[31] This black was created using a recipe of dyeing the textile first in woad, then mordanting it with alum and sour water, and boiling it in madder for several hours. It produced a beautiful, uniform black, Noir de flandres. This recipe was reproduced in the colour reconstruction workshop at Aalto University, 19-21 September, 2019, with Natalia Ortega-Saez, Jo Kirby and Sophie Pitman. I thank Jenny Boulboullè and Natalia Ortega Saez for the recipe.
