{"product_id":"goethite-pigment","title":"Goethite Pigment","description":"\u003cp\u003eGoethite is a handmade natural pigment ground from the mineral goethite, a hydrated iron oxide (FeO(OH)). It is the coloring mineral behind yellow ochres, but in its pure mineral form it gives a deeper, more saturated yellow with a dense, earthy tone. It is opaque to semi-opaque, lightfast and extremely stable.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eIn use, Goethite gives warm yellows and deep golden earths ideal for landscapes, shadows, wood and stone, and warm underpainting. It mixes with blues for strong greens, with reds for rich, warm oranges and with white for soft, natural tans. When heated it turns red as it converts to hematite, the same process that turns raw sienna into burnt sienna.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eHistory\u003c\/p\u003e\u003cp\u003eGoethite has been used as a pigment since prehistory as the main colorant in yellow ochres. The mineral itself was named in 1806 after the German poet and scientist Johann Wolfgang von Goethe, who had a keen interest in mineralogy and color. As a pure mineral pigment it offers painters the essence of the ochres in a deeper, more concentrated form.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003ePigment Information\u003c\/p\u003e\u003cp\u003ePigment Type: Natural (Iron Oxide) mineral (Goethite, FeO(OH))\u003cbr\u003eSource: Natural goethite, crushed and ground\u003cbr\u003eOrigin: U.S.A.\u003cbr\u003eSuitable Mediums: Watercolor, Oil, Tempera, Acrylic, Encaustic, Cold Wax, Casein, Lime \/ Fresco\u003cbr\u003eLightfastness: Excellent\u003cbr\u003eOpacity: Semi-opaque to opaque\u003cbr\u003eOther Names: Mineral Yellow Brown, Needle Iron Ore, Brown Iron Ore\u003cbr\u003eColor Index Code: PY43\u003c\/p\u003e\u003cp\u003eHealth and Safety\u003c\/p\u003e\u003cp\u003eFor art use only.
