Its hue ranges from fiery scarlet to deep orange, with a crystalline brilliance that sets it apart from earth reds and iron oxides. When finely ground, it yields an opaque pigment with strong covering power and glowing warmth.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eCompared to vermilion or cinnabar, Realgar leans more orange and is somewhat softer in body, making it highly striking but chemically unstable when exposed to light over time.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eHistory\u003c\/p\u003e\u003cp\u003eRealgar has been known and used since antiquity in Egypt, Mesopotamia, China, and later throughout Europe. It was employed in manuscripts, wall paintings, and ritual objects as a source of luminous red-orange. In alchemy, it was associated with transformation and was considered one of the arsenical sulfides alongside orpiment.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eChinese painters used it for brilliant red passages in scrolls and decorations, while in Europe it appeared in medieval manuscripts and early Renaissance painting. However, its light sensitivity caused it to darken over time, sometimes turning into yellow pararealgar (As‚ÇÇS‚ÇÉ).\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eBy the 18th century, Realgar had largely fallen out of use as safer, more stable reds (vermilion, later cadmium reds) became available. Today, it remains a pigment of historical and conservation interest rather than a common artist\u003cspan\u003e'\u003c\/span\u003es material.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003ePrecautions: \u003c\/p\u003e\u003cp\u003eKeep out of reach of children and pets. \u003c\/p\u003e\u003cp\u003eDo not consume. \u003c\/p\u003e\u003cp\u003eNot for cosmetic or food usage. \u003c\/p\u003e\u003cp\u003eDo not spray apply. \u003c\/p\u003e\u003cp\u003eFor further health information contact a poison control center. \u003c\/p\u003e\u003cp\u003eUse care when handling dry pigments and avoid dust formation. \u003c\/p\u003e\u003cp\u003eUse particular caution with fibrous, fine, or toxic pigments. \u003c\/p\u003e\u003cp\u003eDo not eat, drink, or smoke near dry pigments. \u003c\/p\u003e\u003cp\u003eAvoid breathing in pigment dust and use a NIOSH-certified dust respirator with sufficient rating for dry pigment. \u003c\/p\u003e\u003cp\u003eWash hands immediately after use or handling. \u003c\/p\u003e\u003cp\u003eIf dust is likely, always wear protective clothing to keep out of eyes, lungs, off skin, and out of any contact as well as keep area ventilated. \u003c\/p\u003e\u003cp\u003eWarnings and bottle information are abbreviated.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003ePigment Information\u003c\/p\u003e\u003cp\u003ePigment Type: Natural Mineral\u003c\/p\u003e\u003cp\u003eChemical Composition: As₄S₄ (Arsenic Sulfide, Tetraarsenic Tetrasulfide)\u003c\/p\u003e\u003cp\u003eSuitable Mediums: Watercolor, Oil, Tempera, Acrylic, Encaustic, Cold Wax, Casein, Milk, Swedish Flour, Lime \/ Fresco\u003c\/p\u003e\u003cp\u003eLightfastness: Poor (light-sensitive; degrades to pararealgar)\u003c\/p\u003e\u003cp\u003eOpacity: Opaque\u003c\/p\u003e\u003cp\u003eOther Names: Ruby Sulfur, Ruby of Arsenic, Sandarac, Red Arsenic\u003c\/p\u003e\u003cp\u003eColor Index Code: Natural Inorganic\u003c\/p\u003e","brand":"Morrow Archival","offers":[{"title":"2 Grams","offer_id":47875246948574,"sku":"PM-209-0000-0002g","price":20.0,"currency_code":"USD","in_stock":true},{"title":"10 Grams","offer_id":47875246981342,"sku":"PM-209-0000-0010g","price":40.0,"currency_code":"USD","in_stock":true},{"title":"20 Grams","offer_id":47875247014110,"sku":"PM-209-0000-0020g","price":60.0,"currency_code":"USD","in_stock":true},{"title":"50 Grams","offer_id":47875247046878,"sku":"PM-209-0000-0050g","price":110.0,"currency_code":"USD","in_stock":true},{"title":"100 Grams","offer_id":47875247079646,"sku":"PM-209-0000-0100g","price":180.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0739\/2821\/2702\/files\/77062337-dd10-4d28-b90f-b461777c1324-copy.jpg?v=1769982486","url":"https:\/\/morrowarchival.com\/products\/realgar-pigment-genuine-425137874","provider":"Morrow Archival","version":"1.0","type":"link"}
