It is a lighter grade than our Shungite black and gives soft, dark grays that are fully lightfast and resistant to acids, alkalis and lime. Use it in oil, acrylic, egg tempera, watercolor and gouache.\u003c\/p\u003e\n\u003ch2\u003eKey facts\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e gray-black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePigment type:\u003c\/strong\u003e Natural mineral pigment (carbon-rich rock)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposition:\u003c\/strong\u003e non-crystalline carbon with silicate minerals, mainly quartz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Karelia, Russia (Lake Onega area)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpacity:\u003c\/strong\u003e opaque\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLightfastness:\u003c\/strong\u003e 8 of 8 on the Blue Wool Scale (supplier data)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemical resistance:\u003c\/strong\u003e alkali 5\/5, lime 5\/5, acid 5\/5 (supplier data, 5 = best)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable for:\u003c\/strong\u003e oil, acrylic, egg tempera, watercolor, gouache\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e 50 g jar · 1 kg bag\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHow to use\u003c\/h2\u003e\n\u003cp\u003eWork the powder into the binder with a palette knife or muller: linseed oil, acrylic medium, egg yolk for tempera or gum arabic for watercolor and gouache. Shungite is fairly hard (Mohs 3.5 to 4), so mull it thoroughly. It needs relatively little oil, about 25 g per 100 g (supplier data), and covers well, but oil paint made with it dries slowly. Use it for dark grays, underpainting and toned grounds.\u003c\/p\u003e\n\u003ch2\u003eAbout shungite\u003c\/h2\u003e\n\u003cp\u003eShungite takes its name from Shunga, a village on the north shore of Lake Onega in Karelia. The rock is about two billion years old: carbon from ancient organic sediments mixed with quartz and other silicates. Its carbon content varies widely, from a few percent to almost pure carbon (supplier data), which is why shungite pigments range from black to gray.\u003c\/p\u003e\n\u003ch2\u003eSafety\u003c\/h2\u003e\n\u003cp\u003eShungite rock contains quartz (crystalline silica): avoid breathing the dust. Handle dry pigment with care: avoid breathing the dust and contact with eyes. Wear a dust mask (FFP2\/N95) and gloves when working with the powder, work in a well-ventilated area and wipe up spills with a damp cloth. Do not eat, drink or smoke while working; wash your hands afterwards. Keep away from children and pets. For artistic and technical use only — not for cosmetics, food or tattoos.\u003c\/p\u003e\n\u003ch2\u003eFAQ\u003c\/h2\u003e\n\u003ch3\u003eHow is Shungite grey different from Shungite black?\u003c\/h3\u003e\n\u003cp\u003eBoth come from Karelian shungite rock. Shungite grey is a lighter gray-black grade; Shungite black is a deep black with a slightly bluish tone.\u003c\/p\u003e\n\u003ch3\u003eIs Shungite grey lightfast?\u003c\/h3\u003e\n\u003cp\u003eYes. The supplier rates it 8 of 8 on the Blue Wool Scale, and it resists acids, alkalis and lime (5 of 5).\u003c\/p\u003e\n\u003ch3\u003eDoes it have a Colour Index number?\u003c\/h3\u003e\n\u003cp\u003eWe do not give one: the PBk6 code sometimes quoted for shungite belongs to lamp black, a soot pigment.\u003c\/p\u003e","brand":"COLIBRI PIGMENTS LLC","offers":[{"title":"50g","offer_id":43252781875447,"sku":"","price":4.9,"currency_code":"USD","in_stock":true},{"title":"1kg","offer_id":43252781908215,"sku":"","price":85.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0643\/6696\/9079\/files\/shungite-grey_9d8e373f-b6de-4b63-adfc-6463d2d3ce91.jpg?v=1793366892","url":"https:\/\/colibripigments.com\/products\/shungite-grey","provider":"Colibri Pigments","version":"1.0","type":"link"}
