The Nerd’s Guide to Mordants!

This is the nerd’s guide to mordants – what they are, why they are important and how they are used in natural dyeing.  Everyone wants to create long-lasting and beautiful plant color and the best way to do that is to mordant properly.  The class will experiment with the most popular plant-based tannins and alum accumulators, mineral salt mordants and other binders to see the effects on animal and plant fibers. Each mordant variable will be dyed so that we can see results and we will build a reference folio for students to take with them as a record of their experiments. The class will work with cotton, linen, hemp, silk and wool fabric with enough fabric left over for future experiments, comparisons and creativity.  This workshop is open to all levels.

Through our experiments, we will gain insight into the relationship between the mordant, the dye and other ways we can coax color onto cloth.  At the conclusion of the workshop, students will have a clear understanding of which mordant to use, and when to follow the rules and when to bend them a bit. We will emphasize how to use mordants safely and why we avoid certain mordants and if there is a safer alternative.
