Blog — Violet Dye Co
Craft guides, tutorials, and inspiration for natural fabric dyeing and artisan soap making with Mimosa Hostilis root bark (Mimosa tenuiflora / Tepezcohuite).
Mimosa Hostilis inner root bark is one of the most colour-rich natural dye sources available to craft dyers today. Sustainably sourced from Mexico, it produces a wide spectrum of results depending on mordant choice, pH, fiber type, and preparation method — from dusty mauves and warm tans through deep burgundy, slate gray, and near-violet. This blog covers the practical and technical side of working with MHRB: how to prepare a dye bath from chips, shredded bark, or powder; which mordants shift which colours; and how to incorporate root bark powder as a natural colorant in cold process soap.
Topics covered include mordanting with alum, iron, copper, and tannin; achieving consistent colour on cotton, wool, silk, and linen; the differences between Mexican and Brazilian Mimosa Hostilis; and the deeper history of natural colour — from Tyrian purple to contemporary botanical craft. Whether you are new to natural dyeing or an experienced maker looking to refine your technique, these guides are written for people who work with their hands and want to understand the why behind every result.
