MORDANT MONDAY: Do I Need To Mordant When Using Liquid Tannin?

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 am using your liquid tannin on cotton. Beyond scouring, I was wondering if it is sufficient to use liquid tannin (on cotton t-shirts) as a mordant before using the other liquid dyes?

Tannin and Alum Mordant Experiments

I’m obsessed with using tannin and aluminum sulfate to create different color bases for both natural dyes and indigo. What I love about this technique is that this is a great mordant option and it’s a lot of fun to see the colors develop and take on the subtle differences between the different tannin bases. This time, we’re working with a lightweight, pre-mordanted, organic cotton suitable for stitching and quilting. We mordanted 4 fat quarters, each with a different tannin, and then tried a few dye experiments using Marigold Mix, Madder extract and Indigo. Start with our Mordanted Fat quarter … Read more

Mordant Monday: Foraging Instead

Today I was supposed to write about mordanting, but I had a foraging date to scout out potential sites for our upcoming workshop with Julie Beeler, so I headed out this morning to get a sense of what we might discover during our workshop. I am a mushroom foraging novice, and will stare for a long time at the forest floor and see absolutely nothing. I simply don’t have the eyes yet to distinguish between a brown leaf and a bolete. But to my surprise, there were some mushrooms that give color that very happily announced their presence right in … Read more

Mordant Monday: Tannin Extravaganza!

TANNIN A TIMELESS MORDANT Tannins are a bitter and astringent compound found so abundantly in many plants. In food, they serve as the slight pucker in black coffee and tea, and the “oaky” flavor in aged wines. Tannins are used in medicine and for leather tanning. For us, they are the natural dyer’s not-so-secret-weapon to beautiful color. For the natural colorist, tannins provide a rich base for unusual and eye-catching combinations, and they’re particularly effective on plant fibers such as cotton and linen. We have two back to back tannin workshops for you coming up in January! Build your swatch … Read more
