Unlike traditional mordants that bind dye to fibres, calcium carbonate works as a pH modifier, creating a more alkaline environment that can shift and enhance the tones of natural dyes. It is especially useful when working with plant-based dyes where subtle changes in pH can dramatically alter final colours.\u003c\/span\u003e\u003c\/p\u003e","brand":"Earth Kind Crafts","offers":[{"title":"Default Title","offer_id":52991423185238,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":false}],"url":"https:\/\/earthkindcraftsupplies.com\/products\/calcium-carbonate-modifier","provider":"Earth Kind Crafts","version":"1.0","type":"link"}
