Gum arabic slowly dissolves in cold water to form a thick, highly adhesive solution at a ratio of 1: 2. A thin layer of dissolved gum arabic dries to form a colorless, gloss, hard coating that can easily be dissolved again with water. It is very stable in dry conditions, does not yellow, cloud, or weather. However, it is very brittle, so plasticizers (glycerin, glucose, or granulated sugar) must be added. With a plasticizer added, it can be used to prepare solid watercolor paints that soften easily when moistened and can be diluted with water as needed.\u003cbr\u003eGum arabic solutions in water remain fluid even at high concentrations, a quality that sets them apart from all other water-soluble binders. This makes them suitable for watercolor and miniature painting: they produce rich shades of paint and allow even the smallest details to be rendered precisely.\u003c\/p\u003e\n\u003cp\u003ePreparing a gum arabic solution: Leave 100 parts Kordofan gum to swell in 200 parts cold water for one day, then dissolve it by heating. Add a small piece of camphor, borax, or a trace of formalin to prevent the solution from turning sour.\u003c\/p\u003e\n\u003cp\u003eGum arabic can also be emulsified with wax: Heat 5 parts powdered gum arabic, 4 parts beeswax, and 1 part dammar varnish to about 70 degrees Celsius, then add 10 parts hot boiled water with 2 parts glycerin.\u003c\/p\u003e\n\u003ch2\u003eProduct details:\u003c\/h2\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNatural Kordofan gum arabic\u003c\/li\u003e\n\u003cli\u003eSuitable for preparing an emulsion for tempera paints\u003c\/li\u003e\n\u003cli\u003eAs a binder for watercolor paints\u003c\/li\u003e\n\u003cli\u003eAs an emulsifying agent in some paints and emulsions\u003c\/li\u003e\n\u003cli\u003eAs a masking fluid for watercolor (to cover areas that need protection before applying watercolor paints)\u003c\/li\u003e\n\u003cli\u003eRemove it as soon as possible after applying the paints\u003c\/li\u003e\n\u003cli\u003ePack size: 100 ml\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cbr\u003e \u003cp\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Umton","offers":[{"title":"Default Title","offer_id":58668360008024,"sku":"UMT322810","price":4.95,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0861\/8010\/2488\/files\/umton-kordofan-gum-arabic-100-ml-ie-umt322810-1.jpg?v=1791240356","url":"https:\/\/artmie.fr\/products\/umton-kordofan-gum-arabic-100-ml-ie-umt322810","provider":"artmie.sk","version":"1.0","type":"link"}
