Continuing in dyeing experiments with Marian this time we went for a more colorful dye plant – madder roots. Madder (Rubia Tinctorum) is one of the most ancient dyes and there is plenty of literature as well as information on the web on how to dye both protein and vegetable fibres.
All literature says to keep the temperature well bellow boiling point to achieve red or salmon pink or terracotta orange/red instead of brown, so did I. I have used cca 30 g of madder powder per 190 g of fibres in total and have had them in the bath for around a week, keeping temperature anywhere ,between 40 to 80 C. The protein fibres, as usual, are the darkest, the palest is tencel/lyocell and banana fibre. All fibres were mordanted in the same way as those dyed with alkanet and logwood.

all vegetable fibres: lyocell, banana fibre, hemp, linen, bamboo, viscose, ramie (clockwise, starting from lyocell the palest)
all protein fibres, from left: merino wool, tussh silk noil, tussah silk nepps, mulberry silk, trowster silk
