When used in small amounts, it can transform colours toward deeper greens, teals and rich browns, adding depth and complexity to natural dye results. It is most commonly used as an after-bath or modifier, rather than a primary mordant, allowing dyers to fine-tune colour after the initial dyeing process. This makes it particularly useful for achieving subtle tonal variations and more controlled, refined outcomes.\u003c\/p\u003e\n\u003cp\u003eThis laboratory-refined grade offers consistent and reliable performance, making it suitable for professional textile applications where precision matters. It can be used on a range of natural fibres including cotton, wool and silk, though care should be taken with quantities to avoid over-modification.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eBenefits\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eModifies colours to deeper greens, teals and browns\u003c\/li\u003e\n\u003cli\u003eEnhances depth and complexity of natural dye results\u003c\/li\u003e\n\u003cli\u003eCan improve washfastness when used correctly\u003c\/li\u003e\n\u003cli\u003eIdeal for controlled, subtle colour adjustments\u003c\/li\u003e\n\u003cli\u003eConsistent, high-quality refined product\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePerfect For\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eColour modification in natural dye projects\u003c\/li\u003e\n\u003cli\u003eBotanical dyeing on cotton, silk and wool\u003c\/li\u003e\n\u003cli\u003eAdvanced studio work and professional workshops\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTechnical\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eHigh-purity copper sulphate powder for controlled colour modification\u003c\/li\u003e\n\u003cli\u003eAlters hues and enhances fastness in natural dye work\u003c\/li\u003e\n\u003cli\u003eUse sparingly (typically 1–2% of fabric weight)\u003c\/li\u003e\n\u003cli\u003eCan be applied in separate bath or as a post-dye treatment\u003c\/li\u003e\n\u003cli\u003eAlways wear gloves and avoid prolonged skin contact\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Kraftkolour","offers":[{"title":"Default Title","offer_id":51912859812104,"sku":"L.ND.COPSUL","price":5.8,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0961\/2345\/3704\/files\/mordant.coppersulphate1.jpg?v=1773836013","url":"https:\/\/winghamwoolwork.co.uk\/products\/mordant-copper-sulphate","provider":"Wingham Wool","version":"1.0","type":"link"}
