In pre-dynastic ancient Egypt, it was used for eye-make-up and in ancient panel and wall painting. Up until the 18th century, malachite remained the most important green used in painting, though in Europe it was not as extensively used as azurite. Its properties are similar to those of the blue basic copper carbonate, although malachite contains a greater amount of combined water. It turns yellowish green in oil, is permanent in fresco when mixed up fresh with lime, and is also suitable for tempera.\u003c\/p\u003e\n\u003cp\u003eIn ancient times, the Sinai Peninsula and Eastern Egypt were famous sources for malachite. The raw malachite from Kremer Pigmente comes from Eastern Congo. Since it is a very crude ore, it then goes through a careful process of separation by hand, crushing, grinding, sieving, and levigation, inspired by old European and Chinese recipes, in order to “clean” its surface.\u003c\/p\u003e\n\u003cp\u003eThis rich green copper mineral is known for its bold streaks - ground and sieved.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cul class=\"articleProperties\"\u003e\n\u003cli\u003e\n\u003cspan class=\"articlePropertyName\"\u003eChemical description:\u003c\/span\u003e \u003cspan class=\"articlePropertyValue\"\u003eCopper hydroxide carbonate, Cu2(CO3)(OH)2\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"articlePropertyName\"\u003eChemical Formula:\u003c\/span\u003e \u003cspan class=\"articlePropertyValue\"\u003eCu2(CO3)(OH)2\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"articlePropertyName\"\u003eLightfastness - thinned:\u003c\/span\u003e \u003cspan class=\"articlePropertyValue\"\u003e8 (1 is bad, 8 is best)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"articlePropertyName\"\u003eLightfastness - medium:\u003c\/span\u003e \u003cspan class=\"articlePropertyValue\"\u003e8 (1 is bad, 8 is best)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"articlePropertyName\"\u003eLightfastness - concentrated:\u003c\/span\u003e \u003cspan class=\"articlePropertyValue\"\u003e8 (1 is bad, 8 is best)\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"articlePropertyName\"\u003eColourIndex:\u003c\/span\u003e \u003cspan class=\"articlePropertyValue\"\u003ePB 30.77420\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"articlePropertyName\"\u003eSuitability:\u003c\/span\u003e \u003cspan class=\"articlePropertyValue\"\u003eAcrylics, Tempera, Watercolour \/ Gouache\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"articlePropertyName\"\u003eColours:\u003c\/span\u003e \u003cspan class=\"articlePropertyValue\"\u003eGreen\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"articlePropertyName\"\u003eForms:\u003c\/span\u003e \u003cspan class=\"articlePropertyValue\"\u003epowder\u003c\/span\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan class=\"articlePropertyName\"\u003eSolubility in water:\u003c\/span\u003e \u003cspan class=\"articlePropertyValue\"\u003einsoluble\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Kremer","offers":[{"title":"Default Title","offer_id":63643661205834,"sku":"K103001","price":10.1,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1056\/0759\/4314\/files\/malachite_natural.jpg?v=1792484223","url":"https:\/\/www.atlantisart.co.uk\/products\/kremer-pigments-malachite-natural-10g","provider":"Atlantis Art Materials","version":"1.0","type":"link"}
