Kakishibu Dye (Persimmon Tannin) Natural dyes are fascinating because we can see the history of human curiosity and imagination as it interacts with the natural world. Like, who looked at a hard, green, horribly astringent, inedible persimmon fruit and thought “You know, there’s probably an amazing, insect-repelling, anti-microbial, water-resistant, beautiful color in there if I just ferment it for a couple of years with a slice of eggplant.” Who, exactly? Whoever that clever person was, we have them … 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

Mordant Monday: Middle Mordant in Toronto

Thank you to Rachel MacHenry and Gitte Hansen of Contemporary Textile Studio Co-operative for the lovely photos! I taught a one day workshop on middle mordant using Japanese dyes in Toronto on Friday, and had a great time with the students. This was the first time we’d tried the technique using only Japanese dyes that we extracted, and we also had a side trip into kakishibu which didn’t require any mordant, but made a beautiful shade. I’ve written about middle mordanting before: Catharine Ellis has a nice recipe and procedure in her book and Studio Notes, and I’ve also seen … Read more

A Humble, Ingenious Leaf Mordant: Symplocos

The plant world contains species that draw alum from the soil and store them in their tissue – they’re referred to as alum accumulators or hyper accumulators. There’s a plant species called symplocos that is an alum accumulator and contains enough alum to be used as a plant-based mordant. We carry symplocos and are happy to have a new shipment arriving this week, so it’s a good time to review this mordant alternative with a great backstory. The Story of Symplocos In 2005 and 2006, The Bebali Foundation (a partner enterprise to Threads of Life that focuses on sustainable economic … Read more

Mordant Monday: Overdyeing: Indigo First, or Indigo Second?

Indigo first, or indigo second? We get mordant questions all the time at Botanical Colors so why not create Mordant Monday??? Got mordanting questions? Email [email protected] YOU ASKED: Do you always dye indigo first before overdyeing with another color? Does it make any difference? KATHY ANSWERED: When I was starting out, I was advised to dye with indigo first, rinse, mordant my fabric, and then dye with a mordant color second in order to create any type of compound color when indigo is involved. We largely agree with this as most of our production colors start with an indigo shade … Read more
