, mastan ili bez sjaja

  • Transparentnost : prozirna (kristali) ili neprozirna (mase)

  • Indeks loma : 1,54-1,59

  • Gustoća : 2,55-2,83

  • Dekolte : savršeno na [001]

  • Prijelom : neravnomjeran i ravan, vlaknast ili liskunast

  • Niz : bijela

  • Luminescencija : Fluorescencija ponekad prisutna u sorti sapunice; Ružičasta, žuta ili zelena u SW-UV i svijetloružičasta, zelenkasto-žuta ili žuta u LW-UV

  • Pleokroizam : Ponekad prisutan u tamnom kamenju; Slab; Bezbojno do pomalo smeđe

soapstone talk mineral sorta

Vrste talka

Talk nema iste vrste varijanti kao mnoge poludrago drago kamenje . Ovisno o tome koga pitate, talk ima jednu ili dvije varijante: sapunicu i steatit.

Soapstone je gusta metamorfna stijena bogata magnezijem, uglavnom sastavljena od mase talka zbijenih zajedno s drugim mineralima. Ima lisnatu strukturu (tanke hrpe listova). Neki ga zovu "sapunski kamen" ili "saponit".

Međutim, rudari i prodavači obrta često koriste "sapunicu" kao opći izraz za sapunaste, meke stijene koje se često koriste u skulpturama. U stvarnosti, mnoga kamenja na koja govore je serpentina ili alabaster.

Steatit: Soapstone sinonim ili raznolikost?

Neki koriste "steatit" kao sinonim za kamen sapunice, ali drugi razlikuju to dvoje.

Potonja strana smatra steatit sortom kamena sapunice koja je nelista i gotovo u potpunosti talk.

I sapunica i steatit (ako ih odvojite) imaju nešto veću tvrdoću od talka, između 1 i 2,5. Dakle... još uvijek prilično mekana!

Svojstva vrijednosti talka (sapunice).

Talk se sam po sebi ne prodaje za nakit ili dekoraciju, ali kamen od sapunice jest! U nastavku ćemo istaknuti čimbenike koji utječu na vrijednost sapunice.

Boja

Boja kamena sapunice često varira ovisno o izvoru, ali uključuje bijelu, sivu, zelenu, smeđu i crvenu. Može imati elemente bijele, plave ili zelene boje. Mnogi su sive do sivkastozelene.

Izrezati

Sapun je gotovo uvijek izrezbaren ili isklesan, s rijetkim kabochonima .

Umjetnički kamen sapunice uključuje figurice i skulpture. Neke opcije arhitektonskog kamena od sapunice su posuđe za kuhanje, ploče za šankove i sudoperi.

Veličina

Grubi kamen od sapunice često je ogroman, pogodan za rezbarije od više kilograma. Cijene su veće za veće rezbarije.

Tretmani

Kada se zagrije na 1.830–2.190 °F (1.000–1.200 °C), kamen sapunice se mijenja u dva nova kamena: kristobalit i enstatit. Nakon toga, tvrdoća se povećava na 5,5-6,5.

Znate što to može postati, ali što za vas čini kristal od talka?

Ljekovita svojstva talka

Možda nije dragi kamen, ali talk je kamen koji liječi !

Bezbojni do bijeli talk, kao i svako bijelo drago kamenje , može probuditi višu duhovnu svijest. Ne iznenađuje da su ovi kristali savršeno kamenje čakre za centar duhovnosti: krunska čakra!

Zeleni talk, zajedno s drugim zelenim draguljima , može pružiti njegu, uzemljenje i smanjenje stresa.

Pogledajmo pobliže fizičke i emocionalne sposobnosti iscjeljivanja.

Fizičko iscjeljenje

Za kristale talka se kaže da vam pomažu uspostaviti dobar raspored spavanja, posebno nesanicu uzrokovanu anksioznošću. Također mogu pomoći boljem funkcioniranju bubrega i jetre.

Emocionalno iscjeljivanje

Emocionalno, talk umiruje i uzemljuje. Iscjelitelji kristalima ga vole jer donosi mir i promiče svjesnost. Mnogi preporučuju meditaciju s talkom za smanjenje stresa ili bolji san.

Baš kao i samo kristalno liječenje, talk seže stoljećima!

Značenje talka i povijest

Riječ “talc” potječe od arapskog talq i perzijskog tālk . Prijevodi se razlikuju između "čistog" ili "liskuna", zbog njegove sličnosti s mineralima liskuna.

Stari narodi su mnoge minerale nazivali talkom, uključujući selenit . Srednjovjekovni latinski izraz talk nekada se odnosio na mnoge različite sjajne minerale.

Iako su dokazi oskudni, kaže se da je Georgius Agricola službeno nazvao talk 1546. Međutim, kao što ste možda pretpostavili, talk seže daleko u prošlost, posebno njegova vrsta kamena sapunice.

sapunica talk mineral carving

Drevna povijest talka i sapunice

Prvo otkriće talka ili sapunice je nejasno, ali seže tisućljećima unatrag.

Neki od najranijih arheoloških dokaza je rezbarenje losove glave u kamenu od sapunice iz Finske pod nazivom Elkova glava Huittinena iz otprilike 7.000 godina prije Krista.

Tijekom kamenog doba, Skandinavci su počeli koristiti rezbarenje sapunice. Bili su prvi koji su shvatili apsorpciju topline kamena sapunice i spor gubitak topline. Ovo svojstvo bilo je korisno za kalupe za lijevanje metala (zajedno s alatima za kuhanje i izolatorima kamina), što je Skandinaviju stavilo u brončano doba oko 1750. pr.

Indijanci s istočne obale vjerojatno su otkrili kamen sapunice u gorju Appalachian. Izrezbarili su razne predmete koji datiraju prije 3.000-5.000 godina i uključuju lule za duhan od sapunice, dekor i zdjele.

Čak i raniji dokazi od prije otprilike 8000 godina otkrili su da su Indijanci sa zapadne obale vozili kanuima 60 milja do otoka San Clemente po kamen sapunice. Izrezbarili su zdjele od sapunice i ljudske figurice.

talk mineral history kontroverza dječjeg pudera

Moderna povijest talka i kontroverze

Ako pitate "po čemu je talk poznat?" danas ćete vjerojatno čuti negativne konotacije. Nažalost, ta su udruženja u mnogim slučajevima opravdana.

Godine 1886. Robert Wood Johnson i njegova braća osnovali su Johnson & Johnson™ (J&J). Ubrzo nakon toga, 1894., J&J je napravio prvi puder u prahu i plasirao ga kao dječji puder sa sloganom tvrtke “Safety First”.

Ali J&J je prije nekoliko desetljeća saznao da njihovi proizvodi na bazi talka nisu sigurni. Istraživači su im rekli da proizvodi sadrže azbest i predstavljaju rizik od raka jajnika.

Umjesto dodavanja preporučene oznake upozorenja, J&J je počeo plasirati još jedan proizvod s talkom (od tuša do tuša) i godinama skrivao tužbe.

Popularni članak Reutersa iz 2018. predstavio je dokaze o testovima pozitivnih na azbest na J&J-ovom dječjem puderu još od 1971. godine i dokaz da je tvrtka znala za azbest.

U posljednjih nekoliko godina, višemilijunske tužbe protiv J&J-a od strane mušterija koje su imale rak jajnika ili mezoteliom konačno su imale utjecaj. Godine 2020. J&J je službeno izbacio dječji puder na bazi talka s tržišta SAD-a i Kanade.

Sve što je rečeno, je li mineralni talk siguran? Ako ne sadrži azbest, sigurno je. Za to je potrebno testiranje, stoga uvijek istražite i provjerite izvore financiranja organizacija koje pružaju te informacije.

Zašto uopće ima azbesta u talku? To ima veze s njegovim formiranjem.

talk škriljasta stijena sa smaragdnim kristalima

Tvorba talka i izvori

Talk i azbest se često stvaraju blizu jedan drugom, pa se talk iz naslaga s azbestom često onečišćuje. Ove naslage obično sadrže i druge minerale koji uzrokuju rak, poput tremolita. Međutim, ne sadrži svaki depozit talka azbest.

Što se tiče formacije, u kojoj se vrsti stijene nalazi talk? Rudari klasificiraju naslage talka na temelju stijene koju stvara unutar, u tri trenutne kategorije:

  • Magnezij karbonati : dolomit i magnezit bogat silicijevim dioksidom; Na njega otpada preko 50 posto svjetske proizvodnje talka

  • Serpentiniti : metamorfne stijene bogate serpentinom, gdje talk zamjenjuje neke od minerala serpentina; Čini oko 20 posto talka

  • Alumino-silikati : Stijene koje proizvode glinene minerale kada su istrošene; Čini oko 10 posto talka

Talk nastaje na jedan od dva načina: hidrotermalna promjena ili termalni metamorfizam. Zbunjen? Ne brinite, svaku ćemo razbiti!

Proces hidrotermalne izmjene započinje kamenjem s malo silicija, ali bogatim magnezijem. Prvo, minerali poput piroksena ili olivina postaju hidratizirani, pretvarajući se u serpentin. Zatim, ugljični dioksid pretvara serpentin u magnezit i talk.

Proces toplinskog metamorfizma je niskog stupnja, što znači da niski do srednji tlak i temperatura transformiraju stijenu, ali ne drastično.

Toplinski metamorfizam javlja se u stijenama magnezijevog karbonata kao što su dolomit i magnezit. Prvo, voda nosi silicij iz stijene, ali magnezij ostaje na mjestu. Magnezijevi karbonati reagiraju sa silicijevom vodom, stvarajući nove stijene bogate talkom.

Imajući to na umu, gdje se nalazi talk?

Lokacije rudarstva

Trenutno su vodeći svjetski proizvođači talka, po redu, Kina, SAD i Japan. U SAD-u Montana, Texas i Vermont vode proizvodnju talka.

Ostali glavni dobavljači uključuju:

  • Australija

  • Brazil

  • Kanada

  • središnja Afrika

  • Finska

  • Francuska

  • Indija

  • Rusija

  • Južna Korea

Sapunica je manje rasprostranjena. Rijetko ćete ga naći na sjevernoj hemisferi jer sezonsko smrzavanje ili ledenjaci uništavaju naslage. Brazil je najbolji izvor kamena sapuna jer mu nedostaju ovi uvjeti.

Sada, koliko vrijedi škriljac od talka? Ili kamen od sapunice?

Cijena i vrijednost talka

Talk je nevjerojatno pristupačan. Gotovo uvijek se prodaju kao grubi primjerci, cijene se kreću od 11 do 16 dolara po težini - oko 16 dolara za komade od 1-2 lb i 11 dolara za komade od 26-100 lb.

Cijena Soapstonea općenito je pristupačna, ali više ovisi o njegovoj kvaliteti, posebice povijesnoj vrijednosti. Na primjer, autentična, povijesna inuitska rezbarija mogla bi po cijeni od 4000 do 6000 dolara.

Moderne cijene rezbarenja kamena od sapunice su mnogo niže. Male figurice često koštaju 4-6 dolara po komadu, dok rezbarije srednje veličine (8-15 inča) obično koštaju 20-50 dolara. Grubi kamen za sapun je najjeftiniji, obično oko 2 dolara po funti.

Njega i održavanje talka

Talk je iznimno nježan, a briga za ovakve kristale zahtijeva oprez. Lako ga možete ogrebati, čak i noktom.

Za čišćenje talka pažljivo ga isperite u toploj vodi. Destilirana voda je najbolja, jer mineralne čestice u vodi iz slavine mogu izgrebati kamen.

Čuvajte talk u vakuumsko zatvorenoj ili hermetički zatvorenoj posudi i čuvajte na suhom, hladnom mjestu dalje od mjesta koja često posjećuju.

Želite kamen mekši od svile?

Bez obzira na to koliko minerala ste držali, nijedan se ne osjeća kao talk. Njegova meka, skliska tekstura savršeno odražava njegova umirujuća, umirujuća svojstva. Bilo da ga koristite za radnu ploču od kamena od sapunice ili ukrasnu rezbariju za izlaganje na tom pultu, možete uživati u njegovim opuštajućim vibracijama - i znati da imate djelić povijesti!
