FEEDBACK FRIDAY: Natural Dye Q&A with Botanical Colors' Founder Kathy Hattori - Shared screen with speaker view
I would like to know how to work with a lump of logwood extract that got damp. maybe in a blog post?
I have mixed old nails with vinegar and the liquid started foaming. What is happening?
longevity of cochineal (shelf life). What about freezing the bug?
Is the fire ash in the air in the PNW affecting your dye process?
How about the shelf life of chemicals? Aluminum acetate?
In one of the feedback Fridays, you mentioned that sometime you put copper pipe into dye baths. Could you explain what dyes baths you are utilizing/how you use copper pipe?
I asked the question about sprinkling the yarn, thanks. What do you do after? you boil it, steam it?
suggestion for dyeing Sally fox cotton knit with marigolds
I’m getting ready to set. Up some big indigo vats and have some 2 yr old indigo extract. Is that still good to use? It’s mostly been in a shaded shelf or still in original shipping envelopes.
To preserve avocado pits and skins, is it critical to freeze them so you can keep them longer?
Have you ever worked with/supplied any costume designers/makers? If so, could you tell me some more about that, and if not do you ever see natural dye used in costume?
can I use acacia powder as a mordant for cellulose fibres Is it similar to Symplocos? Does it also require a pre tannin bath? Do you rise tannin treaded fabrics before mordanting them?
I’d love to hear you recommendation for a fabric source. I see a big price difference from dharma and Maiwa. I’m a newbie hobbiest. not looking to spend $50 on scarves to experiment on!
DIFFERENCES IN PREPARATION, USE, TIME, AND RESULTS FOR 60% REDUCED INDIGO CRYSTALS VS. NON-REDUCED?
how do you dye with lichen?
In Aboubakar’s class we premordanted our cellulose fabric with soda ash; what’s the best to use with protein fibres?
I made a fructose indigo vat, I didn't use it. It does not have the flower anymore, does that matter? Its been 2 months.
I was reading a historical text and it refers to dresses being dyed a ’copperas’ color. Copperas is ferrous sulfate, right ? What color do you think it would be? Not sure what the fiber of the garment would have been.
Do you feel that a copper pot for eco dyeing will produce the most intense colors

Is cold mordanting as good as mordanting with heat.
Water use. In Joy and Catherine Elliis’ book it was the first time I saw the 30:1 ratio for tannin bath iare there any other ratios that you use regularly for dye stuffs or other goods - I’ve always used the ‘does the fabric flow well’ idea - eyeing it rather than measuring it. Thoughts on ratios??
Kathy, LEMON JUICE !!!!!! i dyed both logwood and madder root plus iron afterbath.. squeezed lemon juice and it bleaches out. is it iron? is it both dyes? INDIGO seems to be fine.. please help
Any suggestions on which indigo process works best on silk for a clear blue.
Do you have any experience with Aluminium triformate? Susan Dekel had an interesting post of it this week.
Any experience with mixing an alum solution for "painting" on mordant on handmade abaca or cotton paper? if yes, what is the recipe for making the alum solution. My process is to paint on dye, followed by mordant and then another layer of dye. Drying paper in-between. This is Radha Padma's process.
Hi! What percentage do you recommend for "re-charging" an alum mix that has been used already?
Do you think rust remains on items that are rust dyed using old rusty nails/objects?
KATHY, IF I DYE WITH PURPLE CABBAGE WITH SODIUM BICARBONATE (FOR GET GREEN) AND THEN A SOAK IN INDIGO VAT? DOES THE COLOR MIGHT STAY?
COULD YOU POST ABOUT MAKE PIGMENT (PASTE) FOR BLOCK PRINTING !

Is there a way to keep yarn from “blooming” during scouring. I’m worried what will happen to the quality of the yarn after scouring, mordanting and dyeing with heat.
I am just getting started in natural dying and I’m wondering is it better to mordent over heat or to let the fiber sit in a warm bath for an extended period of time.
airnow.gov to check your air quality😊
I like to work with direct application of natural dyes in a stock solution. I just make a guess for the strength of that stock solution. What’s the some better way to calculate it?
