Botanical Colors Aquarelle liquid natural dye extracts

Liquid Madder natural dye extract

Madder is one of our oldest dyestuffs with archaeological finds of madder dyed fibre being traced back at least as far as 3BCE. Madder can be found growing in many countries from Europe to Iran and the Middle East but also parts of Africa and Australia. Although madder contains many complex colour chemicals, it is the chemical alizarin, found in the plant’s roots that produces the characteristic red shades.

For the best reds, use an alum mordant on protein fibres (aluminium actetate on plant fibres) and alkaline (hard) water. Pre-test the pH of your water and if it is below 8, add a little sodium carbonate or similar alkali to your dyebath. Keep the dyebath below 70°C as above that temperature the dyebath will shift towards orange/browns.

For oranges and orange/browns use a mild acid such as vinegar or citric acid to reduce the pH of the dyebath to 6 or below. Raising the dyebath temperature above 70°C will shift the colours towards rust-browns.

50 grams of Liquid Madder will dye about 500 grams of fibre or yarn to a deep shade and around 1kg of yarn or fibre to a medium shade.

Price: £10.00 per 42ml (50g) [item code DY502]
