Mordant Monday: Gallo Tannin, Fustic and Madder Gradation

This week’s Mordant Monday focuses on Gallo Tannin, also known as Oak Gall tannin, or Oak Galls. We used the extract made from Oak Galls in our gradation, but a similar result comes from oak galls that have been crushed or pulverized. Gallo Tannin is one of the ancient tannins with many uses, including making black ink, leather tanning, and in traditional Asian medicine. It is the most commonly used tannin when mordanting with tannin + alum, as the color it imparts is very light, and it doesn’t show a strong undertone, like sumac or walnut or other tannins with … Read more

Natural vs. Synthetic Dyes: The (Ill-Informed) Battle Continues

  Botanical Colors founder Kathy Hattori recently commented on an article titled “Mordant Madness!” on Buxton, Maine based Lana Plantae responding to a discussion about a person posting on a “social media page devoted to fiber arts,” that they were “attacked” by natural dyers at a fiber event because their wool was colored with synthetic vs. using natural dyes. Lana Plantae founder Marcia Macdonald writes: “I do suspect the word “attack” may be a little strong and used for dramatic effect. Immediately there was a long string of commentary and it was very anti- natural dye, anti-mordant and overwhelmingly these … Read more

Mordant Monday: Spotlight on Sumac

Sumac is from the Rhus genus and its scientific name is Rhus coriaria. It’s native to southern Europe and western Asia where it is commonly known as Tanner’s Sumac or Sicilian Sumac. We are fortunate to have number of North American native sumac including Rhus glaubra, sometimes called Smooth Sumac, and Rhus typhina or Staghorn Sumac, known for its dramatic bright red berry clusters. The staghorn berries were used by indigenous people as a tea, and the bark, branches, … Read more

Mordant Monday: Spotlight on Quebracho Moreno

Today in our tannin series we move on to Quebracho Moreno. Quebracho (Schinopsis balansae and Schinopsis lorentzii) is an evergreen tree that grows wild in South America. It grows mainly in Argentina and Paraguay in dense sub-tropical forests which also include a variety of other trees and vegetation. The name is due to its hardness, and comes from two Spanish words, quebrar and hacha, meaning “axe breaker”.

MORDANT MONDAY: Exhausted Mordant Baths + Sumac 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: After watching your video about aluminum triformate I decided to order it and started using it. I work with large quantities and large pieces, so I prepared a bucket with 50 liters of water and 500 grams of aluminum triformate. I used it to mordant approximately 5 kg of yarn/pieces. The water was white at the beginning, I suppose because I just mixed the powder, but after the first load, it was just like regular water. I … Read more
