OBS: [...] le pigment [est] un type particulier de colorant. Le pigment se fixe à la surface de l'objet visé. Le tout après broyage et avec l'aide d'un liant plus ou moins fluide tel que l'huile.

CONT: Recipes for Organic Indigo Vats[.] Try different combinations or experiment with local plants and fruits. For example, we have found mixing two organic reducing agents, such as henna and fructose, gives a strong indigo vat. These vats give the best results if they are made the day before dyeing. ... Remember to cover your vat when not in use. These organic vats were originally developed by Michel Garcia, a botanist and dye chemist with a deep knowledge of how colour behaves on the molecular level. The recipes outlined here were developed by him to create efficient indigo vats using eco-friendly ingredients.
