Mordant Monday: Dyes of The Américas

One of the first dyes that I ever encountered was cochineal, and although I was surprised that it came from an insect, I was also in love with its beautiful color.  Cochineal was the most important natural dye to originate from Oaxacan indigenous culture that still has great value and a global impact today. When Spanish colonizers realized the value of this dye, they created plantations and exploited indigenous labor to process up to 300,000 pounds of cochineal for export per year. It was one of the most precious colors and brought great wealth to the Spanish crown. Being in … Read more

Mordant Monday: Dyeing without a mordant

This Mordant Monday, I want to share a little bit about my pokeberry dye adventure this past week. Those of you who know me know that I was trained to mordant nearly everything (exception: indigo). Not mordanting something that needs a mordant usually elicits a shocked, silent, but oh-so-judgey raised eyebrow, so this post is a stretch for me. The interesting thing about pokeberries is that it’s possible to get a brilliant color by using wool yarn and white vinegar. No alum mordant is used in this technique. And vinegar is not normally considered a mordant. So here we are. … Read more

MORDANT MONDAY: Indigo & Discharging Mordants

We get mordant questions all the time at Botanical Colors so why not create Mordant Monday??? Got mordanting questions? Email [email protected] YOU ASKED: My question involves the processes of indigo dyeing when combined with other plant dyes that have been mordanted with aluminum acetate. My understanding is that citric acid discharges the mordant and also neutralizes the alkalinity of indigo as a last step in finishing indigo dyed cloth. How would you go about neutralizing indigo without discharging mordant? For some processes, I am wanting to use indigo on top of other colors rather than underneath. Can vinegar be used … Read more

Make An Easy, Organic Indigo Vat

In 2009 and 2010 I had the opportunity to study with natural dye master Michel Garcia.  He is a marvelous and knowledgeable teacher,  fascinated with using the chemistry of simple ingredients to create natural colors.  One of the things that he demonstrated to us was to be fearless about the indigo fermentation vat.  What a gift!  For me, the indigo fermentation vat has always been a mystery and I could never quite figure out all the details so I never pursued it.  I was getting great and consistent color with my lye and soda ash and chemical reducing agents, so why … Read more

Mordant Monday: Chestnut, Fustic, Iron and Indigo

This week’s Mordant Monday focuses on Chestnut. We used Chestnut extract in our gradation and absolutely loved the combination of Chestnut, Fustic and Iron with Indigo. This gradation is slightly different than our previous experiments. This time I did not overdye with a warm shade like Madder, to get corals and pinks. I wanted to focus on green and blue. Like previous examples, when a tannin is combined with other colors you can get exciting mixes and beautiful color blends that harmonize and are perfect for patchwork, creating gradations and stitching. If you are a yarn person, many of these … Read more

Mordant Monday: Walnut, Madder, Iron and Indigo

Black Walnut Juglans nigra is one of our most interesting tannins and it’s a color that’s native to the North American continent. The entire tree contains color but it is in the green hulls that we find a strong concentration of dark tannins yield light beige to golden brown on cellulose. On wool, black walnut really shines and makes a rich brown shade. Walnut Hull Powder from black walnut (Juglans nigra) is a common source of brown dye throughout North America. The fleshy hulls are full of tannin, juglone and other pigments and are the primary source of the dye. … Read more

MORDANT MONDAY: Will Mordant Affect Indigo Dyeing?

We get mordant questions all the time at Botanical Colors so why not create Mordant Monday??? Got mordanting questions? Email [email protected] YOU ASKED: I use aluminum triformate as my mordant for cellulose and silk. I am planning to dye linen with weld and was told that I didn’t need to use a tannin before dyeing if using potassium triformate.If I do need to use a tannin and have already mordanted the linen, do I go back and use tannin and remordant? KATHY ANSWERED: I have concentrated on using a tannin pretreat with aluminum sulfate and haven’t done so as frequently … Read more
