{"product_id":"sepp-rottenstone","title":"Rottenstone","description":"\u003cp\u003eDecomposed limestone creates antiquing effects that feel genuinely aged rather than artificially distressed. Sepp Rottenstone polishes metal surfaces to subtle luster while revealing the underlying structure of water-gilded work, exposing bole layers and lay lines that suggest centuries of handling and wear. The fine gray powder settles naturally into recesses and along edges where genuine patina would accumulate.\u003c\/p\u003e\n\u003cp\u003eTraditional gilders use rottenstone to break the perfection of freshly laid gold leaf, creating depth and visual interest through controlled distressing. The material's natural gray tone mimics accumulated dust and oxidation without the harshness of black or brown antiquing agents. On metals, it produces a soft polish that enhances rather than obscures the base material's character.\u003c\/p\u003e\n\u003cp\u003eApply dry with soft brushes to control placement, or mix with binding mediums for more permanent effects. The powder's fine consistency allows precise application, heavy in areas that would naturally see wear, lighter elsewhere to maintain the illusion of authentic aging. Gilders working on restoration projects and decorative artists creating period-appropriate finishes both rely on rottenstone for results that respect historical precedent while meeting contemporary standards.\u003c\/p\u003e","brand":"Sepp","offers":[{"title":"5 oz. jar","offer_id":47979710054629,"sku":"77134","price":14.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.texasart.mom\/products\/sepp-rottenstone","provider":"Texas Art Supply","version":"1.0","type":"link"}
