Soymilk as a Printing Binder for Mordant Monday

Soymilk as a printing binder In today’s Mordant Monday (excuse the awful pun – I found it online), we check out how to use soy as a binder for natural dyes and pigments. Before the widespread use of acrylic paints and mediums, artists had ingredients from the natural world to use for painting and printing on paper and canvas. They used a wide range of natural binders including tree sap, milk, egg, oils, minerals and other substances that helped pigments stay attached to substrates. In Japan, soybeans are the most common binder for textile work, and it serves as a … Read more

Mordant Monday: A Great Red with Madder Extract

My notes on how to make a great red. Madder extract is the perfect ingredient for a beautiful, vibrant red that almost glows because it has a gorgeous golden undertone. Sometimes the color veers toward a winey burgundy (equally beautiful), but I wanted to get almost a glowing ember feel to this yarn. To so this, I used a little bit less madder and the minimum amount of calcium carbonate. Here’s how I did it. Materials Instructions Where’s the Cream of Tartar? Cream of tartar is a great mordant additive for dyeing as it helps keep wool soft and assists … Read more

Mordant Monday: Why so Many Alums?

For today’s Mordant Monday, We are revisiting a great question: All those alums?! Why so many alums? You Asked: Hello, I am wondering if it is possible to use Ammonium Aluminum Sulfate for mordanting wool? I am finding this substance in the spice section ofthe grocery store. I can’t seem to find definitive information about this and I feel confused about all the different “alums” that exist.  We answered: The different alum types are basically the same mineral but they are refined differently for different purposes using a variety of chemicals. They can look different, too. For protein fibers, aluminum … Read more

Mordant Monday: We stand with Minnesota and Maine

Botanical Colors is an immigrant company. I experienced hearing the stories of my mother and father who were stripped of their constitutional rights and incarcerated for three years in US concentration camps during World War II. They were US citizens. They too, were taken away and “detained” because the government didn’t like the way they looked and where they came from. The events occurring in Minnesota and Maine (and not to forget LA, Chicago, and other US cities) are profoundly disturbing to me. Botanical Colors stands in fierce, grieving solidarity with our communities in Minnesota and Maine who are facing escalating … Read more

Any suggestions how to avoid staining all material grey?? KATHY … Read more

MORDANT MONDAY: How To Reuse A Tannin Bath

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’m wondering if its possible to reuse a tannin bath, perhaps by using half as much tannin powder the second time as one can do when re using a mordant bath? Recently I have made a tannin bath for linen and have lots left over, it would be great not to throw it out! Secondly, I usually rinse the fabric after mordanting and before dyeing- is this correct? KATHY ANSWERED: I think recharging and reusing tannin baths … Read more

Q & A: Round Up of Scouring + Mordanting 101

Mordanting and scouring should be at the top of your things-to-do list before natural dyeing. Botanical Colors Founder Kathy Hattori recently took on as many questions as was humanly possible to clarify the processes. Before reading, also please see our How-To Scour and How-To Mordant pages. Scouring Questions If I use untreated and unbleached fabric, is it a must to scour the fabric or is washing it enough? If you mean by “untreated” that it has never been scoured, then you should scour. If untreated and unbleached means it is also prepared for dyeing (PFD or RFD), then you can … Read more
