It needs little oil (18–20 g per 100 g of pigment, supplier data) and covers well, but its tinting strength is modest, so it is best used on its own or in light turquoise tints rather than as a strong mixing color. It is lime- and alkali-proof, suits fresco, and withstands about 1250 °C (supplier data), so it can also color ceramics.\u003c\/p\u003e\n\u003ch2\u003eAbout cobalt titanate\u003c\/h2\u003e\n\u003cp\u003eCobalt titanate is one of the titanium-based mixed metal oxide pigments discovered around 1930. It is made by calcining cobalt and titanium compounds at high temperature. Its Colour Index name, Pigment Green 50, covers shades from green to blue-green; bluer grades like this one are sold by paint makers as cobalt teal or cobalt turquoise light.\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\u003eWhy is a blue pigment listed as PG50 (Pigment Green 50)?\u003c\/h3\u003e\n\u003cp\u003eCobalt titanate ranges from green to blue-green, and the Colour Index files it as a green. Light blue-green grades like ours are sold by paint makers as cobalt teal or cobalt turquoise light.\u003c\/p\u003e\n\u003ch3\u003eCan it be used in fresco and ceramics?\u003c\/h3\u003e\n\u003cp\u003eYes. Our supplier rates it 5 of 5 for alkali and lime resistance, lists it for fresco and ceramics, and gives heat resistance up to 1250 °C.\u003c\/p\u003e","brand":"COLIBRI PIGMENTS LLC","offers":[{"title":"50g","offer_id":51694585053431,"sku":null,"price":15.9,"currency_code":"USD","in_stock":true},{"title":"1kg","offer_id":51696500310263,"sku":null,"price":280.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0643\/6696\/9079\/files\/cobalt-titanate-blue.jpg?v=1793370302","url":"https:\/\/colibripigments.com\/products\/cobalt-titanate-blue","provider":"Colibri Pigments","version":"1.0","type":"link"}
