Dyebaths which use less dyestuff  yield peach, coral, and dusty rose, while higher concentrations of dye develop into brick red, terracotta and deep wine tones. The dye contains multiple color-bearing compounds, including alizarin and purpurin, which respond differently to both temperature and pH. Heating a madder bath above 160 degrees F will bring out more tannins and yield a more brown dye result. Alkaline dye baths using soda ash or calcium tend to enhance deeper reds, while acidic dyebaths using vinegar or citric acid will encourage softer orange tones. Madder is also known for its layering ability, allowing dyers to create nuanced tonal variation through gradual buildup rather than flat saturation.\u003c\/span\u003e\u003c\/p\u003e","brand":"Dharma Trading INC","offers":[{"title":"100 grams","offer_id":48493299237118,"sku":null,"price":10.5,"currency_code":"USD","in_stock":true},{"title":"250 grams","offer_id":48493299269886,"sku":null,"price":24.5,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1160\/7736\/files\/Screenshot2026-06-29at3.35.38PM.png?v=1782761846","url":"https:\/\/red-stone-glen-fiber-arts-center.myshopify.com\/products\/madder","provider":"Red Stone Glen Fiber Arts Center","version":"1.0","type":"link"}
