FEEDBACK FRIDAY: Mordanting Roundup

This week: Weeks worth of mordanting questions melded into one FEEDBACK FRIDAY!

Each week, we are emailed with questions from our natural dye community asking simple and complex questions that we thought might be worth sharing. This week, we thought we’d curate as many mordanting questions as we could pull from FEEDBACK FRIDAY’s past to give you something worth bookmarking.

Of course, all of your burning questions about mordanting answered by natural dyer in chief, Kathy Hattori, Founder of Botanical Colors:

Do I need to heat mordant up?

Must I mordant if I am dyeing with plants gathered in my yard?

My alum mordant solution is cloudy.  Why?

What is the best natural fixative for cotton?

Do I need to mordant for indigo?

Do I need to remordant previously mordanted wool?

What is the best mordant for cotton lint?

Is there a mordant that I can harvest instead of using aluminum acetate?

When dyeing linen or cotton, is it better to use aluminum acetate or sulfate to bond the color?

I was wondering with iron can you make a big batch of it and use as needed like for an afterbath/mordant/assist/etc at your own discretion or do iron solutions need to be made fresh each time?
