Natural Dye Basics: Scouring and Mordanting - Shared screen with speaker view
Laura Berkowitz Gilbert
I've seen some instructions for scouring cellulose fiber that say to just use soda ash. So I'm wondering what the Cellulose Scour adds to the process?
Ok good lord ask Kathy new questions!!
When is it important to use a tannin as part of the mordant process on cellulose fibers?
.Can you please go over the ideal temperature ranges for scouring and mordanting of various fiber types? I feel like I see conflicting information about which fiber is best mordanted at lower or higher temperatures.
Can you please explain the scouring process - you said we HAVE to do it, but didn’t say exactly how :-)
I want to use tannin and alum sulfate on cellulose, will I still get good color?
To clarify… for cotton, linen, silk… can we scour and mordant, dry and store the fabrics?
Perhaps I fell asleep, but how do you scour?

I m very new here so wanted to know if there's a detailed blog for mordanting?
What is a good scour for repurposed garments?
If I am using the "tannin/alum" mordant method, when would I use chalk? Is there a benefit to ending in a tannin bath?
Can you talk about the safety measures needed when using iron?
Is there any advantage to double mordanting with alum? E.g. to complete the process twice
Will there be a part 2 addressing cellulosic fibers? Would love to learn more about working with cottons & linens
whats the deal with using an aluminum pot as a mordant?
Any recommendations about how to scour wool top? It’s fragile.
I only use cotton, for cellulose, what are your top 5 mordants to use?
Do you mordant and then post mordant with calcium carbonate prior to dyeing?
with tannning, can you dry fully before mordant bath? and, if so/if not, why?

I do eco printing of leaves and have seen many logwood dyed carrier cloths. How does this work
i’m hesitant around using alum and would prefer to use mordants from my garden like walnut. any other mordants i could look into?
how do you do a post bath? post mourdant or post dying
I dye with indigo. I bought some dyed wool to dye with indigo to change the color. I did not mordant it as it had already been dyed, but the indigo is coming off in my hands no matter how often I have rinsed and washed the wool. What can I do to have the indigo adhere to the wood?
How do you work with measurements in percentages (without scale)? Measurements are so difficult for me in dyeing
Hot mordanting or cold mordanting? Does is make a difference?
linda magdalena jonsson
What is your thoughts on almondmilk - Can that be a binder (or a mordant?:) what is a good natural option to alum for cellulose fibers?
I tried to make soda ash from baking bicarb of soda, but not 100% sure it worked, how would I know? How would it affect the colour?
Instructions for dying are always for large vessels, ie., 5 gallon pots… how do you make small batches to use for testing swatches?
Can mordanting in an aluminum pot substitute for mordanting with aluminum sulfate?
i work with wool roving for wetfelting. i have to be careful with pre felting so often do not scour. suggestions for cool water scour?
What is the difference of the 2 different alums?
so what is the best way to scour heavy canvas at home? I just got in some beautiful 11oz 100% hemp canvas in natural.
I made a mistake and scoured silk noise with ivory soap rather than a PH neutral detergent. This fabric had a stiff hand after scouring. Is this because of the soap, or something else?
When you refer to alum, do you mean aluminum acetate or aluminum sulfate?
Amy, as a host there’s usually an option where you can click next to a comment or question and mark it “answered” — to help you see through what are been answered & what hasn’t.
What plant tannins do you like to use with cotton? Like oak gulls? Walnut?
