Its tinting strength is moderate, and with white it gives clean turquoise tints. It keeps its color in lime and is listed for fresco and silicate binders; our supplier gives heat resistance up to 1000 °C. Store it dry in a closed jar.\u003c\/p\u003e\n\u003ch2\u003eAbout Cobalt Chrome Sea Wave\u003c\/h2\u003e\n\u003cp\u003eCobalt chromite blue-green is a modern mixed metal oxide pigment, made by calcining cobalt(II), chromium(III) and aluminum oxides above 1350 °C into a spinel crystal; zinc, magnesium, silicon, titanium or zirconium oxides may be added to adjust the shade. Paint makers sometimes sell PB36 as cerulean blue or cobalt turquoise, but genuine cerulean is cobalt stannate, PB35.\u003c\/p\u003e\n\u003ch2\u003eSafety\u003c\/h2\u003e\n\u003cp\u003eContains cobalt compounds: may cause allergic skin or respiratory reactions; harmful if inhaled. 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\u003eIs Cobalt Chrome Sea Wave the same as cerulean blue?\u003c\/h3\u003e\n\u003cp\u003eNo. It is cobalt chromite (PB36), a greener turquoise. Genuine cerulean is cobalt stannate (PB35), which we sell as Cerulean blue.\u003c\/p\u003e\n\u003ch3\u003eDoes it contain toxic chromate?\u003c\/h3\u003e\n\u003cp\u003eNo. Its chromium is trivalent, locked in the spinel crystal; it is not a hexavalent chromate. It does contain cobalt, so avoid inhaling the dust.\u003c\/p\u003e\n\u003ch3\u003eIs it lightfast?\u003c\/h3\u003e\n\u003cp\u003eYes. Our supplier rates it 8 of 8, and reference sources give PB36 the top ASTM lightfastness rating, I.\u003c\/p\u003e","brand":"COLIBRI PIGMENTS LLC","offers":[{"title":"25g","offer_id":49301718401271,"sku":null,"price":18.9,"currency_code":"USD","in_stock":true},{"title":"1kg","offer_id":49301718434039,"sku":null,"price":660.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0643\/6696\/9079\/files\/cobalt-chrome-sea-wave_7b469112-c218-49b2-b41b-b6009d2f2954.jpg?v=1793366822","url":"https:\/\/colibripigments.com\/products\/cobalt-chrome-sea-wave","provider":"Colibri Pigments","version":"1.0","type":"link"}
