Made from 100% pure crystalline fruit sugar, it offers a gentle, eco-friendly alternative to synthetic reducers such as sodium hydrosulphite, allowing indigo to be reduced and used without harsh chemicals.\u003c\/p\u003e\n\u003cp\u003eIn an indigo vat, fructose works by gradually consuming oxygen, enabling the indigo pigment to convert into its soluble “leuco” form. This process creates a stable, easy-to-manage vat that produces rich, lasting blues without releasing harmful by-products. Fructose is widely used in so-called “1-2-3 vats” (one part indigo, two parts lime, three parts fructose), which are known for being reliable, low-odour, and straightforward to maintain. It performs consistently with both natural indigo and woad, and is suitable for dyeing a wide range of fibres including wool, silk, cotton and linen.\u003c\/p\u003e\n\u003cp\u003eFavoured by both beginners and experienced dyers, fructose vats offer a controlled, sustainable approach to indigo dyeing, making them ideal for home studios, workshops and educational settings.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNatural, non-toxic alternative to synthetic reducing agents\u003c\/li\u003e\n\u003cli\u003eCreates stable, easy-to-control indigo vats\u003c\/li\u003e\n\u003cli\u003eSupports long-lasting vats with minimal maintenance\u003c\/li\u003e\n\u003cli\u003eOdourless and suitable for indoor use\u003c\/li\u003e\n\u003cli\u003eProduces strong, vibrant blue tones without chemical runoff\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePerfect For\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNatural indigo or woad dye vats\u003c\/li\u003e\n\u003cli\u003eEco-textile and sustainable fashion studios\u003c\/li\u003e\n\u003cli\u003eEducational workshops and home dyeing setups\u003c\/li\u003e\n\u003cli\u003eTraditional indigo dyeing and craft production\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e100% pure crystalline fructose for natural indigo reduction.\u003c\/li\u003e\n\u003cli\u003eNon-toxic, biodegradable, and food-grade safe.\u003c\/li\u003e\n\u003cli\u003eUsed in 1-2-3 indigo vat formula (1:2:3 ratio with lime and indigo).\u003c\/li\u003e\n\u003cli\u003eCompatible with indigofera, woad, or natural indigo extracts.\u003c\/li\u003e\n\u003cli\u003eMaintains steady vat reduction without strong odours or fumes.\u003c\/li\u003e\n\u003cli\u003eIdeal vat temperature: 40–50°C for optimal reduction.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Kraftkolour","offers":[{"title":"Default Title","offer_id":51912860008712,"sku":"L.ND.FRUC","price":4.25,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/2345\/3704\/files\/mordant.fructose1.jpg?v=1773835767","url":"https:\/\/winghamwoolwork.co.uk\/products\/mordant-fructose","provider":"Wingham Wool","version":"1.0","type":"link"}
