It gives a pale, creamy, opaque yellow for oil and egg tempera, and like other lead compounds it speeds up the drying of oil.\u003c\/p\u003e\n\u003ch2\u003eKey facts\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e pale, creamy yellow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePigment type:\u003c\/strong\u003e Synthetic inorganic pigment (lead oxide)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour Index:\u003c\/strong\u003e PY46 (C.I. 77577)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComposition:\u003c\/strong\u003e lead(II) oxide, PbO (yellow orthorhombic form)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e synthetic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlso known as:\u003c\/strong\u003e lead monoxide, Flemish yellow\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpacity:\u003c\/strong\u003e opaque\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLightfastness:\u003c\/strong\u003e 7 of 8 on the Blue Wool Scale (supplier data)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChemical resistance:\u003c\/strong\u003e dissolves in acids and in strong alkalis; grays or darkens in sulfur fumes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSuitable for:\u003c\/strong\u003e oil, acrylic, egg tempera, watercolor, gouache\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNot recommended for:\u003c\/strong\u003e fresco (lead pigments tend to blacken in wall paintings)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackaging:\u003c\/strong\u003e 50 g jar · 1 kg bag\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHow to use\u003c\/h2\u003e\n\u003cp\u003eWet the powder with a little binder before mulling to keep dust down, then mull it into linseed oil, egg yolk, gum arabic or acrylic medium with a glass muller. In oil it acts as a drier, so the paint sets faster than usual. Keep it apart from sulfide pigments such as orpiment, realgar and cinnabar, since sulfur darkens lead colors, and protect finished work with a binder film or varnish.\u003c\/p\u003e\n\u003ch2\u003eAbout massicot\u003c\/h2\u003e\n\u003cp\u003eYellow lead monoxide is one of the oldest manufactured yellows and has been found at predynastic sites in Egypt. It forms when lead or lead white is heated in air, and by controlled heating and cooling it can be switched between yellow massicot and red litharge. Old texts also used the name massicot for lead-tin yellow, a different pigment.\u003c\/p\u003e\n\u003ch2\u003eSafety\u003c\/h2\u003e\n\u003cp\u003eContains lead (lead oxide): toxic if swallowed or inhaled, may damage the unborn child and is suspected of damaging fertility, and may cause organ damage through prolonged or repeated exposure. Not for use by children or during pregnancy. 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 massicot a natural pigment?\u003c\/h3\u003e\n\u003cp\u003eMassicot also exists as a natural mineral, but only in small quantities. Pigment-grade yellow lead oxide is manufactured by heating lead or lead compounds, so it is a synthetic pigment.\u003c\/p\u003e\n\u003ch3\u003eWhat is the difference between massicot and lead-tin yellow?\u003c\/h3\u003e\n\u003cp\u003eMassicot is lead oxide alone; lead-tin yellow is lead stannate, made by heating lead and tin oxides together. Lead-tin yellow was far more widely used by the old masters.\u003c\/p\u003e","brand":"COLIBRI PIGMENTS LLC","offers":[{"title":"50g","offer_id":43243861999863,"sku":"","price":4.9,"currency_code":"USD","in_stock":true},{"title":"1kg","offer_id":43243862032631,"sku":"","price":85.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0643\/6696\/9079\/files\/massicot_c7366c32-7d7c-40df-9c28-340340a32f65.jpg?v=1793366938","url":"https:\/\/colibripigments.com\/products\/massicot","provider":"Colibri Pigments","version":"1.0","type":"link"}
