{"product_id":"sea-shell-white-pigment-oyster-shell","title":"Sea Shell White Pigment (Oyster Shell)","description":"\u003cp\u003eSea Shell White is a handmade natural white pigment ground from oyster shells, made of calcium carbonate. It produces a soft, slightly warm white with a gentle pearly luminosity and a smooth, velvety texture when finely ground. It is also the same material as Japanese gofun, the shell white used for centuries in nihonga painting, dolls, and lacquerwork.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eIn use, Sea Shell White gives soft, luminous whites, pale tints and grounds in glue based paints, watercolor, gouache and tempera. It is less opaque than titanium or lead white, so it brightens and softens colors without flattening or dulling them. It handles beautifully with animal glue binders and makes a lovely natural extender in encaustic and gesso. In oil it becomes largely transparent. It is stable and lightfast, but sensitive to acids.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003eHistory\u003c\/p\u003e\u003cp\u003eShell whites have been used in East Asian painting for over a thousand years. In Japan, gofun originally meant lead white, but from around the 15th century it came to mean shell white made from weathered oyster, clam and scallop shells, which were aged outdoors, crushed, ground and levigated. Gofun became the essential white of nihonga painting, traditional dolls, lacquer and Noh masks, valued for its soft luminosity and gentle texture.\u003c\/p\u003e\u003cbr\u003e\u003cp\u003ePigment Information\u003c\/p\u003e\u003cp\u003ePigment Type: Natural (Organic origin, inorganic composition) calcium carbonate from oyster shell\u003c\/p\u003e\u003cp\u003eSource: Oyster shell (calcite, CaCO₃), cleaned and ground\u003c\/p\u003e\u003cp\u003eOrigin: U.S.A.\u003c\/p\u003e\u003cp\u003eSuitable Mediums: Glue \/ Distemper, Watercolor, Gouache, Tempera, Casein, Fresco \/ Lime, Encaustic, Acrylic; in oil as a transparent extender\u003c\/p\u003e\u003cp\u003eLightfastness: Excellent\u003c\/p\u003e\u003cp\u003eOpacity: Semi-opaque in water based media, transparent in oil\u003c\/p\u003e\u003cp\u003eOther Names: Gofun, Oyster Shell White, Shell White, Hakuai\u003c\/p\u003e\u003cp\u003eColor Index Code: PW18\u003c\/p\u003e\u003cp\u003eHealth and Safety\u003cbr\u003eFor art use only.
