{"product_id":"libethenite-blue-pigment","title":"Libethenite Blue Pigment","description":"\u003cp\u003eDescription\u003cbr\u003eLibethenite Blue is a handmade synthetic mineral libethenite, a copper phosphate mineral (Cu₂(PO₄)(OH)). It produces a vibrant, slightly cool blue with a crystalline, granular texture and a soft mineral depth that lightens as it is ground finer.\u003c\/p\u003e\n\u003cp\u003eIn use, Libethenite gives rich, mineral blues for skies, water, drapery and decorative work, with the gentle granulation of a ground crystal. It mixes with earths for muted, natural greens and with yellows for warmer foliage tones. As a copper mineral, it should be kept away from strong acids and sulfur containing pigments.\u003c\/p\u003e\n\u003cp\u003eHistory\u003cbr\u003eLibethenite was named in 1823 after the mining town of Libethen in Slovakia, now Ľubietová, where it was first found in the copper mines. Copper phosphate minerals such as libethenite and pseudomalachite have occasionally been identified in historical paintings alongside malachite, but they are far rarer. Today libethenite is typically a collector's mineral, and as a pigment it offers a rare copper blue.\u003c\/p\u003e\n\u003cp\u003ePigment Information\u003cbr\u003ePigment Type: Synthetic (Inorganic) copper phosphate mineral\u003cbr\u003eSource: Synthetic libethenite (Cu₂(PO₄)(OH))\u003cbr\u003eOrigin: U.S.A.\u003cbr\u003eSuitable Mediums: Watercolor, Gouache, Tempera, Casein, Acrylic, Encaustic, Oil\u003cbr\u003eLightfastness: Excellent\u003cbr\u003eOpacity: Semi-transparent\u003cbr\u003eOther Names: Copper Phosphate Blue, Synthetic Libethenite\u003cbr\u003eColor Index Code: N\/A\u003c\/p\u003e\n\u003cp\u003eHealth and Safety\u003cbr\u003eFor art use only.
