{"product_id":"procraft-silver-oxidizer-16oz","title":"Procraft Silver Oxidizer-16 oz.","description":"\u003cp\u003eProcraft Silver Oxidizer is a non-corrosive solution designed to blacken silver or copper when applied at full strength. When diluted with water, the oxidizing action slows, allowing precise control over the resulting color — from deep black to all shades of gray. No heating is required; the solution works effectively at room temperature, making it a straightforward addition to any finishing workflow.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNon-corrosive formula safe for use on silver and copper\u003c\/li\u003e\n\u003cli\u003eFull-strength application produces rich black oxidation\u003c\/li\u003e\n\u003cli\u003eDilute with water to slow the reaction and achieve gray tones\u003c\/li\u003e\n\u003cli\u003eWorks at room temperature — no heating necessary\u003c\/li\u003e\n\u003cli\u003eAllows controlled, repeatable surface coloring results\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSize\u003c\/th\u003e\n\u003ctd\u003e16 oz.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eApplication\u003c\/th\u003e\n\u003ctd\u003eSilver and copper oxidizing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eUse Temperature\u003c\/th\u003e\n\u003ctd\u003eRoom temperature (no heating required)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDilution\u003c\/th\u003e\n\u003ctd\u003eUse full strength for black; dilute with water for gray tones\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eNotes\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eShipping Restrictions — Hazardous Item:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eGround shipping only via UPS.\u003c\/strong\u003e \u003cem\u003eNo air service, no USPS mail, and no UPS 3-Day, 2nd Day Air, or Next Day Air.\u003c\/em\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUSA only.\u003c\/strong\u003e \u003cem\u003eThis item cannot be shipped outside the United States.\u003c\/em\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Grobet USA","offers":[{"title":"Default Title","offer_id":43580121514198,"sku":"145.682","price":58.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/procraft-silver-oxidizer-16-oz-otto-frei.jpg?v=1719958222","url":"https:\/\/www.ottofrei.com\/it\/products\/procraft-silver-oxidizer-16oz","provider":"Otto Frei","version":"1.0","type":"link"}
