Hi aj9,

I got a similar call the other day. Did you have 3 powders to mix together? One of the older versions of the kit had only the dye and the reducer+soda ash in only 2 containers. We have learned since then that the kit has a much shorter lifespan if the ash and reducer are in the same package, so we have changed it. 3 separate powders come in the kit now, blue dye powder, reducer, and soda ash.

Also, an older kit can have the dye exposed to moisture. If the blue dye was caked and chunky this could be the problem.

Hi,
Some online articles said vinegar does not help to keep the indigo color from fading.
So I am confused, do you still confirm this matter ? Or do you have the reliable information to explain ?

Many thanks

Yes, the vinegar is not so much to prevent the fading, it is to prevent the high pH from damaging silk of wool which are susceptible to those conditions. The other idea is that the vinegar brings the pH down and that is not good conditions for the reduction, so that may help prevent fading, but that is a very minimal factor.

What we have been finding is that fading is much more likely in high humidity environments and that is why we have trouble reproducing that issue here in CA where it is dry all the time. We get these reports from Houston and Louisiana which have very high humidity. Our working theory is that the water in the air is rewetting some leftover reducer in the fabric and that is causing the color to fade. This was confirmed by an Indigo specialist in the Denim industry. He said a really good washing and maybe multiple rinsings would prevent this. Washing in a detergent such as solar fast wash or synthrapol is highly recommended.

Thank you for the comment so do you also sell the color seal products to maintain an indigo color and is it good to use them ?

Hi, I am not sure what you mean buy color seal? Are you referring to a fixative? Indigo is a different animal and fixatives like the Idye fixative do not work well on it. Unfortunately, Indigo can both wash out and fade in UV. There is not a lot to be done about that other than washing in cold water, and keeping it out of long term UV exposure.

Thank you. My kit was one of the older ones and the powder had become cakey too.

I used an older kit - bought two years ago but never was opened and had all three packages. It never gave me much of a bloom but the fabric turned out fine - or at least it still looks good. Now two days later the vat is blue which is probably due to having the vat open all day when dyeing but closed after that. I added 10 grams of the reducing agent, mixed up, covered and now an hour later no change. Could the reducing agent be too old? Or do I need to add more. The vat is in the dye studio/garage which is warm. Thanks

The bloom or flower is not as important as the color of the dye. If most of the dye is not green, that is an issue.

10 grams of reducer is not that much, I would suggest adding more. A helpful tip if you need more is that the color remover is the same stuff.

Hi, If I want to learn shibori folding in many patterns for indigo dyeing, can you suggest the shibori book for beginner ? Although there are online resources but I assume to get more techniques from the book. Thanks

Shibori: The Inventive Art of Japanese Shaped Resist Dyeing by Yoshiko Wada is really good and has a lot of nice designs in it. Unfortunately, there are tons of Japanese books that haven't been translated to English yet that are also very good, but this is a great place to start.

Shibori for Textile Artists by Janice Gunner is also really good. I like the first one best though. Anyone else have thoughts?
