This pigment is derived from reacting cobalt oxide with aluminum oxide, creating an exceptionally durable and brilliant blue. Unlike other blues such as Ultramarine, Cobalt Blue is known for its clear, bright, luminous quality, excellent opacity, and smooth handling properties.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eCobalt Blue has exceptional lightfastness, making it highly durable for both classical and contemporary artwork. It blends seamlessly with other pigments, offering rich, natural blues in painting. Its semi-opaque quality allows for excellent layering, depth, and shading in oil, watercolor, and tempera applications. Compared to other blues such as Phthalo Blue or Prussian Blue, it provides a more clear chroma, making it ideal for landscapes, skies, portraits, and abstract works.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eHistory\u003c\/p\u003e\u003cp\u003eBlue pigments have been highly valued for thousands of years, with early civilizations using lapis lazuli and azurite to create blue hues for art and decoration.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eDuring antiquity, natural blue pigments were costly and rare, with Egyptian Blue and ground lapis lazuli being the primary sources. These natural blues were difficult to obtain and limited to high-status artworks and royal commissions. Small amounts of cobalt were used in Egypt in ground glass called smalt. \u003c\/p\u003e\u003cbr\u003e\u003cp\u003eIn 1802, Cobalt Blue was first synthesized by the French chemist Louis Jacques Th√©nard. He discovered that firing cobalt salts with alumina produced a stable, brilliant blue. This innovation provided artists with a permanent and affordable alternative to natural lapis lazuli.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eBy the 19th and early 20th centuries, Cobalt Blue became widely used in fine art and ceramic applications. Artists such as J.M.W. Turner, Claude Monet, and Pierre-Auguste Renoir used Cobalt Blue for skies, water, and atmospheric effects, appreciating its soft yet intense chroma. In the pictured artwork 'Music in the Tuileries Gardens' by Edouard Manet, the bright blue of the women's opulent scarves in the front are rich cobalt blue mixed with white.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eToday, Cobalt Blue remains a standard pigment in professional artist palettes due to its historical significance, stability, and unique color properties. It is widely used in oil, acrylic, and watercolor painting, as well as ceramics and glassmaking.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003ePigment Information\u003c\/p\u003e\u003cp\u003ePigment Type: Synthetic (Cobalt Aluminate) from minerals (CoAl₂O₄)  \u003c\/p\u003e\u003cp\u003eSuitable Mediums: Watercolor, Oil, Tempera, Acrylic, Encaustic, Cold Wax, Casein, Milk, Swedish Flour, Lime \/ Fresco, Ceramics\u003c\/p\u003e\u003cp\u003eLightfastness: Best \u003c\/p\u003e\u003cp\u003eOpacity: Semi-opaque \u003c\/p\u003e\u003cp\u003eOther Names: Thenard\u003cspan\u003e'\u003c\/span\u003es Blue, Cobaltous Aluminate, Mineral Blue \u003c\/p\u003e\u003cp\u003eColor Index Code: PB28\u003c\/p\u003e\u003cp\u003eImage: 'Music in the Tuileries Gardens' by Edouard Manet from the National Gallery\u003c\/p\u003e","brand":"Morrow Archival","offers":[{"title":"2 Grams","offer_id":47875250716894,"sku":"PS-608-0000-0002g","price":6.0,"currency_code":"USD","in_stock":true},{"title":"10 Grams","offer_id":47875250749662,"sku":"PS-608-0000-0010g","price":12.0,"currency_code":"USD","in_stock":true},{"title":"20 Grams","offer_id":47875250782430,"sku":"PS-608-0000-0020g","price":22.0,"currency_code":"USD","in_stock":true},{"title":"50 Grams","offer_id":47875250815198,"sku":"PS-608-0000-0050g","price":40.0,"currency_code":"USD","in_stock":true},{"title":"100 Grams","offer_id":47875250847966,"sku":"PS-608-0000-0100g","price":85.0,"currency_code":"USD","in_stock":true},{"title":"500 Grams","offer_id":47875250880734,"sku":"PS-608-0000-0500g","price":250.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0739\/2821\/2702\/files\/74f9e82c-58c8-4e50-8f88-7a6236c283f6-copy.jpg?v=1769982698","url":"https:\/\/morrowarchival.com\/products\/cobalt-blue-pigment-425137691","provider":"Morrow Archival","version":"1.0","type":"link"}
