Email [email protected] YOU ASKED: Do you always dye indigo first before overdyeing with another color? Does it make any difference?

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.

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

We had a question come in earlier this week about the differences in the variety of alum mordants we offer. Katie asks: 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.
