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?

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 that we dip. We seem … Read more

Mordant Monday: Does Indigo Damage Mordants

We get mordant questions all the time at Botanical Colors so why not create Mordant Monday??? Got mordanting questions? Email [email protected] 2 light indigo dips on mordanted silk before immersing in exhaust dye baths to make pastels 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 … Read more

Mordant Monday: What is Dunging?

Cellulose fibers are the most common fiber that we start with as cotton fabric is readily available and affordable. However, cotton does not have the same affinity for natural dyes as protein fibers such as wool, so the cellulose mordant process is different to achieve good results. The mordant process for cellulose fibers includes pretreating with a tannin, then immersing the tannin treated fabric into an alum solution. This method is one of the earliest mordant methods for cellulose fibers and produces very good results. We use this method regularly as we also love to experiment with different tannins to … Read more

First things first, let’s talk about health & safety: We always recommend working in a very well ventilated area. Although natural dyes are non-toxic, when using fine powders it’s best to wear a mask, and keep the windows open. Be mindful around little ones and pets as you don’t want anything going in mouths that shouldn’t be there. Also, when beginning to set … Read more
